我正在尝试使用golang生成dkim密钥,我当前的代码是:
import (
"crypto/rand"
"crypto/rsa"
"crypto/x509"
"encoding/asn1"
"encoding/gob"
"encoding/pem"
"fmt"
"os"
)
func Keymaker(path string) {
reader := rand.Reader
bitSize := 2048
key, err := rsa.GenerateKey(reader, bitSize)
checkError(err)
publicKey := key.PublicKey
//saveGobKey("private.key", key)
savePEMKey(path+".priv", key)
//saveGobKey("public.key", publicKey)
savePublicPEMKey(path+".pub", publicKey)
}
func savePEMKey(fileName string, key *rsa.PrivateKey) {
outFile, err := os.Create(fileName)
checkError(err)
defer outFile.Close()
var privateKey = &pem.Block{
Type: "PRIVATE KEY",
Bytes: x509.MarshalPKCS1PrivateKey(key),
}
err = pem.Encode(outFile, privateKey)
checkError(err)
}
func savePublicPEMKey(fileName string, pubkey rsa.PublicKey) {
asn1Bytes, err := asn1.Marshal(pubkey)
checkError(err)
var pemkey = &pem.Block{
Type: "PUBLIC KEY",
Bytes: asn1Bytes,
}
pemfile, err := os.Create(fileName)
checkError(err)
defer pemfile.Close()
err = pem.Encode(pemfile, pemkey)
checkError(err)
}
func checkError(err error) {
if err != nil {
fmt.Println("Fatal error ", err.Error())
os.Exit(1)
}
}
代码正在运行,生成dkim私钥/公钥,问题是如果我使用此站点生成密钥,则此密钥会由发件人返回不良密钥:https://easydmarc.com/tools/dkim-record-generator/密钥结果有效。
这是我在dns中的dkim设置:
v=DKIM1;t=s;p=MIGJAoGBD1DSPRFFTujiCAiadP9ZeA6eAyf0GktfCQO2WKbrAx2Cu15y2A+agQMWNTmZbbhcznGZiz3kA9y7c0wOqN2iaJchBAxt4qdg1vUhy+6CkSZcY5bdm8uOxsXW3gjOTyZrOur/c118wMTOmSJKHOjn9xLG3ta8tXJtqab8idtx4TlBAgMBAAE=
我尝试低估easydmarc.com生成的密钥正常工作的方式,而golang密钥无效。有什么想法吗?
