public static byte[] Encrypt(byte[] plainData,string salt)
    {
        DESCryptoServiceProvider DES = new DESCryptoServiceProvider();
        DES.Key = ASCIIEncoding.ASCII.GetBytes(salt);
        DES.IV = ASCIIEncoding.ASCII.GetBytes(salt);
        ICryptoTransform desencrypt = DES.CreateEncryptor();
        byte[] encryptedData = desencrypt.TransformFinalBlock(plainData,plainData.Length);
        return encryptedData;
    }

    private string GetEncryptedKey(string key)
    {
        return BitConverter.ToString(KeyGeneratorForm.Encrypt(ASCIIEncoding.ASCII.GetBytes(key),"abcdefgh")).Replace("-","");
    }

我试图在PHP中执行相同的操作：@H_301_4@

function get_encrypted_key($key){
    $salt = "abcdefgh";
    return bin2hex(mcrypt_encrypt(MCRYPT_DES,$salt,$key,MCRYPT_MODE_CBC,$salt));
}

但是,结果中存在小的差异,因为最后16个字符总是不同的：@H_301_4@

With key "Benjamin Franklin":
C# : 0B3C6E5DF5D747FB3C50DE952FECE3999768F35B890BC391
PHP: 0B3C6E5DF5D747FB3C50DE952FECE3993A881F9AF348C64D

With key "President Franklin D Roosevelt":
C# : C119B50A5A7F8C905A86A43F5694B4D7DD1E8D0577F1CEB32A86FABCEA5711E1
PHP: C119B50A5A7F8C905A86A43F5694B4D7DD1E8D0577F1CEB37ACBE60BB1D21F3F

我还尝试使用以下代码对我的密钥执行填充转换：@H_301_4@

function get_encrypted_key($key){
    $salt = "abcdefgh";

    $extra = 8 - (strlen($key) % 8);
    if($extra > 0) {
        for($i = 0; $i < $extra; $i++) {
            $key.= "\0";
        }
    }

    return bin2hex(mcrypt_encrypt(MCRYPT_DES,$salt));
}

但我最终得到的结果与没有填充相同.@H_301_4@
