Re: [Trisquel-users] archive file formats

[onpon4]

Zip uses the same algorithm as Gzip, DEFLATE. The main difference is Zip uses  
it individually on each file, whereas Gzip uses it on the entire archive  
collectively, making Gzip better. I don't think there's really a good reason  
to use Zip, except to give something to a Windows user (since Windows only  
supports Zip archives out-of-the-box).

For password protection, as far as I know the best choice is 7-zip. Install  
the p7zip package to get full support for that format. The 7-zip format  
encrypts archives with the strongest form of AES, which from my understanding  
is OK (the U.S. government trusts it for top-secret stuff, for instance).
