How to implement the encryption, decryption and interconnection of the national secret SM4 and SM2 algorithms in Go?
How to implement the encryption, decryption and interconnection of the national secret SM4 and SM2 algorithms in Go?
Detailed explanation of the encryption, decryption and interconnection of Go language SM4 and SM2
This article explains in detail how to use Go language to implement the encryption and decryption of the SM4 and SM2 algorithms, and ensure interoperability with Java applications (such as those using the hutool toolkit). This requires the combination of asymmetric encryption algorithm SM2 and symmetric encryption algorithm SM4 to take into account data security and efficiency.
Encryption process:
- SM4 symmetric encryption: The sender first randomly generates a session key
secretidcontent. Use this key to SM4 encryption of the message body. The encrypted result is used as the body content of the final message. Go language can use thegithub.com/emmansun/gmsmlibrary to implement SM4 encryption. The code example is as follows:
package main
import (
"fmt"
"github.com/emmansun/gmsm/sm4"
)
func main() {
// ... (Get the message body, generate secretidcontent) ...
cipher, _ := sm4.NewCipher([]byte(secretidcontent))
// ... (SM4 encryption body) ...
}- SM2 asymmetric encryption: Then, using the receiving party's public key, SM2 encryption is performed on
secretidcontentgenerated in step 1. The encryption result is stored in thesecretidfield of the message header. Thegithub.com/emmansun/gmsmlibrary also provides SM2 encryption function. Code example:
package main
import (
"fmt"
"github.com/emmansun/gmsm/sm2"
)
func main() {
// ... (Get the receiver's public key, secretidcontent) ...
publicKey, _ := sm2.ParsePublicKey(publicKeyBytes)
encryptedSecretid, _ := sm2.Encrypt(publicKey, []byte(secretidcontent))
// ... (Put encryptedsecretid into header's secretid) ...
}Decryption process:
- SM2 asymmetric decryption: After receiving the message, the receiver extracts
secretidcontent from the header. Use your own private key to perform SM2 decryption to obtain thesecretidcontentkey generated in step 1.
package main
import (
"fmt"
"github.com/emmansun/gmsm/sm2"
)
func main() {
// ... (get private key, secretid in header) ...
privateKey, _ := sm2.ParsePrivateKey(privateKeyBytes)
secretidcontent, _ := sm2.Decrypt(privateKey, encryptedSecretid)
// ...
}- SM4 symmetric decryption: Finally, use the
secretidcontentkey obtained by decryption to SM4 decrypt the message body to obtain the original message content.
package main
import (
"fmt"
"github.com/emmansun/gmsm/sm4"
)
func main() {
// ... (get body, secretIdContent) ...
cipher, _ := sm4.NewCipher([]byte(secretIdContent))
// ... (SM4 decrypted body) ...
} Important tips: The above code is for reference only. In actual applications, error handling, parameter verification, and security issues such as key management are required. Please read the documentation of github.com/emmansun/gmsm library carefully and learn in-depth its functions and usage methods.
