Cipher50 is a VFP 5.0 FLL for encrypting character strings and memo fields. It was originally put into the public domain by Tom Rettig Associates in 1991 and has been re-produced by different parties as newer versions of FoxPro have been released. This particular version is tight and fast (only 6k in size), and has been tested on memo fields well over 150,000 characters with blazing speed.
