What commands can be used to replace crypt???
crypt is a command that is used to add more security to files.
now, this crypt command is used on systems (i dont know which) other that Linux RedHat
now, my question is that is there a command in Linux Red Hat similar to the crypt command???
i really want to have the files on my system extra extra extra secure. This crypt command has methods that can be used to lock down important files to the point that even certified hackers cant see its content.
now, theres goto be a similar command on Linux, anyone knows this???

crypt.conf
crypt.conf(4) File Formats crypt.conf(4)
NAME
crypt.conf - configuration file for pluggable crypt modules
SYNOPSIS
/etc/security/crypt.conf
DESCRIPTION
crypt.conf is the configuration file for the pluggable crypt architecture. Each crypt module must provide a function to generate a pass-
word hash, crypt_genhash_impl(3C), and a function to generate the salt, crypt_gensalt_impl(3C).
There must be at least one entry in crypt.conf with the same name as is stored in the crypt_algorithm_magic symbol of the module. The docu-
mentation provided with the module should list this name.
The module_path field specifies the path name to a shared library object that implements crypt_genhash_impl(), crypt_gensalt_impl(), and
crypt_algorithm_magic. If the path name is not absolute, it is assumed to be relative to /usr/lib/security/$ISA. If the path name con-
tains the $ISA token, the token is replaced by an implementation-defined directory name that defines the path relative to the calling pro-
gram's instruction set architecture.
The params field is used to pass module-specific options to the shared objects. See crypt_genhash_impl(3C) and crypt_gensalt_impl(3C). It
is the responsibility of the module to parse and interpret the options. The params field can be used by the modules to turn on debugging
or to pass any module-specific parameters that control the output of the hashing algorithm.
EXAMPLES
Example 1: Provide compatibility for md5crypt-generated passwords.
The default configuration preserves previous Solaris behavior while adding compatibility for md5crypt-generated passwords as provided on
some BSD and Linux systems.
#
# crypt.conf
#
1 /usr/lib/security/$ISA/crypt_bsdmd5.so
Example 2: Use md5crypt to demonstrate compatibility with BSD- and Linux-based systems.
The following example lists 4 algorithms and demonstrates how compatibility with BSD- and Linux-based systems using md5crypt is made avail-
able, using the algorithm names 1 and 2.
#
# crypt.conf
#
md5 /usr/lib/security/$ISA/crypt_md5.so
rot13 /usr/lib/security/$ISA/crypt_rot13.so
# For *BSD/Linux compatibilty
# 1 is md5, 2 is Blowfish
1 /usr/lib/security/$ISA/crypt_bsdmd5.so
2 /usr/lib/security/$ISA/crypt_bsdbf.so
