Encrypting Data

[Auguy]

I was just notified of the need to encrypt the data used in a financial application I wrote a few years ago in 6.0. I took a quick look at Cryptor, Sweet Potato Software, and Encryption File System (EFS). I'm not sure I can use EFS because I'm Not entirely sure they are using a "Real" server. Because this app is already written I'm leaning towards whole file/folder encryption rather than field by field to minimize code change. I've read a few of the posts on this forum to try and get a feel for what to use and was wondering what the current outlook on encryption is. I could recompile into 9.0 if that would help any. Does anybody have any recommendations or pitfalls to watch for? Potential costs/coe changes?

File/Folder doesn't work. First person into the app must decrypt the file. That means it's now visible to everyone.

Auguy,

I believe Cryptor allows you to keep entire files encrypted on disk, and just decrypt them on the fly. But I only have hear-say evidence for that; I've never used it myself.

Thanks to all for your information. Mike, that is my understanding on Cryptor too. By the way, did you ever make it to Ohio this year?

Not quite. I tried to plan the trip three times, but more urgent things always got in the way. I'll maybe do it in first quarter of 2010.
