How do I go about creating a windows application that converts strings to sha1 encrypted? All I want this program to do is have a user type in their password, click a command button "Convert" and have a label come up with the now SHA1 encrypted string. NOTE: THis is just for my own personal use, I will be in no way distributing or selling this program.

SHA1 is an algorithm (Secure Hash Algorithm version 1.0) for encrpyting strings.

Wow, that is some reading.

From a quick glance, I am guessing you will need to use RegEx for managing Regular Expressions.
Not sure I can be much help? :cry: Anyone else? Tekmaven?

Thanks! My hardware should be arriving this week which means an article on forms authentication is due.

I can't understand why my code wont work. Check it out.
The encoding part wont work and when I hover over it it says. "Name 'Encoding' is not declared." any ideas? Maybe I'm missing a library reference?
Imports SHA1_Encryption Imports System.Security.Cryptography PublicClass Form1 Inherits System.Windows.Forms.Form (Windows for designer generated code) PublicFunction ComputeHashValue(ByVal data() AsByte) AsByte() Dim hashAlg As SHA1 = SHA1.Create() Dim hashvalue() AsByte = hashAlg.ComputeHash(data) Return hashvalue EndFunction PrivateSub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim test AsByte() test = ComputeHashValue(Encoding.ASCII.Text(TextBox1.Text)) EndSub EndClass

OK I would still like to get the windows encryption working (above) but I have finished a web application one for now:
Imports System.Web.Security PrivateSub btnProcess_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnProcess.Click Dim encpass AsString = FormsAuthentication.HashPasswordForStoringInConfigFile(txtPassword.Text, "sha1") lblResult.Text = encpass.ToString() EndSub
