NAME
       crypt_genhash_impl - generate encrypted password

SYNOPSIS
       #include <crypt.h>

       char *crypt_genhash_impl(char *ctbuffer, size_t ctbufflen, const char *plaintext, const char *salt, const char **params);

DESCRIPTION
       The crypt_genhash_impl() function is called by crypt(3C) to generate the encrypted password plaintext.

       The ctbuffer argument is a pointer to an MT-safe buffer of ctbufflen size that is used to return the result.

       The salt argument is the salt used in encoding.

       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(4). The remaining elements of params represent strings of the form <parameter>[=<value>] to  allow  passing  in	additional
       information from the crypt.conf entry, such as specifing rounds information "rounds=4096".

       The crypt_genhash_impl() function must not free(3C) ctbufflen on error.

RETURN VALUES
       Upon  successful  completion,  crypt_genhash_impl()  returns  a	pointer  to  the encoded version of plaintext. Otherwise a null pointer is
       returned and errno is set to indicate the error.

ERRORS
       The crypt_genhash_impl() function will fail if:

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

       ELIBACC	       The required shared library was not found.

       ENOMEM	       There is insufficient memory to perform hashing.
