使用标准库crypto/aes 实现AES加密和解密
代码实现
package main
import (
"crypto/aes"
"encoding/hex"
)
func EncryptAES(key string, plainText string) (string, error) {
cipher, err := aes.NewCipher([]byte(key))
if err != nil {
return "", err
}
out := make([]byte, len(plainText))
cipher.Encrypt(out, []byte(plainText))
return hex.EncodeToString(out), nil
}
func DecryptAES(key string, encryptText string) (string, error) {
decodeText, _ := hex.DecodeString(encryptText)
cipher, err := aes.NewCipher([]byte(key))
if err != nil {
return "", err
}
out := make([]byte, len(decodeText))
cipher.Decrypt(out, decodeText)
return string(out[:]), nil
}
加密
// cipher key
key := "thisisakeymustmorethan16"
// plaintext
text := "This is a secret"
encrypt, err := EncryptAES(key, text)
if err != nil {
log.Fatal(err)
}
fmt.Println(encrypt)
// db647f5df56904ef3463834abc019c1d
解密
// cipher key
key := "thisisakeymustmorethan16"
// decrypt
decrypt := "db647f5df56904ef3463834abc019c1d"
plaintext, err := DecryptAES(key, decrypt)
if err != nil {
log.Fatal(err)
}
fmt.Println(plaintext)
// This is a secret
