| |
| OSSL_CMP_MSG_get0_header, |
| d2i_OSSL_CMP_MSG_bio, |
| i2d_OSSL_CMP_MSG_bio |
| - function(s) manipulating CMP messages |
| |
| =head1 SYNOPSIS |
| |
| #include <openssl/cmp.h> |
| |
| OSSL_CMP_PKIHEADER *OSSL_CMP_MSG_get0_header(const OSSL_CMP_MSG *msg); |
| OSSL_CMP_MSG *d2i_OSSL_CMP_MSG_bio(BIO *bio, OSSL_CMP_MSG **msg); |
| int i2d_OSSL_CMP_MSG_bio(BIO *bio, const OSSL_CMP_MSG *msg); |
| |
| =head1 DESCRIPTION |
| |
| OSSL_CMP_MSG_get0_header returns the header of the given CMP message. |
| |
| d2i_OSSL_CMP_MSG_bio parses an ASN.1-encoded OSSL_CMP_MSG from the BIO I<bio>. |
| It assigns a pointer to the new structure to I<*msg> if I<msg> is not NULL. |
| |
| i2d_OSSL_CMP_MSG_bio writes the OSSL_CMP_MSG I<msg> in ASN.1 encoding |
| to BIO I<bio>. |
| |
| =head1 NOTES |
| |
| CMP is defined in RFC 4210. |
| |
| =head1 RETURN VALUES |
| |
| OSSL_CMP_MSG_get0_header() returns the intended pointer value as described above |
| or NULL if the respective entry does not exist and on error. |
| |
| d2i_OSSL_CMP_MSG_bio() returns the parsed message or NULL on error. |
| |
| i2d_OSSL_CMP_MSG_bio() returns 1 on success or 0 on error. |
| |
| =head1 HISTORY |
| |
| The OpenSSL CMP support was added in OpenSSL 3.0. |
