=head1 NAME

d2i_X509_ALGOR, i2d_X509_ALGOR - AlgorithmIdentifier functions.

=head1 SYNOPSIS

 #include <openssl/x509.h>

 X509_ALGOR *d2i_X509_ALGOR(X509_ALGOR **a, unsigned char **pp, long length);
 int i2d_X509_ALGOR(X509_ALGOR *a, unsigned char **pp);

=head1 DESCRIPTION

These functions decode and encode an B<X509_ALGOR> structure which is
equivalent to the B<AlgorithmIdentifier> structure.

Othewise these behave in a similar way to d2i_X509() and i2d_X509()
described in the L<d2i_X509(3)|d2i_X509(3)> manual page.
