## 4.ECC椭圆曲线应用
|
||||
|
||||
**（GO里面只有ECC数字签名的接口，所以我们这里实现了ECC的数字签名功能，ECC椭圆曲线加密使用了区块链以太坊中的相关接口,ECC一般只签名使用加密一般不使用）**
|
||||
|
||||
#### 4.1 ECC使用
|
||||
|
||||
和RSA使用一样，先直接调用GetEccKey()就可以在本地生成一个私钥文件，一个公钥文件
|
||||
|
||||
```
|
||||
func main(){
|
||||
goEncrypt.GetEccKey()
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||

|
||||
rtext, stext, err := goEncrypt.EccSign(msg, privateKey)
|
||||
|
||||
msg := "床前明月光，疑是地上霜，举头望明月，低头思故乡"
|
||||
eccBase64Key, err := ecc.GenerateEccKeyBase64()
|
||||
if err != nil {
|
||||
fmt.Println(err)
|
||||
return
|
||||
}
|
||||
|
||||
fmt.Println("数字签名的消息为：", hex.EncodeToString(rtext)+hex.EncodeToString(stext))
|
||||
|
||||
// 验证数字签名正不正确
|
||||
result := goEncrypt.EccVerifySign(msg, publicKey, rtext, stext)
|
||||
if result { // 如果result返回的是true那么就是本人签名，否则不是，只有私钥加密，相对的公钥验证才可以认为是本人
|
||||
fmt.Println("数字签名正确，是本人")
|
||||
} else {
|
||||
fmt.Println("数字签名错误，不是本人")
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
|
||||
> ECC椭圆曲线技术应用广泛，目前我国居民身份证数字签名技术就是使用的ECC，虚拟货币比特币和以太坊中也使用了ECC技术,ECC加密一般不使用。
|
||||
|
||||
#### 4.3 ECC用作加密使用（非对称加密是用公钥来加密，私钥来解密的，由于GO标准包中没有实现ECC加密的接口，只实现了ECC数字签名的接口，我们找了以太坊源码中的ECC加密的使用方法，稍加改造了一下，拿过来用了，在这里调用了以太坊加密包里面的接口来实现ECC加密的方法，我们把加密的东西二次封装了一下，下载包后就可以直接使用）
|
||||
|
||||
首先还是先得到公钥和私钥
|
||||
|
||||
```
|
||||
func main(){
|
||||
goEncrypt.GetEccKey()
|
||||
} // 这里我们得到的密钥是通过P256曲线得到的，由于之前验证用别的曲线调用以太坊接口会报错
|
||||
```
|
||||
|
||||
然后就可以快速使用了
|
||||
|
||||
