我正在尝试将我的Java代码转换为Node.js代码。
在加密方面遇到了一些问题。
这是我的Java代码:编译后的代码
import javax.crypto.Cipher;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;
import java.io.UnsupportedEncodingException;
import java.security.GeneralSecurityException;
import java.util.Base64;
public class AESCBCPKCS5Encryption {
private static final String ALGORITHM = "AES/CBC/PKCS5Padding";
public static String encrypt(String message, String key) throws GeneralSecurityException, UnsupportedEncodingException {
if (message == null || key == null) {
throw new IllegalArgumentException("text to be encrypted and key should not be null");
}
Cipher cipher = Cipher.getInstance(ALGORITHM);
byte[] messageArr = message.getBytes();
SecretKeySpec keySpec = new SecretKeySpec(Base64.getDecoder().decode(key), "AES");
byte[] ivParams = new byte[16];
byte[] encoded = new byte[messageArr.length + 16];
System.arraycopy(ivParams, 0, encoded, 0, 16);
System.arraycopy(messageArr, 0, encoded, 16, messageArr.length);
cipher.init(Cipher.ENCRYPT_MODE, keySpec, new IvParameterSpec(ivParams));
byte[] encryptedBytes = cipher.doFinal(encoded);
encryptedBytes = Base64.getEncoder().encode(encryptedBytes);
return new String(encryptedBytes);
}
public static String decrypt(String encryptedStr, String key) throws GeneralSecurityException, UnsupportedEncodingException {
if (encryptedStr == null || key == null) {
throw new IllegalArgumentException("text to be decrypted and key should not be null");
}
Cipher cipher = Cipher.getInstance(ALGORITHM);
SecretKeySpec keySpec = new
SecretKeySpec(Base64.getDecoder().decode(key), "AES");
byte[] encoded = encryptedStr.getBytes();
encoded = Base64.getDecoder().decode(encoded);
byte[] decodedEncrypted = new byte[encoded.length - 16];
System.arraycopy(encoded, 16, decodedEncrypted, 0, encoded.length - 16);
byte[] ivParams = new byte[16];
System.arraycopy(encoded, 0, ivParams, 0, ivParams.length);
cipher.init(Cipher.DECRYPT_MODE, keySpec, new IvParameterSpec(ivParams));
byte[] decryptedBytes = cipher.doFinal(decodedEncrypted);
return new String(decryptedBytes);
}
public static void main(String[] args) throws GeneralSecurityException, UnsupportedEncodingException {
String str = "<Request xmlns=\"http://www.kotak.com/schemas/CorpCCPaymentsOTP/CorpCCPaymentsOTP.xsd\" ><username>ENKASH</username><password>Corp@123</password><SrcAppCd>ENKA SH</SrcAppCd><RefNo>Ref1111111111</RefNo><CardNo>4280933990002698</CardNo ><OTP>12345</OTP></Request>";
String key = "e3a74e3c7599f3ab4601d587bd2cc768";
String enc = encrypt(str, key);
System.out.println(enc);
String dec = decrypt(enc, key);
System.out.println(dec);
}
}
这是我的JavaScript代码:
var crypto = require('crypto');
function getAlgorithm(keyBase64) {
var key = Buffer.from(keyBase64, 'base64');
switch (key.length) {
case 16:
return 'aes-128-cbc';
case 32:
return 'aes-256-cbc';
}
throw new Error('Invalid key length: ' + key.length);
}
function encrypt(plainText, keyBase64, ivBase64) {
const key = Buffer.from(keyBase64, 'base64');
const iv = Buffer.from(ivBase64, 'base64');
const cipher = crypto.createCipheriv(getAlgorithm(keyBase64), key, iv);
let encrypted = cipher.update(plainText, 'utf8', 'base64');
encrypted += cipher.final('base64');
return encrypted;
}
function decrypt(messagebase64, keyBase64, ivBase64) {
const key = Buffer.from(keyBase64, 'base64');
const iv = Buffer.from(ivBase64, 'base64');
const decipher = crypto.createDecipheriv(getAlgorithm(keyBase64), key, iv);
let decrypted = decipher.update(messagebase64, 'base64');
decrypted += decipher.final();
return decrypted;
}
var keyBase64 = "DWIzFkO22qfVMgx2fIsxOXnwz10pRuZfFJBvf4RS3eY=";
var ivBase64 = 'e3a74e3c7599f3ab4601d587bd2cc768';
var plainText = '<Request xmlns="http://www.kotak.com/schemas/CorpCCPaymentsOTP/CorpCCPaymentsOTP.xsd"><username>ENKASH</username><password>Corp@123</password><SrcAppCd>ENKA SH</SrcAppCd><RefNo>Ref1111111111</RefNo><CardNo>4280933990002698</CardNo ><OTP>12345</OTP></Request>';
var cipherText = encrypt(plainText, keyBase64, ivBase64);
var decryptedCipherText = decrypt(cipherText, keyBase64, ivBase64);
console.log('Algorithm: ' + getAlgorithm(keyBase64));
console.log('Plaintext: ' + plainText);
console.log('Ciphertext: ' + cipherText);
console.log('Decoded Ciphertext: ' + decryptedCipherText);
加密出现错误,
我在这里做错了什么?
