AES-256 encrypted zip files are the only reason I use 7z from the command line instead of File Roller. File roller should at least tell you what encryption it is using. The original .zip encryption is a joke by today's standards. I had to install 7z just to figure out what encryption file-roller/zip was actually using (AES-128 on Ubuntu 12.04).
Here is a short script for running 7z with AES-256 without typing your password on the command line (and thus entering it into the history):
read -s -p "Please enter a password: " backup_pass
backup_pass="'"$backup_pass"'"
7z a -tzip -p$password -mem=AES256 destFile.zip folderOrFileName
