# eggsampler/acme
[![GoDoc](https://godoc.org/github.com/eggsampler/acme?status.svg)](https://godoc.org/github.com/eggsampler/acme)
[![Build Status](https://travis-ci.com/eggsampler/acme.svg?branch=master)](https://travis-ci.com/eggsampler/acme)
[![Coverage Status](https://coveralls.io/repos/github/eggsampler/acme/badge.svg?branch=master)](https://coveralls.io/github/eggsampler/acme?branch=master)
## About
`eggsampler/acme` is a Go client library implementation for [RFC8555](https://tools.ietf.org/html/rfc8555) (previously ACME v2), specifically for use with the [Let's Encrypt](https://letsencrypt.org/)™ service.
The library is designed to provide a zero external dependency wrapper over exposed directory endpoints and provide objects in easy to use structures.
## Requirements
A Go version of at least 1.11 is required as this repository is designed to be imported as a Go module.
## Usage
Simply import the module into a project,
```go
import "github.com/eggsampler/acme/v3"
```
Note the `/v3` major version at the end. Due to the way modules function, this is the major version as represented in the `go.mod` file and latest git repo [semver](https://semver.org/) tag.
All functions are still exported and called using the `acme` package name.
## Examples
A simple [certbot](https://certbot.eff.org/)-like example is provided in the examples/certbot directory.
This code demonstrates account registration, new order submission, fulfilling challenges, finalising an order and fetching the issued certificate chain.
An example of how to use the autocert package is also provided in examples/autocert.
## Tests
The tests can be run against an instance of [boulder](https://github.com/letsencrypt/boulder) or [pebble](https://github.com/letsencrypt/pebble).
Challenge fulfilment is designed to use the new `challtestsrv` server present inside boulder and pebble which responds to dns queries and challenges as required.
To run tests against an already running instance of boulder or pebble, use the `test` target in the Makefile.
Some convenience targets for launching pebble/boulder using their respective docker compose files have also been included in the Makefile.

[![godoc](https://godoc.org/github.com/letsdebug/letsdebug?status.svg)](https://godoc.org/github.com/letsdebug/letsdebug)
Let's Debug is a diagnostic website, API, CLI and Go package for quickly and accurately finding and reporting issues for any domain that may prevent issuance of a Let's Encrypt SSL certificate for any ACME validation method.
It is motivated by [this community thread](https://community.letsencrypt.org/t/creating-a-webservice-for-analysis-of-common-problems/45836).
## Status
Currently [deployed to letsdebug.net and regularly in use](https://letsdebug.net).
## Problems Detected
| Name | Description | Examples
-------|-------------|--------|
| InvalidMethod, ValidationMethodDisabled, ValidationMethodNotSuitable | Checks the ACME validation method is valid and usable for the provided domain name. | [Example](https://letsdebug.net/*.letsencrypt.org/1) |
| InvalidDomain | Checks the domain is a valid domain name on a public TLD. | [Example](https://letsdebug.net/ooga.booga/2) |
| StatusNotOperational| Checks that the Let's Encrypt service is not experiencing an outage, according to status.io | -
| DNSLookupFailed, TXTRecordError | Checks that the Unbound resolver (via libunbound) is able to resolve a variety records relevant to Let's Encrypt. Discovers problems such as DNSSEC issues, 0x20 mixed case randomization, timeouts etc, in the spirit of jsha's unboundtest.com | [Example](https://letsdebug.net/dnssec-failed.org/3) |
CAAIssuanceNotAllowed | Checks that no CAA records are preventing the issuance of Let's Encrypt certificates. | [Example](https://letsdebug.net/id-rsa.pub/4) |
CAACriticalUnknown | Checks that no CAA critical flags unknown to Let's Encrypt are used | - |
RateLimit | Checks that the domain name is not currently affected by any of the domain-based rate limits imposed by Let's Encrypt, using the public certwatch Postgres interface from Comodo's crt.sh. | [Example](https://letsdebug.net/targettec.ddns.net/13) |
NoRecords, ReservedAddress | Checks that sufficient valid A/AAAA records are present to perform HTTP-01 validation | [Example](https://letsdebug.net/localtest.me/6) |
BadRedirect | Checks that no bad HTTP redirects are present. Discovers redirects that aren't accessible, unacceptable ports, unacceptable schemes, accidental missing trailing slash on redirect. | [Example](https://letsdebug.net/foo.monkas.xyz/7) |
WebserverMisconfiguration | Checks whether the server is serving the wrong protocol on the wrong port as the result of an HTTP-01 validation request. | - |
