等效于Delphi中的C＃加密/解密代码

Question

我有以下C＃代码来加密/解密字符串：

private static byte[] EncryptString(byte[] clearText, byte[] Key, byte[] IV)
{
    MemoryStream ms = new MemoryStream();
    Rijndael alg = Rijndael.Create();
    alg.Key = Key;
    alg.IV = IV;
    CryptoStream cs = new CryptoStream(ms, alg.CreateEncryptor(), CryptoStreamMode.Write);
    cs.Write(clearText, 0, clearText.Length);
    cs.Close();
    byte[] encryptedData = ms.ToArray();
    return encryptedData;
}

public static string EncryptString(string clearText, string Password)
{
    byte[] clearBytes = System.Text.Encoding.Unicode.GetBytes(clearText);
    PasswordDeriveBytes pdb = new PasswordDeriveBytes(Password, new byte[] { 0x74, 0x68, 0x69, 0x73, 0x69, 0x61, 0x74, 0x65, 0x73, 0x74 });
    byte[] encryptedData = EncryptString(clearBytes, pdb.GetBytes(32), pdb.GetBytes(16));
    return Convert.ToBase64String(encryptedData);
}

private static byte[] DecryptString(byte[] cipherData, byte[] Key, byte[] IV)
{
    MemoryStream ms = new MemoryStream();
    Rijndael alg = Rijndael.Create();
    alg.Key = Key;
    alg.IV = IV;
    CryptoStream cs = new CryptoStream(ms, alg.CreateDecryptor(), CryptoStreamMode.Write);
    cs.Write(cipherData, 0, cipherData.Length);
    cs.Close();
    byte[] decryptedData = ms.ToArray();
    return decryptedData;
}

public static string DecryptString(string cipherText, string Password)
{
    if (!string.IsNullOrEmpty(cipherText))
    {
        byte[] cipherBytes = Convert.FromBase64String(cipherText);
        PasswordDeriveBytes pdb = new PasswordDeriveBytes(Password, new byte[] { 0x74, 0x68, 0x69, 0x73, 0x69, 0x61, 0x74, 0x65, 0x73, 0x74 });
        byte[] decryptedData = DecryptString(cipherBytes, pdb.GetBytes(32), pdb.GetBytes(16));
        return System.Text.Encoding.Unicode.GetString(decryptedData);
    }
    else
    {
        return "";
    }
}

加密的字符串应存储在本地注册表或文件中。 Delphi应用程序也必须访问此字符串。 请注意，由于某种原因，无法将加密/解密代码外包给DLL。

我的问题是我无法在Delphi中生成“ PasswordDerivedBytes”。 有人可以给我一个提示如何工作吗？

我建议您使用Delphi Encryption Compedium 。 它几乎具有您需要加密的所有内容，并且拥有一些大多数可以完成您想做的事的示例。
