FAQ: Open and extract password protected
archives

How extract encrypted archive files with PeaZip?
standards:- 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
Some archive formats, like 7Z, ARC and RAR, supports encrypting the list of files and folders contained in the archive, to protect this information from unauthorized users, so the password will be required even for listing or browsing the archive.
In other cases it is possible to browse the password protected archive, but the password will be required to extract files; in PeaZip's 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.
Hint:
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.
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
chosing if entering a password
for trying to decrypt the archive, even if the file extension is
not
usually associated with archives supporting encryption (as it can be
easily changed).Hint: 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.
PeaZip 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.
If you got a corrupted archive you will need to re-download it from a trusted source or restore it from a backup copy.
