How to encrypt a blob?
-
I need to "encrypt on save" and "decrypt on retrieve" office files stored as blobs in the database (SQL 2000). So far - found only one thread on this site with some ideas:

Please help!

This may not help, but in the past I have written applications that needed to compress the files stored in blobs. I had the client do it using ZIP (the old command line one that could be shelled out to).
How are these retrieved? If it is only from your custom client application, then why not do it there? You can use whatever encryption method you want then, even zip with password.
