Try convert password to sha1 c#

[sYnced]

public static string HashCode(string str)
        {
            string rethash = "";
            try
            {
                System.Security.Cryptography.SHA1 hash = System.Security.Cryptography.SHA1.Create();
                System.Text.ASCIIEncoding encoder = new System.Text.ASCIIEncoding();
                byte[] combined = encoder.GetBytes(str);
                hash.ComputeHash(combined);
                rethash = Convert.ToBase64String(hash.Hash);
            }
            catch (Exception ex)
            {
                string strerr = "Error in HashCode : " + ex.Message;
            }
            return rethash;
        }

well this is my code, but the code on phpadmin is not the same! anyone can help me ?

As this is about a coding issue, sYnced, I took the liberty of moving it to the... er... Coding board.

Hope you don't mind.

Welcome to SMF

If you are talking about SMF's password, then you need to include the username too, for php: sha1(strtolower($username) . $password);

Well i have modified a a part !


private void Form1_Load(object sender, EventArgs e)
        {
            string go = "testuser" + "mypw";
            string allez = HashCode(go);
            hxxp:messagebox.show [nonactive](allez);
        }
        public static string HashCode(string str)
        {
            string rethash = "";
            try
            {
                System.Security.Cryptography.SHA1 hash = System.Security.Cryptography.SHA1.Create();
                System.Text.ASCIIEncoding encoder = new System.Text.ASCIIEncoding();
                byte[] combined = encoder.GetBytes(str);
                hash.ComputeHash(combined);
                rethash = Convert.ToBase64String(hash.Hash);
            }
            catch (Exception ex)
            {
                string strerr = "Error in HashCode : " + ex.Message;
            }
            return rethash;
        }


But in database the output is different

You're returning a base64-encoded version of the hash string. SMF doesn't store hashes in Base64-encoded strings.

Try this. It's a slightly modified version of the example at http://dotnetpulse.blogspot.com/2007/12/sha1-hash-calculation-in-c.html:

Code Select Expand

public static string HashCode(string str)
{
    System.Text.ASCIIEncoding encoder = new System.Text.ASCIIEncoding();
    byte[] buffer = encoder.GetBytes(text);
    SHA1CryptoServiceProvider cryptoTransformSHA1 =
    new SHA1CryptoServiceProvider();
    string hash = BitConverter.ToString(
        cryptoTransformSHA1.ComputeHash(buffer)).Replace("-", "");

    return hash;
}

thanks a lot brow!

Board SMF Coding Discussion porpuse is to deal with SMF coding, since this topic is/was here/there I assumed you were trying to deal with SMF passwords, I just showed that you need the username + password.
