VFP_B32

Description

VFP_B32 is a RFC 3548 Base32 String Decoder and Encoder for Visual FoxPro encapsulated in a simple to use class. The code was adapted from the Javascript implementation of [Thirty-Two] (https://github.com/chrisumbel/thirty-two) by Chris Umbel.

Some examples / How to use

  loBase32 = NewObject("VFP_B32", "vfp_b32.prg")
  ** Encode a String in BASE32
  lcEncodedString = loBase32.Encode("Hello world!")
  ? lcEncodedString
  ** Decode the Base32 string
  lcDecodedString = loBase32.Decode("JBSWY3DPEB3W64TMMQQQ=")
  ? lcDecodedString

About this Program

This program has was written for Visual FoxPro 9. As some VFP specific functions are used (like ALINES) it might not run in older Foxpro Versions.

Function Encode

Parameters: Takes a string as parameter which needs to be encoded into Base32 Return: a Base32 encoded String

Usage:

  loBase32 = NewObject("VFP_B32", "vfp_b32.prg")
  ** Encode a String in BASE32
  ? loBase32.Encode("Hello world!")

Function Decode

Parameters: Takes a string as parameter (the Base32 encoded one) Return: Decoded Base32 string - If any errors occured or the string is not a valid Base32 String, an empty string is returned!

Usage:

  loBase32 = NewObject("VFP_B32", "vfp_b32.prg")
  ** Decode the Base32 string
  ? loBase32.Decode("JBSWY3DPEB3W64TMMQQQ=")

If you like this...

..i would be happy, if you give this repository a star if it was helping you! Thanks. If you have time and love older FoxPro versions, feel free to make a Commit and PR to adapt this code to maybe FoxPro Version before 9 and 8.
