  • extract/browse only support: Z
As Pea-Peach, PeaZip is released under LGPL and the Pea file format specifications remain under PUBLIC DOMAIN.


Special thanks goes to:
  • Wolfgang Ehrhardt who written and maintains a very good Delphi/Pascal crypto library, used in PeaZip and in PEA file format, you can find his works on: http://home.netsurf.de/wolfgang.ehrhardt/index.html please refer to Wolfgang Ehrhardt for all what concerns those units, (collected in "we" path in PeaZip source package).
  • Igor Pavlov for providing under LGPL license his excellent 7Zip archiver, used in PeaZip (as 7za standalone console executable) to support most of mainstream file formats, along with all people developing and mantaining POSIX version of 7Zip, p7Zip. Please refer to 7Zip/p7Zip Authors for all what concerns 7za binaries, on http://www.7-zip.org and http://p7zip.sourceforge.net/
  • All people on sci.crypt.* and comp.compression, for the useful answers and information provided during PEA format development.
  • Wikipedia, for the quality of the articles and links provided.
  • FreePascal and Lazarus teams, for developing and maintaining such a good development environment and related documentation.
  • Tango Desktop Project team, for releasing under Creative Commons Attribution Share-Alike license many very nice looking icons, used in PeaZip Interface.

last update 0.12 2006 09 28

Pea is a new archive format, focused on offering flexible and advanced security and integrity check features; pea file format specifications are released under PUBLIC DOMAIN.
Pea executable is the implementation of an archiver application supporting pea file format natively:
it takes files, folders and volumes as input and archives it in volumes of given sizes, supporting various integrity checks (default: CRC64), hashes (default: SHA256) and up to AES 256 in EAX mode authenticated encryption.
Pea executable is fully graphic; it can be invoked by command line and can be compiled a a library to easily use it from third parts applications, otherwise can be invoked by Peach graphic frontend.
Pea and Peach are implemented in FreePascal language and the sourcecode is released under LGPL.
The applications are free for download and distribution.
