我知道关于PHP Java AES CBC加密的stackoverflow有很多讨论,但没有一个能解决我的问题
这是java函数:
public static String encrypt(String input, String key){
byte[] crypted = null;
SecretKeySpec skey = new SecretKeySpec(getHash("MD5", key), "AES");
IvParameterSpec iv = new IvParameterSpec(new byte[] { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 });
Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
cipher.init(Cipher.ENCRYPT_MODE, skey, iv);
crypted = cipher.doFinal(input.getBytes());
return new String(Base64.encodeBase64(crypted));
}
private static byte[] getHash(String algorithm, String text) {
try {
byte[] bytes = text.getBytes("UTF-8");
final MessageDigest digest = MessageDigest.getInstance(algorithm);
digest.update(bytes);
return digest.digest();
} catch (final Exception ex) {
throw new RuntimeException(ex.getMessage());
}
}
以下是我在PHP中所做的事情
public static function encrypt($input, $key) {
$key = hash('md5', $key, true);
$iv = '0000000000000000';
return openssl_encrypt($input, 'aes-128-cbc', $key, 0, $iv);
}
让我们看看结果
key:"790757e76c8942f995675b247aa57c2a"
input:"1234"
result in java:UfczMtIAm8ewSuIGRdPTDQ==
result in PHP:wd/OTHoIXwgHGDHcj8OTgg==
在php中,我也使用其他方法,例如mcrypt_encrypt
,mcrypt_generic
和pkcs5填充(请参阅代码打击),所有这些方法都可以获得与openssl_encrypt
相同的加密,但仍与Java函数结果
public static function encrypt($input, $key) {
$key = hash('md5', $key, true);
$iv = '0000000000000000';
$size = mcrypt_get_block_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC);
$input = Security::pkcs5_pad($input, $size);
$encrypted = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $key, $input, MCRYPT_MODE_CBC, $iv);
// output wd/OTHoIXwgHGDHcj8OTgg==
echo base64_encode($encrypted);
$td = mcrypt_module_open(MCRYPT_RIJNDAEL_128, '', MCRYPT_MODE_CBC, '');
mcrypt_generic_init($td, $key, $iv);
$data = mcrypt_generic($td, $input);
mcrypt_generic_deinit($td);
mcrypt_module_close($td);
$data = base64_encode($data);
// output wd/OTHoIXwgHGDHcj8OTgg==
echo $data;
}
private static function pkcs5_pad ($text, $blocksize) {
$pad = $blocksize - (strlen($text) % $blocksize);
return $text . str_repeat(chr($pad), $pad);
}
我注意到另一个奇怪的事情,如果我将密码方法从CBC更改为ECB,java和php加密都会相同,但遗憾的是,对于访问第三方API,我必须使用CBC
答案 0 :(得分:2)
终于明白了
"/myAssembley;component/Resources/image1.png"
应该用
替换它$iv = '0000000000000000';
我从其他地方复制它,并认为$iv = str_repeat(chr(0), 16);
等于'0000000000000000'
,这完全错了..