ANotWorking, AAAANotWorking | Checks whether listed IP addresses are not functioning properly for HTTP-01 validation, including timeouts and other classes of network and HTTP errors. | [Example](https://letsdebug.net/network-fail.foo.monkas.xyz/8) |
MultipleIPAddressDiscrepancy | For domains with multiple A/AAAA records, checks whether there are major discrepancies between the server responses to reveal when the addresses may be pointing to different servers accidentally. | [Example](https://letsdebug.net/v4v6fail.monkas.xyz/51916)
CloudflareCDN | Checks whether the domain is being served via Cloudflare's proxy service (and therefore SSL termination is occurring at Cloudflare) | - |
CloudflareSSLNotProvisioned | Checks whether the domain has its SSL terminated by Cloudflare and Cloudflare has not provisioned a certificate yet (leading to a TLS handshake error). | [Example](https://letsdebug.net/cf-no-ssl.fleetssl.com/10) |
IssueFromLetsEncrypt | Attempts to detect issues with a high degree of accuracy via the Let's Encrypt v2 staging service by attempting to perform an authorization for the domain. Discovers issues such as CA-based domain blacklists & other policies, specific networking issues. | [Example](https://letsdebug.net/bankofamerica.com/12) |
| TXTDoubleLabel | Checks for the presence of records that are doubled up (e.g. `_acme-challenge.example.org.example.org`). Usually indicates that the user has been incorrectly creating records in their DNS user interface. | [Example](https://letsdebug.net/double.monkas.xyz/2477) |
PortForwarding | Checks whether the domain is serving a modem-router administrative interface instead of an intended webserver, which is indicative of a port-forwarding misconfiguration. | [Example](https://letsdebug.net/cdkauffmannnextcloud.duckdns.org/11450) |
| SanctionedDomain | Checks whether the Registered Domain is present on the [USG OFAC SDN List](https://sanctionssearch.ofac.treas.gov/). Updated daily. | [Example](https://letsdebug.net/unomasuno.com.mx/48081) |
| BlockedByNginxTestCookie | Checks whether the HTTP-01 validation requests are being intercepted by [testcookie-nginx-module](https://github.com/kyprizel/testcookie-nginx-module). | [Example](https://letsdebug.net/13513427185.ifastnet.org/51860) |
| HttpOnHttpsPort | Checks whether the server reported receiving an HTTP request on an HTTPS-only port | [Example](https://letsdebug.net/clep-energy.org/107591) |
## Web API Usage
There is a JSON-based API available as part of the web frontend.
### Submitting a test
```bash
$ curl --data '{"method":"http-01","domain":"letsdebug.net"}' -H 'content-type: application/json' https://letsdebug.net
```
```javascript
{"Domain":"letsdebug.net","ID":14}
```
### Submitting a test with custom options
```bash
curl --data '{"method":"http-01","domain":"letsdebug.net","options":{"http_request_path":"custom-path","http_expect_response":"abc123"}}' -H 'content-type: application/json' https://letsdebug.net
```
Available options are as follows:
| Option | Description |
-------|-------------|
`http_request_path` | What path within `/.well-known/acme-challenge/` to use instead of `letsdebug-test` (default) for the HTTP check. Max length 255. |
`http_expect_response` | What exact response to expect from each server during the HTTP check. By default, no particular response is expected. If present and the response does not match, the test will fail with an Error severity. It is highly recommended to always use a completely random value. Max length 255. |
### Viewing tests
```bash
$ curl -H 'accept: application/json' https://letsdebug.net/letsdebug.net/14
```
```javascript
{"id":14,"domain":"letsdebug.net","method":"http-01","status":"Complete","created_at":"2018-04-30T01:58:34.765829Z","started_at":"2018-04-30T01:58:34.769815Z","completed_at":"2018-04-30T01:58:41.39023Z","result":{}}
```
or to view all recent tests
```bash
$ curl -H 'accept: application/json' https://letsdebug.net/letsdebug.net
```
### Performing a query against the Certwatch database
```bash
$ curl "https://letsdebug.net/certwatch-query?q=<urlencoded SQL query>"
```
```javascript
{
"query": "select c.id as crtsh_id, x509_subjectName(c.CERTIFICATE), x509_notAfter(c.CERTIFICATE) from certificate c where x509_notAfter(c.CERTIFICATE) = '2018-06-01 16:25:44' AND x509_issuerName(c.CERTIFICATE) LIKE 'C=US, O=Let''s Encrypt%';",
"results": [
{
"crtsh_id": 346300797,
"x509_notafter": "2018-06-01T16:25:44Z",
"x509_subjectname": "CN=hivdatingzimbabwe.com"
},
/* ... */
]
}
```
## CLI Usage
You can download binaries for tagged releases for Linux for both the CLi and the server [from the releases page](https://github.com/letsdebug/letsdebug/releases).
