PeaZip is focused on security and supports handling multiple strong encryption
standards for archives:
encryption / decryption support
7-Zip AES-256 encryption
AES-256, Blowfish, Serpent-256,
This format also supports recovery records to protect data
EAX mode authenticated encryption
WinZip AE, based on AES-256
ZipCrypto (for legacy
RAR5 AES-256 in CBC mode
AES encryption standard
|Hint: official PeaZip packages NEVER
ask users a password to be installed or to run: if that happens please
trust that package and rely only on official packages published on
official PeaZip domain, and official mirrors.
To extract a
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.
revisions of mainstream archive formats like (7Z, ARC, PEA,
RAR, and ZIP/ZIPX) uses strong file encryption, and it is unlikely to
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 not because it is encoded but because
corrupted or was created 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.
