Hi all,
     I was wondering if any of you experts out there have an encryption routine or algorithm I can use.  I am trying to
encrypt selected information from an access database to a text file to be compressed and sent over to a remote
computer and decrypted on the remote computer.  Thanks!

Public Function Decrypt(strInput As String, strDefault As String) As String
    Dim i, intAscii, intChar1, intChar2 As Integer
    Dim strTemp As String
   
    If strInput = "" Then
        Decrypt = strDefault
        Exit Function
    End If
   
    strTemp = ""
    For i = 1 To Len(strInput) Step 2
        intAscii = (ConvChar(Mid$(strInput, i, 1)) * 16) + ConvChar(Mid$(strInput, i + 1, 1)) - 13
        If intAscii < 0 Then intAscii = intAscii + 255
        strTemp = strTemp + Chr(intAscii)
    Next i
   
    Decrypt = strTemp
End Function

Public Function ConvChar(strInput As String) As Integer
    Select Case strInput
        Case "A"
            ConvChar = 10
            Exit Function
        Case "B"
            ConvChar = 11
            Exit Function
        Case "C"
            ConvChar = 12

        Case "E"
            ConvChar = 14
