OS-portable archival software offering flexible security options and authenticated encryption

Free cross-platform file archival software, provides unified graphical user interface frontend for Open Source technologies like 7-Zip (powerful, state of art file compressor), FreeArc (innovative high efficient compression and encryption project), PAQ family (multiple times Hutter prize winner), UPX (compression of executables)... The software supports handling over 150 archive types - including mainstream formats like .7Z, .CAB, .ISO, .RAR, .TAR, .ZIP, .ZIPX - alongside its native .PEA file format offering flexible security options (up to AES-EAX authenticated encryption), deflate based compression, and multi-volume spanning. Features of PeaZip includes creating self extracting archives, strong encryption (optional two factor authentication and encrypted password manager), secure data deletion (files and free space), identify duplicate files, verify checksum and hashes. The program can export task definition as command line, in order to allow thorough inspection (for learning, or other purpose) or usage in scripts. PeaZip is available as installable package and in Portable form, which does not need to be installed (not requiring administrative rights to enable a machine to use the software) and can be simply saved on desired path, in example USB flash drive, removable disk, shared LAN unit, or cloud service.
