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.

AVAILABILITY

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.
