If +successful it returns the public key as an B<EVP_PKEY> pointer with its +reference count incremented: this means the returned key must be freed up +after use. + +X509_get_X509_PUBKEY() returns an internal pointer to the B<X509_PUBKEY> +structure which encodes the certificate of B<x>. The returned value +must not be freed up after use. + +X509_set_pubkey() attempts to set the public key for certificate B<x> to +B<pkey>. The key B<pkey> should be freed up after use. + +X509_REQ_get_pubkey(), X509_REQ_set_pubkey() and X509_REQ_get_X509_PUBKEY() +are similar but operate on certificate request B<req>. + +=head1 NOTES + +The first time a public key is decoded the B<EVP_PKEY> structure is +cached in the certificate or certificate request itself. Subsequent calls +return the cached structure with its reference count incremented to +improve performance. + +=head1 RETURN VALUES + +X509_get_pubkey(), X509_get_X509_PUBKEY(), X509_REQ_get_pubkey() and +X509_REQ_get_X509_PUBKEY() return a public key or B<NULL> if an error +occurred. + +X509_set_pubkey() and X509_REQ_set_pubkey() rerturn 1 for success and 0 +for failure. + +=head1 SEE ALSO + +L<d2i_X509(3)>, +L<ERR_get_error(3)>, +L<X509_CRL_get0_by_serial(3)>, +L<X509_get0_signature(3)>, +L<X509_get_ext_d2i(3)>, +L<X509_get_extension_flags(3)>, +L<X509_get_subject_name(3)>, +L<X509_get_version(3)>, +L<X509_NAME_add_entry_by_txt(3)>, +L<X509_NAME_ENTRY_get_object(3)>, +L<X509_NAME_get_index_by_NID(3)>, +L<X509_NAME_print_ex(3)>, +L<X509_new(3)>, +L<X509_sign(3)>, +L<X509V3_get_d2i(3)>, +L<X509_verify_cert(3)> + +=head1 HISTORY + +=cut |
