well, my simple copy paste of your class, and a button to call it returns an error form vb.net;

All i wanted was a string and it's encrypted value, with a certain passphrase, so i could test DES and DES Triple to see if it's the same algrythm, but you poasted code.

I did what i could with your code, but it doesn't work for me.

Private Sub btnTestEncryption_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnTestEncryption.Click

Dim s As String = "Encryption Test"

Dim p As String = "Secret Password"

Dim r As String = EncryptDecrypt.Encrypt(s, p)

Debug.Print(r)

Dim t As String = EncryptDecrypt.Decrypt(r, p)

Debug.Print(t)

MsgBox("Done.")

End Sub
