Golang生成公钥私钥

//RSA公钥私钥产生
func GenRsaKey(bits int) (publicKeyStr, privateKeyStr string, err error) {
   // 生成私钥文件
   privateKey, err := rsa.GenerateKey(rand.Reader, bits)
   if err != nil {
      return
   }
   derStream := x509.MarshalPKCS1PrivateKey(privateKey)
   block := &pem.Block{
      Type:  "RSA PRIVATE KEY",
      Bytes: derStream,
   }
   bufferPrivate := new(bytes.Buffer)
   err = pem.Encode(bufferPrivate, block)
   if err != nil {
      return
   }
   privateKeyStr = bufferPrivate.String()
   // 生成公钥文件
   publicKey := &privateKey.PublicKey
   derPkix, err := x509.MarshalPKIXPublicKey(publicKey)
   if err != nil {
      return
   }
   block = &pem.Block{
      Type:  "PUBLIC KEY",
      Bytes: derPkix,
   }
   bufferPublic := new(bytes.Buffer)
   err = pem.Encode(bufferPublic, block)
   if err != nil {
      return

   publicKeyStr = bufferPublic.String()
   log.Debug("-------------公钥----------------")
   log.Debug("\r", publicKeyStr)
   log.Debug("--------------私钥---------------")
   log.Debug("\r", privateKeyStr)
   return
