Description:

HS-HASH is a data hashing class that uses a secure hash algorithm and returns the hashed value of the entered string.

Article:

HS-HASH is a data hashing class that uses a secure hash algorithm and returns the hashed value of the entered string. For security reasons, you may want to store passwords in hashed form. This guards against the possibility that someone who gains unauthorized access to the database can retrieve the passwords of every user in the system. Hashing performs a one-way transformation on a password, turning the password into another String, called the hashed password. “One-way” means that it is practically impossible to go the other way - to turn the hashed password back into the original password.
 

Here is some code on how to use HS-HASH

How to hash a string:

private void Button_Click(object sender, RoutedEventArgs e)
        {
            // Hash options
            // string hash = Hash1.Get_MD5_Hash(tbStringToHash.Text);
            // string hash = Hash1.Get_SHA1_Hash(tbStringToHash.Text);
            // string hash = Hash1.Get_SHA256_Hash(tbStringToHash.Text);
            // string hash = Hash1.Get_SHA384_Hash(tbStringToHash.Text);
            string hash = Hash1.Get_SHA512_Hash(tbStringToHash.Text);
            tbHash.Text = hash;
        }

How to verify a hash

private void Button_Click_1(object sender, RoutedEventArgs e)
        {
            // Verify hash options
            // Hash1.Verify_MD5_Hash(tbStringToHash.Text, tbHash.Text)
            // Hash1.Verify_SHA1_Hash(tbStringToHash.Text, tbHash.Text)
            // Hash1.Verify_SHA256_Hash(tbStringToHash.Text, tbHash.Text)
            // Hash1.Verify_SHA384_Hash(tbStringToHash.Text, tbHash.Text)
            // Hash1.Verify_SHA512_Hash(tbStringToHash.Text, tbHash.Text)

            // Verify the hash
            if (Hash1.Verify_SHA512_Hash(tbStringToHash.Text, tbHash.Text) == true)
            {
                MessageBox.Show("Good Password");
            }
            else
            {
                MessageBox.Show("Bad Password");
            }
        }
