xdecrypt(3) [linux man page]

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. SEE ALSO
cbc_crypt(3) COLOPHON