letsdebug-cli -domain example.org -method http-01 -debug
## Library Usage
```go
import "github.com/letsdebug/letsdebug"
problems, _ := letsdebug.Check("example.org", letsdebug.HTTP01)
```
## Installation
### Dependencies
This package relies on a fairly recent version of libunbound.
* On Debian-based distributions:
`apt install libunbound2 libunbound-dev`
* On EL-based distributions, you may need to build from source because the packages are ancient on e.g. CentOS, but you can try:
`yum install unbound-libs unbound-devel`
* On OSX, [Homebrew](https://brew.sh/) contains the latest version of unbound:
`brew install unbound`
You will also need Go's [dep](https://github.com/golang/dep) dependency manager.
### Releases
You can save time by [downloading tagged releases for 64-bit Linux](https://github.com/letsdebug/letsdebug/releases). Keep in mind you will still need to have libunbound present on your system.
### Building
go get -u github.com/letsdebug/letsdebug/...
cd $GOPATH/src/github.com/letsdebug/letsdebug
make deps
make letsdebug-cli letsdebug-server

# pq - A pure Go postgres driver for Go's database/sql package
[![GoDoc](https://godoc.org/github.com/lib/pq?status.svg)](https://pkg.go.dev/github.com/lib/pq?tab=doc)
## Install
go get github.com/lib/pq
## Features
* SSL
* Handles bad connections for `database/sql`
* Scan `time.Time` correctly (i.e. `timestamp[tz]`, `time[tz]`, `date`)
* Scan binary blobs correctly (i.e. `bytea`)
* Package for `hstore` support
* COPY FROM support
* pq.ParseURL for converting urls to connection strings for sql.Open.
* Many libpq compatible environment variables
* Unix socket support
* Notifications: `LISTEN`/`NOTIFY`
* pgpass support
* GSS (Kerberos) auth
## Tests
`go test` is used for testing. See [TESTS.md](TESTS.md) for more details.
## Status
This package is effectively in maintenance mode and is not actively developed. Small patches and features are only rarely reviewed and merged. We recommend using [pgx](https://github.com/jackc/pgx) which is actively maintained.

# Tests
## Running Tests
`go test` is used for testing. A running PostgreSQL
server is required, with the ability to log in. The
database to connect to test with is "pqgotest," on
"localhost" but these can be overridden using [environment
variables](https://www.postgresql.org/docs/9.3/static/libpq-envars.html).
Example:
PGHOST=/run/postgresql go test
## Benchmarks
A benchmark suite can be run as part of the tests:
go test -bench .
## Example setup (Docker)
Run a postgres container:
```
docker run --expose 5432:5432 postgres
```
Run tests:
```
PGHOST=localhost PGPORT=5432 PGUSER=postgres PGSSLMODE=disable PGDATABASE=postgres go test
```

/*
Package pq is a pure Go Postgres driver for the database/sql package.
In most cases clients will use the database/sql package instead of
using this package directly. For example:
import (
"database/sql"
_ "github.com/lib/pq"
)
func main() {
connStr := "user=pqgotest dbname=pqgotest sslmode=verify-full"
db, err := sql.Open("postgres", connStr)
if err != nil {
log.Fatal(err)
}
age := 21
rows, err := db.Query("SELECT name FROM users WHERE age = $1", age)
…
}
You can also connect to a database using a URL. For example:
connStr := "postgres://pqgotest:password@localhost/pqgotest?sslmode=verify-full"
db, err := sql.Open("postgres", connStr)
Connection String Parameters
Similarly to libpq, when establishing a connection using pq you are expected to
supply a connection string containing zero or more parameters.
A subset of the connection parameters supported by libpq are also supported by pq.
Additionally, pq also lets you specify run-time parameters (such as search_path or work_mem)
directly in the connection string. This is different from libpq, which does not allow
run-time parameters in the connection string, instead requiring you to supply
them in the options parameter.
