Using a salt value
Hi,
I've been reading up on using a salt value when creating a password to make it more secure, what I can't get my head round is how do you remember this salt value?
I'm guessing that when a user logs in to be able to compare the password entered with the one in the database you would need to again add the salt value to the entered password.
Am I missing something really obvious?
Thanks in Advance

ns_crypt
ns_crypt(3aolserver) AOLserver Built-In Commands ns_crypt(3aolserver)
__________________________________________________________________________________________________________________________________________________
NAME
ns_crypt - commands
SYNOPSIS
ns_crypt key salt
_________________________________________________________________
DESCRIPTION
ns_crypt encrypted the key, also known as the password, using the salt and returns the result. It uses the same algorithm as the unix
crypt command.
The result from ns_crypt is a 13-character string. The first two characters correspond to the salt, and the remaining eleven characters
correspond to the password encrypted with the specified salt.
The password is a string (typically that of a password to be used for nscp and/or nsperm authentication).
salt should be two characters, typically from the set [a-zA-Z0-9./]. If the empty string is specified as the salt then ns_crypt returns
the empty string. If a string longer than two characters is specified for the salt it is truncated to two characters. If a one character
salt is provided the output will appear to have a two-character salt (the single character repeated), however, the encrypted value does not
correspond to the same password being encrypted with the equivalent two character salt. (As a result sticking with a two character salt is
highly recommended.)
Input to ns_crypt is case-sensitive.
