PeaZip is focused on security and supports multiple strong encryption standards,
optionally using two factor
authentication (password and keyfile *) for increased security
against means like social engineering
or dictionary based attacks that
can considerably reduce the effort of brute-forcing a textual password
or passphrase.
Encryption standards supported by PeaZip are:
- 7Z's AES256 encryption
- ZIP WinZip's AE encryption based on AES256 (and
ZipCrypto for legacy compatibility); can decrypt PKZip's AES encryption
- FreeARC's ARC: AES256, Blowfish, Twofish256 and
Serpent256; this format also supports recovery records to protect data
against corruption
- PEA: AES256 EAX authenticated encryption
To password protect files within archives, chose an archive type
supporting encryption, as ZIP, 7Z, ARC, and PEA, add files to the
archive being created as explained in the FAQ page, then click on the
locker icon  to
set a password and optionally
a keyfile * for the archive -
the icon is in the status bar in the file/archive browser, and under
the output file name in the archive creation interface.
PeaZip software also provides an encrypted
password manager in Tools > Password manager from main menu,
in this way a master password can be used to encrypt passwords the user
desires to keep saved.
The password manager file is unique for each user on the system using
PeaZip, so multiple users can keep multiple separated password lists.
Some archive types, like 7Z and ARC, support encrypting the names of
files being added to the archive: in this case it will not even be
possible to see the list of archive's content, file and directory
names, without knowing the password.
7Z, ARC, and ZIP archives support file level encryption, so each file
in an archive could have, if desired by the archive creator, a
different password.
In "Advanced" tab of archive creation interface users can chose
encryption method to apply to the archive: by default the recommended
method will be displayed.
If a password is already set (i.e. because adding files to an already
encrypted existing archive) it will be reported to the user in the
archive creation interface.
* PeaZip has an integrated utility to create
random keyfiles and
passwords sampling entropy from the system and from user's
interaction.
