=head1 SYNOPSIS
|
|
|
|
#include "internal/der.h"
|
|
|
|
int ossl_DER_w_boolean(WPACKET *pkt, int tag, int b);
|
|
int ossl_DER_w_uint32(WPACKET *pkt, int tag, uint32_t v);
|
|
int ossl_DER_w_bn(WPACKET *pkt, int tag, const BIGNUM *v);
|
|
int ossl_DER_w_null(WPACKET *pkt, int tag);
|
|
int ossl_DER_w_octet_string(WPACKET *pkt, int tag,
|
|
const unsigned char *data, size_t data_n);
|
|
int ossl_DER_w_octet_string_uint32(WPACKET *pkt, int tag, uint32_t value);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
All functions described here behave the same way, they prepend
|
|
(remember that DER writers are used backwards) the DER encoding of
|
|
their respective value to the already written output buffer held by
|
|
I<pkt>.
|
|
|
|
ossl_DER_w_boolean() writes the primitive BOOLEAN using the value I<b>.
|
|
Any value that evaluates as true will render a B<true> BOOLEAN,
|
|
otherwise a B<false> BOOLEAN.
|
|
|
|
ossl_DER_w_uint32() and ossl_DER_w_bn() both write the primitive INTEGER using
|
|
the value I<v>.
|
|
|
|
=for comment Other similar functions for diverse C integers should be
|
|
added.
|
|
|
|
ossl_DER_w_null() writes the primitive NULL.
|
|
|
|
ossl_DER_w_octet_string() writes the primitive OCTET STRING using the bytes
|
|
from I<data> with a length of I<data_n>.
|
|
|
|
ossl_DER_w_octet_string_uint32() writes the primitive OCTET STRING using a
|
|
32 bit value in I<value>.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
All the functions return 1 on success and 0 on failure. Failure may
|
|
mean that the buffer held by the I<pkt> is too small, but may also
|
|
mean that the values given to the functions are invalid, such as the provided
|
|
I<tag> value being too large for the implementation.
