1=pod 2 3=head1 NAME 4 5ossl_DER_w_precompiled 6- internal DER writers for precompiled DER blobs 7 8=head1 SYNOPSIS 9 10 #include "internal/der.h" 11 12 int ossl_DER_w_precompiled(WPACKET *pkt, int tag, 13 const unsigned char *precompiled, 14 size_t precompiled_n); 15 16=head1 DESCRIPTION 17 18There may be already existing DER blobs that can simply be copied to 19the buffer held by I<pkt>. For example, precompiled values, such as 20OIDs (for example, C<id-sha256>) or complete AlgorithmIdentifiers 21(for example, C<sha256Identifier>). To add those as an element in a 22structure being DER encoded, use ossl_DER_w_precompiled(). 23 24ossl_DER_w_precompiled() will simply take the DER encoded blob given as 25I<precompiled> with length I<precompiled_n> and add it to the buffer 26held by I<pkt>. 27 28=head1 RETURN VALUES 29 30ossl_DER_w_precompiled() returns 1 on success and 0 on failure. Failure 31may mean that the buffer held by the I<pkt> is too small, but may also 32mean that the values given to the functions are invalid, such as the provided 33I<tag> value being too large for the implementation. 34 35=head1 SEE ALSO 36 37L<DERlib(7)> 38 39=head1 COPYRIGHT 40 41Copyright 2020 The OpenSSL Project Authors.
