PeaZip supports a wide range of compression and encryption standard, from fastest to most powerful ones, and allows to export job definition as scripts to bridge the gap between GUI and console applications. PeaZip has secure deletion feature, can verify file checksum and hash, and supports multiple strong encryption standards, optionally using two factor authentication (password and keyfile) for increased security.
