Hashing or MD5

Hi, how can one find that which encryption algorithm the system is using for keeping the user password in the /etc/passwd or /etc/shadow file. Is it 1: Hashing ( which considers only first 5 letters of password) 2: MD5 (Which allows arbitry length passwords) Thanks, ~amit

encrypt

encrypt(3C)						   Standard C Library Functions 					       encrypt(3C)

NAME

       encrypt - encoding function

SYNOPSIS

       #include <crypt.h>

       void encrypt(char block[64], int edflag);

   Standard conforming
       #include <unistd.h>

       void encrypt(char block[64], int edflag);

DESCRIPTION

       The encrypt() function provides (rather primitive) access to the hashing algorithm employed by the crypt(3C) function. The key generated by
       setkey(3C) is used to encrypt the string block with encrypt().

       The block argument to encrypt() is an array of length 64 bytes containing only the bytes with numerical value of 0 and 1. The array is mod-
       ified  in  place to a similar array using the key set by setkey(3C). If edflag is 0, the argument is encoded.  If edflag is 1, the argument
       may be decoded (see the USAGE section below); if the argument is not decoded, errno will be set to ENOSYS.

RETURN VALUES

       The encrypt() function returns no value.

ERRORS

       The encrypt() function will fail if:

       ENOSYS	       The functionality is not supported on this implementation.

USAGE

       In some environments, decoding may not be implemented.  This is related to U.S. Government restrictions on encryption and  decryption  rou-
       tines:  the  DES decryption algorithm cannot be exported outside the U.S.A. Historical practice has been to ship a different version of the
       encryption library without the decryption feature in the routines supplied. Thus the exported version of encrypt() does	encoding  but  not
       decoding.

       Because	encrypt() does not return a value, applications wishing to check for errors should set errno to 0, call encrypt(), then test errno
       and, if it is non-zero, assume an error has occurred.