For compatibility with libpq, the following special connection parameters are
supported:
* dbname - The name of the database to connect to
* user - The user to sign in as
* password - The user's password
* host - The host to connect to. Values that start with / are for unix
domain sockets. (default is localhost)
* port - The port to bind to. (default is 5432)
* sslmode - Whether or not to use SSL (default is require, this is not
the default for libpq)
* fallback_application_name - An application_name to fall back to if one isn't provided.
* connect_timeout - Maximum wait for connection, in seconds. Zero or
not specified means wait indefinitely.
* sslcert - Cert file location. The file must contain PEM encoded data.
* sslkey - Key file location. The file must contain PEM encoded data.
* sslrootcert - The location of the root certificate file. The file
must contain PEM encoded data.
Valid values for sslmode are:
* disable - No SSL
* require - Always SSL (skip verification)
* verify-ca - Always SSL (verify that the certificate presented by the
server was signed by a trusted CA)
* verify-full - Always SSL (verify that the certification presented by
the server was signed by a trusted CA and the server host name
matches the one in the certificate)
See http://www.postgresql.org/docs/current/static/libpq-connect.html#LIBPQ-CONNSTRING
for more information about connection string parameters.
Use single quotes for values that contain whitespace:
"user=pqgotest password='with spaces'"
A backslash will escape the next character in values:
"user=space\ man password='it\'s valid'"
Note that the connection parameter client_encoding (which sets the
text encoding for the connection) may be set but must be "UTF8",
matching with the same rules as Postgres. It is an error to provide
any other value.
In addition to the parameters listed above, any run-time parameter that can be
set at backend start time can be set in the connection string. For more
information, see
http://www.postgresql.org/docs/current/static/runtime-config.html.
Most environment variables as specified at http://www.postgresql.org/docs/current/static/libpq-envars.html
supported by libpq are also supported by pq. If any of the environment
variables not supported by pq are set, pq will panic during connection
establishment. Environment variables have a lower precedence than explicitly
provided connection parameters.
The pgpass mechanism as described in http://www.postgresql.org/docs/current/static/libpq-pgpass.html
is supported, but on Windows PGPASSFILE must be specified explicitly.
Queries
database/sql does not dictate any specific format for parameter
markers in query strings, and pq uses the Postgres-native ordinal markers,
as shown above. The same marker can be reused for the same parameter:
rows, err := db.Query(`SELECT name FROM users WHERE favorite_fruit = $1
OR age BETWEEN $2 AND $2 + 3`, "orange", 64)
pq does not support the LastInsertId() method of the Result type in database/sql.
To return the identifier of an INSERT (or UPDATE or DELETE), use the Postgres
RETURNING clause with a standard Query or QueryRow call:
var userid int
err := db.QueryRow(`INSERT INTO users(name, favorite_fruit, age)
VALUES('beatrice', 'starfruit', 93) RETURNING id`).Scan(&userid)
For more details on RETURNING, see the Postgres documentation:
http://www.postgresql.org/docs/current/static/sql-insert.html
http://www.postgresql.org/docs/current/static/sql-update.html
http://www.postgresql.org/docs/current/static/sql-delete.html
For additional instructions on querying see the documentation for the database/sql package.
Data Types
Parameters pass through driver.DefaultParameterConverter before they are handled
by this package. When the binary_parameters connection option is enabled,
[]byte values are sent directly to the backend as data in binary format.
This package returns the following types for values from the PostgreSQL backend:
- integer types smallint, integer, and bigint are returned as int64
- floating-point types real and double precision are returned as float64
- character types char, varchar, and text are returned as string
- temporal types date, time, timetz, timestamp, and timestamptz are
returned as time.Time
- the boolean type is returned as bool
- the bytea type is returned as []byte
All other types are returned directly from the backend as []byte values in text format.
Errors
pq may return errors of type *pq.Error which can be interrogated for error details:
if err, ok := err.(*pq.Error); ok {
fmt.Println("pq error:", err.Code.Name())
}
See the pq.Error type for details.
Bulk imports
You can perform bulk imports by preparing a statement returned by pq.CopyIn (or
pq.CopyInSchema) in an explicit transaction (sql.Tx). The returned statement
handle can then be repeatedly "executed" to copy data into the target table.
