PeaZip is focused on
security and supports multiple
- 7Z 7-Zip'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
- PEA: AES256 EAX authenticated encryption
official PeaZip packages NEVER
asks users a password to be installed: if that happens please don't
trust that package and rely only on official packages published on
peazip.org. and official mirrors.
To extract a password
protected archive open it with PeaZip (double click if it is a
supported file extension) to read and navigate/search its content, then
use Extract button in application's toolbar.
Otherwise, use "Extract" entries in context menu for direct extraction
without browsing the encrypted container.
If a password is needed for
extraction (or browsing) PeaZip will prompt a form to enter the
password or passphrase (and
optionally a keyfile, if two factor authentication is in use).
Some archive formats, like 7Z, ARC and RAR, supports encrypting the
list of files and folders contained in the archive (option usually
identified as "encrypt file names
to protect this
information from unauthorized users, so the password will be required
even for listing / browsing the archive.
In other cases it is possible to browse the password protected archive,
but the password will be required to extract the encrypted data; in
file/archive browser you can enter the password clicking the proper
context menu entry or clicking on the locker icon in the status bar
or pressing F9.
Current revisions of mainstream archive formats like (7Z, ARC, PEA,
RAR, and ZIP) uses strong file encryption, and it is unlikely to be
possible to brute-force it with any kind of utility if the password is
unknown or was forgotten.
In some cases PeaZip may not
able to browse archive's content because
corrupted or out of standard: in all
those cases PeaZip
will always display the password dialog, to let the user in control of
choosing if entering a password
for trying to decrypt the archive, even if the file extension is
usually associated with archives supporting encryption, as file
extension can be
If you got a corrupted archive you will need to
re-download it from a trusted source or restore it from a backup copy.
if you have to work on different
archives with the same password you will not need to re-enter it since
it will be kept until you change it or close PeaZip. If you open
different instances of PeaZip each will start with no password and can
keep a different password.
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.
