crypt_gensalt(3c)
Standard C Library Functions crypt_gensalt(3C)
NAME
crypt_gensalt - generate salt string for string encoding
SYNOPSIS
#include <crypt.h>
char *crypt_gensalt(const char *oldsalt, const struct passwd *userinfo);
DESCRIPTION
The crypt_gensalt() function generates the salt string required by
crypt(3C).
If oldsalt is NULL, crypt_gensalt() uses the algorithm defined by
CRYPT_DEFAULT in /etc/security/policy.conf. See policy.conf(5).
If oldsalt is non-null, crypt_gensalt() determines if the algorithm
specified by oldsalt is allowable by checking the CRYPT_ALGO‐
RITHMS_ALLOW and CRYPT_ALGORITHMS_DEPRECATE variables in /etc/secu‐
rity/policy.conf. If the algorithm is allowed, crypt_gensalt() loads
the appropriate shared library and calls crypt_gensalt_impl(3C). If the
algorithm is not allowed or there is no entry for it in crypt.conf,
crypt_gensalt() uses the default algorithm.
The mechanism just described provides a means to migrate users to new
password hashing algorithms when the password is changed.
RETURN VALUES
Upon successful completion, crypt_gensalt() 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() 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.
USAGE
The value returned by crypt_gensalt() points to a null-terminated
string. The caller of crypt_gensalt() is responsible for calling
free(3C).
Applications dealing with user authentication and password changing
should not call crypt_gensalt() directly but should instead call the
appropriate pam(3PAM) functions.
