You really should demonstrate that have spent at least 30 seconds trying to help yourself by using a search engine. > The basic functions I needed are: > - (Important) Higher compression ratio Linux Journal reviewed compression tools in issue 137: http://www.linuxjournal.com/article/8051, which would probably be helpful to you.

An integrated tool like that would go against the unix philosophy of separating concerns. It limits your options. The two standard tools to create archives are cpio and tar. > - (optional) GPG signature & encryption Again, you would use an external tool (gpg) for that. You now need to decide if you want to sign the whole archive, or each volume. Make sure you encrypt after you compress. > - (optional) Password protected zip supports passwords on archives, and if I recall correctly they were trivial to break. You are better off with gpg, but it will take a while. If you just need integrity check use sha1 (or md5) sums instead. > It would be great if I could just apt-get it. Start by reviewing this list then: `apt-cache search archive | egrep -v ^lib` /Allan
