Hàm mã hóa mật khẩu md5 trong ASP.NET MVC viết như thế nào ạ?

1. Khai báo thư viện:

using System.Security.Cryptography;

2. Mã hóa mật khẩu:

public static string EncodePassword(string originalPassword)
{
    //Declarations
    Byte[] originalBytes;
    Byte[] encodedBytes;
    MD5 md5;

    //Instantiate MD5CryptoServiceProvider, get bytes for original password and compute hash (encoded password)
    md5 = new MD5CryptoServiceProvider();
    originalBytes = ASCIIEncoding.Default.GetBytes(originalPassword);
    encodedBytes = md5.ComputeHash(originalBytes);

    //Convert encoded bytes back to a 'readable' string
    return BitConverter.ToString(encodedBytes);
}

public static string CreateMD5(string input)
{
    // Use input string to calculate MD5 hash
    MD5 md5 = System.Security.Cryptography.MD5.Create();
    byte[] inputBytes = System.Text.Encoding.ASCII.GetBytes(input);
    byte[] hashBytes = md5.ComputeHash(inputBytes);

    // Convert the byte array to hexadecimal string
    StringBuilder sb = new StringBuilder();
    for (int i = 0; i < hashBytes.Length; i++)
    {
        sb.Append(hashBytes[i].ToString("X2"));
    }
    return sb.ToString();
}
