Full Discussion: "SCRYPT" command in RED HAT 9
Operating Systems Linux Red Hat "SCRYPT" command in RED HAT 9 Post 302267706 by Perderabo on Saturday 13th of December 2008 01:26:41 PM

crypt is a very weak encryption program that should no longer be used. This was actually true 25 years ago. At this point, crypt is sadly obsolete. You need a strong encryption algorithm and one of the best currently available is AES-256. No one has broken it yet. The US government currently allows the use of AES-256 to protect Top Secret information.

I suggest that you use gpg to encrypt your file, but you must specify the encryption algorithm like this:

gpg -c --cipher-algo aes256 secret.txt

and to decrypt the file:

gpg secret.txt.gpg


GNU Privacy Guard, gpg, seems to simply come with our Linux systems. It is available on sunfreeware.com for Solaris. I also found a package for XP at the The GNU Privacy Guard - GnuPG.org site (navigate to the download page).

dircproxy-crypt

dircproxy-crypt(1)					      General Commands Manual						dircproxy-crypt(1)

NAME

       dircproxy-crypt - Generate encrypted password for dircproxy

SYNOPSIS

       dircproxy-crypt [-hv] [password]...

DESCRIPTION

       dircproxy-crypt generates encrypted passwords for the dircproxy(1) configuration file.  These passwords are used in the 'password' configu-
       ration option of a connection class, and are compared to the password you configure your IRC client to use.

       If you do not supply any plain text passwords to encrypt on the command line then dircproxy-crypt, when run, will ask you for one on  stan-
       dard  input.   It  will display the encrypted version of each password, created using your system's crypt(3) function and a random salt, on
       standard output.

OPTIONS

       -h     Displays a brief help message detailing the command-line arguments, then exits.

       -v     Displays the dircproxy version number that this version of dircproxy-crypt comes with, then exits.
