GO语言实现RSA 加密和解密的实现
小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.
RSA 加密和解密的實現(xiàn)
openssl生成私鑰
openssl genrsa -out rsa_private_key.pem 1024openssl生成公鑰
openssl rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem實現(xiàn) RSA 加密解密
package main import ( "crypto/rand" "crypto/rsa" "crypto/x509" "encoding/base64" "encoding/pem" "errors" "fmt" ) // 可通過openssl產(chǎn)生 //openssl genrsa -out rsa_private_key.pem 1024 var privateKey = []byte(` -----BEGIN RSA PRIVATE KEY----- MIICXQIBAAKBgQDfw1/P15GQzGGYvNwVmXIGGxea8Pb2wJcF7ZW7tmFdLSjOItn9 kvUsbQgS5yxx+f2sAv1ocxbPTsFdRc6yUTJdeQolDOkEzNP0B8XKm+Lxy4giwwR5 LJQTANkqe4w/d9u129bRhTu/SUzSUIr65zZ/s6TUGQD6QzKY1Y8xS+FoQQIDAQAB AoGAbSNg7wHomORm0dWDzvEpwTqjl8nh2tZyksyf1I+PC6BEH8613k04UfPYFUg1 0F2rUaOfr7s6q+BwxaqPtz+NPUotMjeVrEmmYM4rrYkrnd0lRiAxmkQUBlLrCBiF u+bluDkHXF7+TUfJm4AZAvbtR2wO5DUAOZ244FfJueYyZHECQQD+V5/WrgKkBlYy XhioQBXff7TLCrmMlUziJcQ295kIn8n1GaKzunJkhreoMbiRe0hpIIgPYb9E57tT /mP/MoYtAkEA4Ti6XiOXgxzV5gcB+fhJyb8PJCVkgP2wg0OQp2DKPp+5xsmRuUXv 720oExv92jv6X65x631VGjDmfJNb99wq5QJBAMSHUKrBqqizfMdOjh7z5fLc6wY5 M0a91rqoFAWlLErNrXAGbwIRf3LN5fvA76z6ZelViczY6sKDjOxKFVqL38ECQG0S pxdOT2M9BM45GJjxyPJ+qBuOTGU391Mq1pRpCKlZe4QtPHioyTGAAMd4Z/FX2MKb 3in48c0UX5t3VjPsmY0CQQCc1jmEoB83JmTHYByvDpc8kzsD8+GmiPVrausrjj4p y2DQpGmUic2zqCxl6qXMpBGtFEhrUbKhOiVOJbRNGvWW -----END RSA PRIVATE KEY----- `) //openssl //openssl rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem var publicKey = []byte(` -----BEGIN PUBLIC KEY----- MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDfw1/P15GQzGGYvNwVmXIGGxea 8Pb2wJcF7ZW7tmFdLSjOItn9kvUsbQgS5yxx+f2sAv1ocxbPTsFdRc6yUTJdeQol DOkEzNP0B8XKm+Lxy4giwwR5LJQTANkqe4w/d9u129bRhTu/SUzSUIr65zZ/s6TU GQD6QzKY1Y8xS+FoQQIDAQAB -----END PUBLIC KEY----- `) // 加密 func RsaEncrypt(origData []byte) ([]byte, error) { //解密pem格式的公鑰 block, _ := pem.Decode(publicKey) if block == nil { return nil, errors.New("public key error") } // 解析公鑰 pubInterface, err := x509.ParsePKIXPublicKey(block.Bytes) if err != nil { return nil, err } // 類型斷言 pub := pubInterface.(*rsa.PublicKey) //加密 return rsa.EncryptPKCS1v15(rand.Reader, pub, origData) } // 解密 func RsaDecrypt(ciphertext []byte) ([]byte, error) { //解密 block, _ := pem.Decode(privateKey) if block == nil { return nil, errors.New("private key error!") } //解析PKCS1格式的私鑰 priv, err := x509.ParsePKCS1PrivateKey(block.Bytes) if err != nil { return nil, err } // 解密 return rsa.DecryptPKCS1v15(rand.Reader, priv, ciphertext) } func main() { data, _ := RsaEncrypt([]byte("hello world")) fmt.Println(base64.StdEncoding.EncodeToString(data)) origData, _ := RsaDecrypt(data) fmt.Println(string(origData)) }總結
