如何获得FormsAuthentication.HashPasswordForStoringInConfigFile("asdf","MD5")方法的相等哈希？

Question

寻找一个方法或指向正确的方向,这样我就可以返回一个等于返回的哈希的哈希值FormsAuthentication.HashPasswordForStoringInConfigFile("asdf", "MD5").我一直在尝试代码:

        ASCIIEncoding encoding = new ASCIIEncoding();
        encoding.GetBytes("asdf");

        var hashedBytes = MD5.Create().ComputeHash(bytes);
        var password = encoding.GetString(hashedBytes);

我对Hashing并不那么强大,所以我不知道下一步该去哪里.我总是以疯狂的特殊字符结束,而FormsAuth方法总是返回可读的东西.

只是尝试从一些内部业务类中删除对FormAuthentication的外部依赖项.

这是反射器的输出:

您的问题不是使用UTF8

public static string HashPasswordForStoringInConfigFile(string password, string passwordFormat)
{
    HashAlgorithm algorithm;
    if (password == null)
    {
        throw new ArgumentNullException("password");
    }
    if (passwordFormat == null)
    {
        throw new ArgumentNullException("passwordFormat");
    }
    if (StringUtil.EqualsIgnoreCase(passwordFormat, "sha1"))
    {
        algorithm = SHA1.Create();
    }
    else
    {
        if (!StringUtil.EqualsIgnoreCase(passwordFormat, "md5"))
        {
            throw new ArgumentException(SR.GetString("InvalidArgumentValue", new object[] { "passwordFormat" }));
        }
        algorithm = MD5.Create();
    }
    return MachineKeySection.ByteArrayToHexString(algorithm.ComputeHash(Encoding.UTF8.GetBytes(password)), 0);
}

所以这是您更新的代码:

    encoding.GetBytes("asdf");

    var hashedBytes = MD5.Create().ComputeHash(bytes);
    var password = Encoding.UTF8.GetString(hashedBytes);

经过一些谷歌搜索,我改变了@ Pieter的代码,使其独立于System.Web

return string.Join("",
  new MD5CryptoServiceProvider().ComputeHash(
    new MemoryStream(Encoding.UTF8.GetBytes(password))).Select(x => x.ToString("X2")));
