Hi peter, i'm not aware of all file formats but you should stick with PKCS#12 format for symmetric encryption. It's an open standard, so I'm sure openssl and windows encryption can handle it. Gnugp uses OpenPGP file formats.

At the moment I don't encrypt them - I don't understand encryption and I'm nervous of using something I don't understand. They're just family snaps, but I'd prefer they stayed private. Symmetric encryption seems a good route - all I have to remember is a single password (the only risk seems to be senility). However, who knows what OS or tools I'll be using in the future? I ran a few tests encrypting and decrypting using the same algorithm/password but different tools (gpg, openssl, mcrypt). They were unsuccessful. My question is do I always have to use the same tool to decrypt as I used to encrypt? Are the file formats tool specific? Is the way the tool derives a key from the "key" I input variable? Probably there are other issues I'm unaware of. I'd feel more comfortable knowing that recovery of my data wasn't dependent on the availability of a specific tool (or even worse a specific version of a tool). Hope this is clear, Thanks _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
