以下是我在Node.js中的代码:
var crypto = require('crypto')
function encryptstring(str) {
var cipher = crypto.createCipheriv('aes-256-cbc', 'NFd6N3v1nbL47FK0xpZjxZ7NY4fYpNYd', 'TestingIV1234567'),
encrypted = cipher.update(str, 'utf-8', 'base64');
encrypted += cipher.final('base64');
return encrypted;
}
console.log(encryptstring("Testing 111111111111111111111111111111111111111111"))
这段代码返回的是:w2f0vBP2hRfgVqssqOluk68Qxkc9LXFESc0ZGzPBq3p6f/x/LbwBbg1XOoRr7I/DAtESJGdweKG6nL9m8RfewA==
下面是Go代码:
package main
import (
"crypto/aes"
"crypto/cipher"
"encoding/base64"
"fmt"
)
// decrypt from base64 to decrypted string
func decrypt(key []byte, iv []byte, cryptoText string) string {
ciphertext, _ := base64.URLEncoding.DecodeString(cryptoText)
block, err := aes.NewCipher(key)
if err != nil {
panic(err)
}
if len(ciphertext) < aes.BlockSize {
panic("ciphertext too short")
}
ciphertext = ciphertext[aes.BlockSize:]
stream := cipher.NewCFBDecrypter(block, iv)
stream.XORKeyStream(ciphertext, ciphertext)
return fmt.Sprintf("%s", ciphertext)
}
func main() {
encKey := "NFd6N3v1nbL47FK0xpZjxZ7NY4fYpNYd"
iv := "TestingIV1234567"
stringtodecrypt := "w2f0vBP2hRfgVqssqOluk68Qxkc9LXFESc0ZGzPBq3p6f/x/LbwBbg1XOoRr7I/DAtESJGdweKG6nL9m8RfewA=="
stringtodecrypt = decrypt([]byte(encKey), []byte(iv), stringtodecrypt)
fmt.Println(string(stringtodecrypt))
}
这会返回_▒▒▒6▒▒d,O▒ob"▒
很多Go代码是从https://gist.github.com/manishtpatel/8222606中获取的。
我也尝试了这个问题: How do I decrypt an AES256 bit cipher in golang that was encrypted in nodejs?(由于在此情况下不需要hex.DecodeString
),但它会抛出一个错误,说:panic: crypto/cipher:input not full blocks
当时我使用的代码如下:
func main() {
encKey := "NFd6N3v1nbL47FK0xpZjxZ7NY4fYpNYd"
iv := "TestingIV1234567"
stringtodecrypt := "w2f0vBP2hRfgVqssqOluk68Qxkc9LXFESc0ZGzPBq3p6f/x/LbwBbg1XOoRr7I/DAtESJGdweKG6nL9m8RfewA=="
block, err := aes.NewCipher([]byte(encKey))
if err != nil {
panic(err)
}
mode := cipher.NewCBCDecrypter(block, []byte(iv))
mode.CryptBlocks([]byte(stringtodecrypt), []byte(stringtodecrypt))
fmt.Println(string(stringtodecrypt))
}
我已经搜索了很多,但似乎无法弄清楚这个问题。
我做错了什么?
