XCRYPT(3) Linux Programmer's Manual XCRYPT(3)NAME
xencrypt, xdecrypt, passwd2des - RFS password encryption
SYNOPSIS
#include <rpc/des_crypt.h>
void passwd2des(char *passwd, char *key);
int xencrypt(char *secret, char *passwd);
int xdecrypt(char *secret, char *passwd);
DESCRIPTION
The function passwd2des() takes a character string passwd of arbitrary length and fills a character array key of length 8. The array key
is suitable for use as DES key. It has odd parity set in bit 0 of each byte. Both other functions described here use this function to
turn their argument passwd into a DES key.
The xencrypt() function takes the ASCII character string secret given in hex, which must have a length that is a multiple of 16, encrypts
it using the DES key derived from passwd by passwd2des(), and outputs the result again in secret as a hex string of the same length.
The xdecrypt() function performs the converse operation.
RETURN VALUE
The functions xencrypt() and xdecrypt() return 1 on success and 0 on error.
VERSIONS
These routines are present in libc 4.6.27 and later, and in glibc 2.1 and later.
BUGS
The prototypes are missing from the abovementioned include file.

Hi all,
I am using RHEL 5.0
I need a user say test to have full access to two directories, say /tmp1 & /tmp2 only other than his home directory.
I do not want to change his login shell which is ksh or bash by default.
Moreover, he should not even have read access of other directories.

Hi all,
I'd like to use the encryption method used to generate the /etc/shadow passwords.
The goal is to write a script that get a plain-text password as argument and returns an encrycped one.
Can you help me, please? (10 Replies)
Hi,
Any body can please point me to source code for implementing AES encryption in CTR mode i.e RFC 3686 (AES-CTR).I did googling but no good results. (6 Replies)
