=head1 SYNOPSIS
|
|
|
|
#include <openssl/x509.h>
|
|
|
|
X509_ALGOR *X509_ALGOR_dup(X509_ALGOR *alg);
|
|
int X509_ALGOR_set0(X509_ALGOR *alg, ASN1_OBJECT *aobj, int ptype, void *pval);
|
|
void X509_ALGOR_get0(const ASN1_OBJECT **paobj, int *pptype,
|
|
const void **ppval, const X509_ALGOR *alg);
|
|
void X509_ALGOR_set_md(X509_ALGOR *alg, const EVP_MD *md);
|
|
int X509_ALGOR_cmp(const X509_ALGOR *a, const X509_ALGOR *b);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
X509_ALGOR_dup() returns a copy of B<alg>.
|
|
|
|
X509_ALGOR_set0() sets the algorithm OID of B<alg> to B<aobj> and the
|
|
associated parameter type to B<ptype> with value B<pval>. If B<ptype> is
|
|
B<V_ASN1_UNDEF> the parameter is omitted, otherwise B<ptype> and B<pval> have
|
|
the same meaning as the B<type> and B<value> parameters to ASN1_TYPE_set().
|
|
All the supplied parameters are used internally so must B<NOT> be freed after
|
|
this call.
|
|
|
|
X509_ALGOR_get0() is the inverse of X509_ALGOR_set0(): it returns the
|
|
algorithm OID in B<*paobj> and the associated parameter in B<*pptype>
|
|
and B<*ppval> from the B<AlgorithmIdentifier> B<alg>.
|
|
|
|
X509_ALGOR_set_md() sets the B<AlgorithmIdentifier> B<alg> to appropriate
|
|
values for the message digest B<md>.
|
|
|
|
X509_ALGOR_cmp() compares B<a> and B<b> and returns 0 if they have identical
|
|
encodings and nonzero otherwise.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
X509_ALGOR_dup() returns a valid B<X509_ALGOR> structure or NULL if an error
|
|
occurred.
|
|
|
|
X509_ALGOR_set0() returns 1 on success or 0 on error.
|
|
|
|
X509_ALGOR_get0() and X509_ALGOR_set_md() return no values.
|
|
|
|
X509_ALGOR_cmp() returns 0 if the two parameters have identical encodings and
|
|
nonzero otherwise.
