不再支持mcrypt
。我必须创建一个具有完全相同输出的OpenSSL替代方案,因为我只能访问一半代码库。我的尝试都失败了。如您所见,OS与MC不匹配。我尝试了不同的 $methods
以及OPENSSL_RAW_DATA | OPENSSL_ZERO_PADDING
的组合。
我哪里错了?
const n = "\n";
$text= 'hello my friends';
$method = 'AES-128-CBC';
$key = base64_decode('AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA');
$text = base64_decode('MDEyMzQ1Njc4OUFCQ0RFRgAAAAYxMjM0NTYxMjMDAwM=');
$size = openssl_cipher_iv_length($method);
$iv = substr($key, 0, $size);
// MCRYPT METHOD
$module = mcrypt_module_open(MCRYPT_RIJNDAEL_128, '', MCRYPT_MODE_CBC, '');
mcrypt_generic_init($module, $key, $iv);
$mcrypt = mcrypt_generic($module, $text);
// OPENSSL METHOD
$method = 'AES-128-CBC';
$openssl = openssl_encrypt($text, $method, $key, OPENSSL_RAW_DATA | OPENSSL_ZERO_PADDING, $iv);
echo "MC: " . base64_encode($mcrypt) . n;
echo "OS: " . base64_encode($openssl) . n;

答案 0 :(得分:3)
Mcrypts: MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC
相当于:
OPENSSL: AES-256-CBC
我不知道为什么会有区别,但改变128 to 256
为我解决了这个问题。
