crypt_gensalt_impl(3c)

Standard C Library Functions                            crypt_gensalt_impl(3C)



NAME
       crypt_gensalt_impl - generate salt for password encryption

SYNOPSIS
       #include <crypt.h>

       char *crypt_gensalt_impl(char *gsbuffer, size_t gsbufflen,
            const char *oldsalt, const struct passwd *userinfo,
            const char **params);

DESCRIPTION
       The  crypt_gensalt_impl() function provided by a pluggable crypt module
       is called by is called by crypt_gensalt(3C) to generate  the  salt  for
       password encryption.


       The  gsbuffer argument is a pointer to an MT-safe buffer of size gsbuf‐
       flen.


       The oldsalt and userinfo arguments are passed unchanged from crypt_gen‐
       salt(3C).


       The params argument is an argv-like null terminated vector of type char
       *. The first element of params represents the mechanism token name from
       crypt.conf(5).  The  remaining  elements of params represent strings of
       the form <parameter>[=<value>] to allow passing in additional  informa‐
       tion  from  the crypt.conf entry, such as specifying rounds information
       "rounds=4096".


       The value returned by crypt_gensalt_impl() points to a  thread-specific
       buffer  to  be  freed  by the caller of crypt_gensalt(3C) after calling
       crypt(3C).

RETURN VALUES
       Upon successful completion, crypt_gensalt_impl() returns a  pointer  to
       the  new salt. Otherwise a null pointer is returned and errno is set to
       indicate the error.

ERRORS
       The crypt_gensalt_impl() function will fail if:

       EINVAL     The configuration file crypt.conf contains an invalid entry.


       ELIBACC    The required crypt shared library was not found.


       ENOMEM     There is insufficient memory to perform hashing.
