谢谢大家.
如下,有c#的加解密方法,我自己写了个php7的实现.但是加解密的结果和c#的完全不一样,请问哪里错了?本人菜鸟,多谢各位.
c
public static string Decrypt(string Text, string sKey)
{
DESCryptoServiceProvider provider = new DESCryptoServiceProvider();
int num = Text.Length / 2;
byte[] buffer = new byte[num];
for (int i = 0; i
php7
public function encrypt($input, $key)
{
$size = mcrypt_get_block_size(MCRYPT_DES, MCRYPT_MODE_CBC);
$input = $this->pkcs5_pad($input, $size);
$td = mcrypt_module_open(MCRYPT_DES, '', MCRYPT_MODE_CBC, '');
$iv = mcrypt_create_iv(mcrypt_enc_get_iv_size($td), MCRYPT_RAND);
mcrypt_generic_init($td, $key, $iv);
$data = mcrypt_generic($td, $input);
mcrypt_generic_deinit($td);
mcrypt_module_close($td);
$data = base64_encode($data);
return $data;
}
private function pkcs5_pad($text, $blocksize)
{
$pad = $blocksize - (strlen($text) % $blocksize);
return $text . str_repeat(chr($pad), $pad);
}
public function decrypt($sStr, $sKey)
{
$decrypted = mcrypt_decrypt(
MCRYPT_DES,
$sKey,
base64_decode($sStr),
MCRYPT_MODE_CBC
);
$dec_s = strlen($decrypted);
$padding = ord($decrypted[$dec_s - 1]);
$decrypted = substr($decrypted, 0, -$padding);
return $decrypted;
}

使用PHP自带的OpenSSL不好了?
