Keka is capable of compressing Zip files using AES cypher. By default it uses Zip Legacy 2.0, since is the most supported on all systems.

The Zip 2.0 (Legacy) encryption format is supported by nearly all other Zip file utilities. Password protecting a Zip file with Zip 2.0 encryption provides a measure of protection against a casual user who does not have the password and is trying to determine the contents of the files. However, the Zip 2.0 encryption format is known to be relatively weak, and cannot be expected to provide protection from individuals with access to specialized password recovery tools.

Do not rely on Zip 2.0 encryption to provide strong data security.