After all data has been processed you should call Exec() once with no arguments
to flush all buffered data. Any call to Exec() might return an error which
should be handled appropriately, but because of the internal buffering an error
returned by Exec() might not be related to the data passed in the call that
failed.
CopyIn uses COPY FROM internally. It is not possible to COPY outside of an
explicit transaction in pq.
Usage example:
txn, err := db.Begin()
if err != nil {
log.Fatal(err)
}
stmt, err := txn.Prepare(pq.CopyIn("users", "name", "age"))
if err != nil {
log.Fatal(err)
}
for _, user := range users {
_, err = stmt.Exec(user.Name, int64(user.Age))
if err != nil {
log.Fatal(err)
}
}
_, err = stmt.Exec()
if err != nil {
log.Fatal(err)
}
err = stmt.Close()
if err != nil {
log.Fatal(err)
}

Notifications
PostgreSQL supports a simple publish/subscribe model over database
connections. See http://www.postgresql.org/docs/current/static/sql-notify.html
for more information about the general mechanism.
To start listening for notifications, you first have to open a new connection
to the database by calling NewListener. This connection can not be used for
anything other than LISTEN / NOTIFY. Calling Listen will open a "notification
channel"; once a notification channel is open, a notification generated on that
channel will effect a send on the Listener.Notify channel. A notification
channel will remain open until Unlisten is called, though connection loss might
result in some notifications being lost. To solve this problem, Listener sends
a nil pointer over the Notify channel any time the connection is re-established
following a connection loss. The application can get information about the
state of the underlying connection by setting an event callback in the call to
NewListener.
A single Listener can safely be used from concurrent goroutines, which means
that there is often no need to create more than one Listener in your
application. However, a Listener is always connected to a single database, so
you will need to create a new Listener instance for every database you want to
receive notifications in.
The channel name in both Listen and Unlisten is case sensitive, and can contain
any characters legal in an identifier (see
http://www.postgresql.org/docs/current/static/sql-syntax-lexical.html#SQL-SYNTAX-IDENTIFIERS
for more information). Note that the channel name will be truncated to 63
bytes by the PostgreSQL server.
You can find a complete, working example of Listener usage at
https://godoc.org/github.com/lib/pq/example/listen.
Kerberos Support
If you need support for Kerberos authentication, add the following to your main
package:
import "github.com/lib/pq/auth/kerberos"
func init() {
pq.RegisterGSSProvider(func() (pq.Gss, error) { return kerberos.NewGSS() })
}
This package is in a separate module so that users who don't need Kerberos
don't have to download unnecessary dependencies.
When imported, additional connection string parameters are supported:
* krbsrvname - GSS (Kerberos) service name when constructing the
SPN (default is `postgres`). This will be combined with the host
to form the full SPN: `krbsrvname/host`.
* krbspn - GSS (Kerberos) SPN. This takes priority over
`krbsrvname` if present.

# Unbound
A wrapper for Unbound in Go.
Unbound's `ub_result` has been extended with an slice of dns.RRs, this alleviates
the need to parse `ub_result.data` yourself.
The website for Unbound is https://unbound.net/, where you can find further documentation.
Tested/compiled to work for versions: 1.4.22 and 1.6.0-3+deb9u1 (Debian Stretch).
Note: using cgo means the executables will use shared libraries (OpenSSL, ldns and libunbound).
The tutorials found here are the originals ones adapted to Go.

// Package unbound implements a wrapper for libunbound(3).
// Unbound is a DNSSEC aware resolver, see https://unbound.net/

// Unbound with trust anchors. With these anchors a DNSSEC
// answer can be validated.
//
// The method's documentation can be found in libunbound(3).
// The names of the methods are in sync with the
// names used in unbound, but the underscores are removed and they
// are in camel-case, e.g. ub_ctx_resolv_conf becomes u.ResolvConf.
// Except for ub_ctx_create() and ub_ctx_delete(),
// which become: New() and Destroy() to be more in line with the standard
// Go practice.
//
// Basic use pattern:
// u := unbound.New()
// defer u.Destroy()
// u.ResolvConf("/etc/resolv.conf")
// u.AddTaFile("trustanchor")
// r, e := u.Resolve("miek.nl.", dns.TypeA, dns.ClassINET)
//
// The asynchronous functions are implemented using goroutines. This
// means the following functions are not useful in Go and therefor
// not implemented: ub_fd, ub_wait, ub_poll, ub_process and ub_cancel.
//
// Unbound's ub_result (named Result in the package) has been modified.
