>I have a field in a third-party table with a maximum length of 19-characters which I would like to replace with its encrypted self. The encrypted string is invariably longer than the original...like 25 characters. Am I right in assuming that this encrypted string is compressible, and if so, would someone please advise me on what method I could use to compress a string? I have DynaZip, but I've only just strted playing with it.

Hi John,

It depends on what level of encription you need. For basic encryption you can use VFP implementation of the Chipher encryption FAQ #27613 which doesn't change length of the encoded string.
