Question

我正在尝试解密我加密的一些文本，但是，我得到了奇怪的字符：

لمح쒏栎ル찢샋㨺⸸⓬왛㓘瞅苽景崲胏퐛㽵㈊褗邌≟䒙쉪ਊᮻ

以下是加密文字：

1CU + 45SHXGsSHmJiYuZx3uQYPr6N4vXUwIvzYtDcUs05l4tZZT4jJBjlG6uJbzZgjQOwjRwwTvmowC3FGlbU / IsvM6U3il3i

如何获得常规文字？

       public static string DecryptData(string encryptedtext, string key)
    {
        key = m_Key;
        try
        {
            TripleDESCryptoServiceProvider TripleDes = new TripleDESCryptoServiceProvider();
            TripleDes.Key = TruncateHash(key, TripleDes.KeySize / 8);
            TripleDes.IV = TruncateHash("", TripleDes.BlockSize / 8);

            // Convert the encrypted text string to a byte array.
            byte[] encryptedBytes = Convert.FromBase64String(encryptedtext);

            // Create the stream.
            System.IO.MemoryStream ms = new System.IO.MemoryStream();
            // Create the decoder to write to the stream.
            CryptoStream decStream = new CryptoStream(ms, TripleDes.CreateDecryptor(), System.Security.Cryptography.CryptoStreamMode.Write);

            // Use the crypto stream to write the byte array to the stream.
            decStream.Write(encryptedBytes, 0, encryptedBytes.Length);
            decStream.FlushFinalBlock();

            // Convert the plaintext stream to a string.
            return System.Text.Encoding.Unicode.GetString(ms.ToArray());
        }
        catch (Exception)
        {
            return DecryptDataOldKey(encryptedtext, string.Empty);
        }
    }

这是我的加密代码：

        public static string EncryptData(string plaintext, string key = "")
    {
        TripleDESCryptoServiceProvider TripleDes = new TripleDESCryptoServiceProvider();
        TripleDes.Key = TruncateHash(key, TripleDes.KeySize / 8);
        TripleDes.IV = TruncateHash("", TripleDes.BlockSize / 8);

        // Convert the plaintext string to a byte array.
        byte[] plaintextBytes = System.Text.Encoding.Unicode.GetBytes(plaintext);

        // Create the stream.
        System.IO.MemoryStream ms = new System.IO.MemoryStream();
        // Create the encoder to write to the stream.
        CryptoStream encStream = new CryptoStream(ms, TripleDes.CreateEncryptor(), System.Security.Cryptography.CryptoStreamMode.Write);

        // Use the crypto stream to write the byte array to the stream.
        encStream.Write(plaintextBytes, 0, plaintextBytes.Length);
        encStream.FlushFinalBlock();

        // Convert the encrypted stream to a printable string.
        return Convert.ToBase64String(ms.ToArray());
    }

加密和解密数据时应使用相同的编码，例如 UTF8 。将 System.Text.Encoding.Unicode 更改为 System.Text.Encoding.UTF8 。
