create a password in csharp

Here's an example of creating a hashed password in C# using the SHA256 algorithm:


main.cs
using System;
using System.Security.Cryptography;
using System.Text;

public static string HashPassword(string password)
{
    byte[] salt = new byte[16];
    using (var rng = RandomNumberGenerator.Create())
    {
        rng.GetBytes(salt);
    }

    byte[] hashedPassword = HashPasswordWithSalt(Encoding.UTF8.GetBytes(password), salt, 10000, 32);

    return $"{Convert.ToBase64String(salt)}:{Convert.ToBase64String(hashedPassword)}";
}

private static byte[] HashPasswordWithSalt(byte[] password, byte[] salt, int iterations, int hashLength)
{
    using (var pbkdf2 = new Rfc2898DeriveBytes(password, salt, iterations, HashAlgorithmName.SHA256))
    {
        return pbkdf2.GetBytes(hashLength);
    }
}
708 chars
25 lines

To use this method, simply call HashPassword("plaintextpassword") and it will return a string in the format of "base64salt:base64hashedpassword". To verify a password, you would need to store the salt used for that password and then hash the entered password with that salt and compare the result with the stored hashed password.
