我在web.config中使用此机器密钥

I use Machine Key for Encrypt my Password in membership. How can I decrypt it?

I user this Machine key in web.config

<machinekey>
validationKey="56AB7132992003EE87F74AE4D9675D65EED8018D3528C0B8874905B51940DEAF6B85F1D922D19AB8F69781B2326A2F978A064708822FD8C54ED74CADF8592E17"
decryptionKey="A69D80B92A16DFE1698DFE86D4CED630FA56D7C1661C8D05744449889B88E8DC"
validation="SHA1" decryption="AES"/></machinekey>

推荐答案

你永远不应该让密码可以解密，而应该总是使用密码的哈希。

当用户登录时，你只需要哈希他们的密码，然后比较哈希，但这应该是一个单向的过程，其中解密不会发生。

这个提示很好地说明了如何做到这一点：密码存储：如何操作。 [ ^ ]

You should never make a password decryptable, but rather you should always use a hash of the password.
When a user logs in, you simply hash their password and then compare the hashes, but this should be a one-way process where decryption cannot happen.
This tip shows very well how to do this: Password Storage: How to do it.[^]

HI，



这是一个你可以解决的解决方案e用于解密密码。

Here is a solution that you can use for the decription of password.

/// <summary>
       /// This function is  used for the decription of the password.
       /// </summary>
       /// <param name="stringToDecrypt"></param>
       /// <returns></returns>
        public static string Decrypt(string stringToDecrypt)
        {
            MemoryStream ms = null;
            byte[] inputByteArray = new byte[stringToDecrypt.Length + 1];
            try
            {
                byte[] key = { };
                string sEncryptionKey = "!#

a54？3;
byte [] IV = {18,52,86,120,144,171,205,239};

key = Encoding.UTF8.GetBytes（sEncryptionKey）;
DESCryptoServiceProvider des = new DESCryptoServiceProvider（）;
inputByteArray = Convert.FromBase64String（stringToDecrypt）;
ms = new MemoryStream（）;
CryptoStream cs = new CryptoStream（ms，des.CreateDecryptor（key，IV），CryptoStreamMode.Write）;
cs.Write（inputByteArray，0，inputByteArray.Length）;
cs.FlushFinalBlock（）;
System.Text.Encoding encoding = System.Text.Encoding.UTF8;
返回encoding.GetString（ms.ToArray（））;
}
catch（例外e）
{
return e.Message;
}
最后
{
ms = null;
}
}

a54?3"; byte[] IV = { 18, 52, 86, 120, 144, 171, 205, 239 }; key = Encoding.UTF8.GetBytes(sEncryptionKey); DESCryptoServiceProvider des = new DESCryptoServiceProvider(); inputByteArray = Convert.FromBase64String(stringToDecrypt); ms = new MemoryStream(); CryptoStream cs = new CryptoStream(ms, des.CreateDecryptor(key, IV), CryptoStreamMode.Write); cs.Write(inputByteArray, 0, inputByteArray.Length); cs.FlushFinalBlock(); System.Text.Encoding encoding = System.Text.Encoding.UTF8; return encoding.GetString(ms.ToArray()); } catch (Exception e) { return e.Message; } finally { ms = null; } }

如需使用以下内容：

For encription use the following:

/// <summary>
        /// This function is  used for the encription of the password.
        /// </summary>
        /// <param name="stringToEncrypt">String to encript</param>
        /// <returns></returns>
        public static string Encrypt(string stringToEncrypt)
        {
            MemoryStream ms = null;
            try
            {
                byte[] key = { };
                string sEncryptionKey = "!#
