[nanakofiboafo]

how do i hash from plaintext to ciphertext in visual basic 6.0. I want to hash from the plaintext before i save it in the database and hash from ciphertext to plaintext before logining in. I need your help.

Hello , You can use the 'String.GetHashCode' function to get a hash for a string's. and also Check this link http://www.di-mgt.com.au/cryptoBlowfishDemo.html

Why don't you go something like this code? It should work on your side as it does on my computer.

Public Function Encode(ByVal plaintext As String)
        Dim ciphertext As String
        Dim magic_buffer As String
        Dim ctc As String
        Dim magic_number As Long
        Dim length As Long
        Dim count As Long
        Dim mncount As Long
        Dim ptc As Long
        Dim baz As Long
        Dim foo As Long
        Dim bar As Long
        magic_buffer = "ERGergergerERGergaasa23AWf4"
        length = Len(plaintext)
        magic_number = Int((255 - 0 + 1) * Rnd()) + 0
        ciphertext = Hex(magic_number)
        If magic_number < 16 Then
            ciphertext = "0" & ciphertext
        End If
        count = 0
        mncount = 0
        While count < length
            ptc = Asc(Len(plaintext))
            baz = ptc + magic_number
            If baz > 255 Then
                bar = ptc + 1
                foo = bar + magic_number - 256
            Else
                foo = ptc + magic_number
            End If
            magic_number = foo Xor Asc(Len((magic_buffer)))
            ctc = Hex(foo Xor Asc(Len((magic_buffer))))
            If Len(ctc) = 1 Then
                ctc = "0" + ctc
            End If
            ciphertext = ciphertext + ctc
            count = count + 1
            mncount = mncount + 1
            If mncount > 27 Then
                mncount = 1
            End If
            ciphertext = UCase(ciphertext)
         Wend
        ciphertext = UCase(ciphertext)
        FunctionName = ciphertext
End Function
