    You forgot to say: scrypt

    # apt-cache show scrypt
    " Package: scrypt
    Version: 1.1.6-3
    [...]
    Description-en: File encryption utility using scrypt for key derivation
    A simple password-based encryption utility which demonstrates the
    scrypt key derivation function.  On modern hardware and with default
    parameters, the cost of cracking the password on a file encrypted by
    scrypt enc is approximately 100 billion times more than the cost of
    cracking the same password on a file encrypted by openssl enc; this
    means that a five-character password using scrypt is stronger than a
    ten-character password using openssl.

    If we encrypt a file using the command “gpg -c filename” and use cat command to check the content, we cannot see the content without a password.

    But if we use less command we can see the content. Then what is the use of it?

    Hi. The 3rd tool, Ccrypt, has a typo, to decrypt a file it’s ccdecrypt instead decrypt

    Hey Ya people!

    This is funny.

    It should be different and way way different.

    How do we prevent somebody to copy files from our PC while we are on the Internet!

    Emacs users can also use EasyPG which allows to encrypt/decrypt files with the extension .gpg
    EasyPG can either use an existing GPG key or a standalone password (i.e. symmetric encryption).

      @Stephane,

      Thanks for the tip about EasyPG tool, never heard of this too so far, will certainly give a try right away…

    That’s not 7 tools LOL.. You’re talking about integration using the same tools gezzzzzzzzzz

  7. Kyle Lewis says:

    The article refers to bcrypt as “a key derivation function.” This shows that the author has confused bcrypt the key derivation (hash) function with bcrypt the command-line encryption program. These are two different things.

    It is true that bcrypt the hash function has been found to have weaknesses of some concern. The author’s remarks about bcrypt being unsafe however do NOT apply to bcrypt the command-line encryption program.

    • Inversion says:

      Yeah the article is completely wrong. Stating 7 when they’re using integration which uses same tools. Bad article is you ask me.

    Excellent collection, thank you very much .

    Great collection!
    Thanks!!! :-)

    One useful addition, (at my opinion) is Veracrypt (Truecrypt successor).
    https://sourceforge.net/projects/veracrypt/

    Comes with an installer and it has a console and a gui version.
    Also with Windows and OSX versions.
