我正在尝试将JAVA加密更改为PHP,并产生完全相同的结果。 我有以下准则。 带有PKCS5填充对称加密方案的AES ‐ CBC:
加密密钥的大小为128位。
初始化向量(IV):
-在每个请求中将使用新的随机IV。 -在单个Web服务请求中,对所有加密字段进行加密时将使用相同的IV。 -此IV将在SOAP Header中传递,名称为“ IV”。 IV值将采用Base64编码。
我已经尝试过https://gist.github.com/thomasdarimont/fae409eaae2abcf83bd6633b961e7f00
public class AESEncryptionUtil {
public static final String CLASS_NAME = AESEncryptionUtil.class.getName(); private static final int KEY_SIZE = 16;
private static final String ALGORITHM_AES = "AES";
public final static String ALGORITHM_AES_CBC = "AES/CBC/PKCS5Padding";
private static Key generateKey(String keyValue) throws Exception { Key key = null ;
if (keyValue!=null && keyValue.length()==KEY_SIZE){
byte[] byteKey = keyValue.substring(0, KEY_SIZE).getBytes("UTF-8");
key = new SecretKeySpec(byteKey, ALGORITHM_AES);
}else{
System.out.println("Not generating the Key!! "+keyValue); }
return key;
}
/**
* Return Base64 Encoded value of IV *
* @param keyValue * @return
* @throws Exception */
public static String generateIV(String keyValue) throws Exception { String iv = null ;
Key key = generateKey(keyValue); if (key!=null){
Cipher cipher = Cipher.getInstance(ALGORITHM_AES_CBC); cipher.init(Cipher.ENCRYPT_MODE, key); AlgorithmParameters params = cipher.getParameters();
iv = new BASE64Encoder().encode(params.getParameterSpec(IvParameterSpec.class).getIV());
}else{
System.out.println("No IV generated ...");
}
return iv; }
/**

*Encryption Key value * @param plainVal -
*Value to be encrypted * @return - encrypted String Value * @throws Exception
*/
public static String encrypt(String encKey, String plainVal, String currentIV) throws Exception {
String encryptedText = null ; Key key = generateKey(encKey);
if (key!=null && currentIV!=null && plainVal!=null){
Cipher c = Cipher.getInstance(ALGORITHM_AES_CBC);
c.init(Cipher.ENCRYPT_MODE, key, new IvParameterSpec(new BASE64Decoder().decodeBuffer(currentIV)));
byte[] encValue = c.doFinal(plainVal.getBytes()); encryptedText= new BASE64Encoder().encode(encValue);
}else{
System.out.println("Invalid input passed to encrypt !! keyValue="+encKey+", IV="+currentIV+", valueToEnc="+plainVal);
}
return encryptedText; }
}
答案 0 :(得分:0)
我设法找到了工作
<?php
$string = "online1234";
$key = "haskingvista127$";
$iv = base64_encode(openssl_random_pseudo_bytes(openssl_cipher_iv_length('aes-128-cbc')));
$encodedEncryptedData = base64_encode(openssl_encrypt($string, "AES-128-CBC", $key, OPENSSL_RAW_DATA, base64_decode($iv)));
$decryptedData = openssl_decrypt(base64_decode($encodedEncryptedData), "AES-128-CBC", $key, OPENSSL_RAW_DATA, base64_decode($iv));
?>
希望这可能对其他人有帮助
