crypt_genhash_impl(3C) Standard C Library Functions crypt_genhash_impl(3C)NAMEcrypt_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 informa‐
tion 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.
