PeaZip is a free file archiver especially focused on security, which
supports reading and writing (encryption and decryption) of many strong
encryption standards,
optionally using 2FA <span style="font-weight: bold;">two factor
authentication</span> (password and keyfile) for increased security
against means like <span style="font-weight: bold;">social engineering</span>
or <span style="font-weight: bold;">dictionary based attacks </span>(that
can considerably reduce the effort of brute-forcing a textual password
or passphrase).<br>

<br>
<a name="how_to_use_cryptography"></a>Use of end-to-end
cryptography, in which sender and recipient are in
charge of encrypting and decrypting the encoded data, is strongly
recommended
each time sensitive data is sent to (or through) external servers, even
if the
service is advertised implementing cryptography measures.<br>
In example, creating encrypted mail
attachments (and to encrypt uploads to cloud services) preserve
data secrecy against any unauthorized access to user's private
information and data even in case the service is
compromised, either by successful attack, insider breach, or plain
change of policies granting access to unwanted subjects: to <a

file archive (password protect
files within archives), chose an archive type
supporting encryption, as ZIP, 7Z, ARC, PEA, and ZPAQ, add files to the
archive being created as explained in the FAQ page, then click on the
padlock icon to
set a <span style="font-weight: bold;">password </span>and optionally
a <span style="font-weight: bold;">keyfile</span> for the archive -
the icon is in the status bar in the file/archive browser, and under

<h3 style="font-weight: bold;"><big>Encrypt files with two
factor authentication (password and keyfile)<br>
</big></h3>
<br>
<a name="encrypt_with_key_file"></a>PeaZip free encryption
software
supports optional <span style="font-weight: bold;">two factor
authentication</span> (2FA) for any
write-supported archive format (7Z, ARC, PEA, RAR, ZIP) using both a
password (the element you know) and a keyfile (the element you have) to
encrypt the content - it only needs to enter a keyfile in password
dialog when creating the archive.<br>
If a keyfile is set for any
other format than PEA (which has its own way to use keyfile) the SHA256
hash of the file encoded in Base64 (RFC 4648) is prepended to the
password used to build the archive, using standard archive format
encryption mechanism.<br>
This simple password / keyfile combination scheme allows to retain read
compatibility with any other file archiver, even ones not supporting
keyfile parsing (or with different two factor authentication
implementation), simply
passing the Base64-encoded SHA256 hash of the keyfile as the first part
of the password.<br>
