Hi guys , in my study book from which I re-learn C is task to generate all possible characters combination from numbers entered by the user. I know this algorithm must use combinatorics to calculate all permutations. Problem is how to implement algortihm.
Author says I must have four nested loops. So as a beginner I must ask for help from experienced programmers.
Hi people,

crypt_unix - traditional UNIX crypt algorithm
DESCRIPTION
The crypt_unix algorithm is the traditional UNIX crypt algorithm. It is not considered sufficiently secure for current systems and is pro-
vided for backwards compatibility. The crypt_sunmd5(5), crypt_bsdmd5(5), or crypt_bsdbf(5) algorithm should be used instead.
The algorithm identifier for policy.conf(4) is __unix__. There is no entry in crypt.conf(4) for this algorithm.
The crypt_unix algorithm is internal to libc and provides the string encoding function used by crypt(3C) when the first character of the
salt is not a "$".
This algorithm is based on a one-way encryption algorithm with variations intended (among other things) to frustrate use of hardware imple-
mentations of a key search. Only the first eight characters of the key passed to crypt() are used with this algorithm; the rest are
silently ignored. The salt is a two-character string chosen from the set [a-zA-Z0-9./]. This string is used to perturb the hashing algo-
rithm in one of 4096 different ways.
The maximum password length for crypt_unix is 8 characters.
USAGE
The return value of the crypt_unix algorithm might not be portable among standard-conforming systems. See standards(5).
