Author crypting files

Hello,

I would like to ask as to what is the best way to encrypt files in
unix. I somehow started by tar then compress then using the crypt
command to encrypt them. Is there a better solution around there?

There are many ways to encrypt files. The 'crypt' command is fairly
weak.

A popular solution is GnuPG, which in addition to the public/private key
architecture it's best known for can also do simple symmetric
encryption. If you're using Linux, this is probably already installed
on your system.

You can actually use the 'openssl' command to encrypt and decrypt
files.

A search for "encrypt" on Freshmeat
(http://freshmeat.net/search/?q=encrypt) will reveal a variety of
packages for handling file encryption.

beside, pgp and gpg, there's the openssl command that may be
slightly more likely to be installed on a Unix.

See "man enc" on such systems.

Although weak, the "zip/unzip" commands have an "-e" encryption flag
on most modern Linux systems.

Thanks everyone. I have decided to use pgp.
