Hi guys,

I have a central server that runs encryption to secure the file contents. On occasion, an authorised user may request the server copy archived files to his/her computer for local manipulation.

My VB program which receives the file copy request duly copies down to the user's computer the files requested, but they are still encrypted! (Therefore the user cannot open or delete or move them).

What are my options for ensuring the files are decrypted when they arrive on the user's computer? The encryption was applied on the central server - so the central server has to decrypt the files before delivery.

For some (wrong) reason, I thought that if encrypted files were copied to somewhere, they'd be decrypted. This is obviously not the case!

Note that the user's computer is running NTFS. Perhaps changing the user's file system to FAT32 would help? Is there a switch on the "copyfile" API to decrypt files on copy?

Help appreciated!

Mark
