NAME
OBJ_add_sigid, OBJ_sigid_free,
OBJ_find_sigid_algs,
OBJ_find_sigid_by_algs —
SYNOPSIS
#include <openssl/objects.h>
int
OBJ_add_sigid(int signature,
int digest, int encryption);
void
OBJ_sigid_free(void);
int
OBJ_find_sigid_algs(int
signature, int *pdigest, int
*pencryption);
int
OBJ_find_sigid_by_algs(int
*psignature, int digest, int
encryption);
DESCRIPTION
OBJ_add_sigid() defines the
signature algorithm to use the specified
digest and encryption algorithms.
Making sure that this does not conflict with earlier invocations of
OBJ_add_sigid() is the responsibility of the caller.
Definitions made with OBJ_add_sigid() take precedence
over definitions built into the library.
OBJ_sigid_free() deletes all definitions
made with OBJ_add_sigid().
OBJ_find_sigid_algs() looks up the
signature algorithm. If it is found, the associated
digest algorithm is stored in *pdigest unless
pdigest is a NULL pointer, and
the associated encryption algorithm is stored in
*pencryption unless pencryption
is a NULL pointer.
OBJ_find_sigid_by_algs() looks up the pair
(digest, encryption). If it is
found, the associated signature algorithm is stored in
*psignature unless psignature is
a NULL pointer.
RETURN VALUES
OBJ_add_sigid() returns 1 on success or 0 if memory
allocation fails.
OBJ_find_sigid_algs() returns 1 if a
definition of the signature algorithm is found or 0 if
a definition of the signature algorithm is neither
built into the library nor provided with
OBJ_add_sigid().
OBJ_find_sigid_by_algs() returns 1 if a
signature algorithm using the specified digest and
encryption algorithms is defined or 0 if the
definition of such an algorithm is neither built into the library nor
provided with OBJ_add_sigid().
