Encryption software flaw

I've run into a problem:

When i encrypt a file using one program, it's the only program that will decrypt it- even if I have the correct algorithm and key.

For instance:

I use ozmiff top encrypt file (A) with twofish and key: T35tin6

I then attempt to decrypt using File encyptor with alorithm twofish and key T35tin6


I get the following error:

File is already decrypted.


i've tried using other SW combos and get the same error. since I xfer date between machines that might not have the same software, how can i get around this other than carrying a standalone encryption program with me?

I've also had this problem when xfering data between machines/users. Do both users have to communicate what SW to use? It seems that given the algorithm and key the SW should be able to be forced to process the file... I have old fuiles that were encrypted using lost SW. I recall the algorithm and key, however


does anyone know how to address this?

most encryption programs require that you use the same program for encrypting and decrypting.
