NAME
xencrypt, xdecrypt, passwd2des - RFS password encryptionSYNOPSIS
#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 functions are available in glibc since version 2.1.ATTRIBUTES
