PWSCHECK(3) BSD Library Functions Manual PWSCHECK(3)NAME
pws_passwords_check, pws_passwords_checkmulti — Functions to check a
given password against an encoded password
LIBRARY-lpwstor
SYNOPSIS
#include <pwstor.h>
int
pws_passwords_check(char *chk, const char *real, uint8_t is_b64);
int
pws_passwords_checkmulti(char *chk, PasswordData *real);
DESCRIPTION
The function pws_passwords_check() will check a given clear-text password
stored in chk against a string encoded by libpwstor which is stored in
real. If real is Base64 encoded, then is_b64 should be set to true. If
not, then is_b64 should be false. This function will return 0 to indi‐
cate a non-match, 1 to indicate that the passwords do indeed match, and
<0 to indicate a failure. In case of failure, errno can be examined to
assist in determining what failed. The EINVAL error indicates that one
of the arguments passed to pws_passwords_check() was not in a valid for‐
mat.
The function pws_passwords_checkmulti() returns the same codes as
pws_passwords_check() but expects the real argument to be a pointer to a
valid PasswordData structure.
