NAME
d2i_X509_ALGOR, i2d_X509_ALGOR, d2i_X509_ALGORS, i2d_X509_ALGORS - decode
and encode algorithm identifiers
SYNOPSIS
#include <openssl/x509.h>
X509_ALGOR *
d2i_X509_ALGOR(X509_ALGOR **val_out, const unsigned char **der_in,
long length);
int
i2d_X509_ALGOR(X509_ALGOR *val_in, unsigned char **der_out);
X509_ALGORS *
d2i_X509_ALGORS(X509_ALGORS **val_out, const unsigned char **der_in,
long length);
int
i2d_X509_ALGORS(X509_ALGORS *val_in, unsigned char **der_out);
DESCRIPTION
d2i_X509_ALGOR() and i2d_X509_ALGOR() decode and encode an ASN.1
AlgorithmIdentifier structure defined in RFC 5280 section 4.1.1.2.
d2i_X509_ALGORS() and i2d_X509_ALGORS() decode and encode an ASN.1
sequence of AlgorithmIdentifier structures. The data type X509_ALGORS is
defined as STACK_OF(X509_ALGOR).
For details about the semantics, examples, caveats, and bugs, see
ASN1_item_d2i(3).
