When encrypting to a *.7z file, 7-zip uses AES-256 in CBC mode, with a
passphrase-to-key function based on SHA-256. This is actually stronger
than most cipher preferences on OpenPGP keys. It is not the same as
the weak "winZip"-derived encryption. Of course, these files can only
be read by 7-zip, but it is free and open source. (It also compresses
a lot better than standard ZIP's DEFLATE algoritm, if more slowly).
