If B<idx> is B<NULL> then only one occurrence of an extension is permissible otherwise the first extension after index B<*idx> is returned and B<*idx> updated to the location of the extension. If B<crit> is not B<NULL> then B<*crit> is set to a status value: -2 if the extension occurs multiple times (this is only returned if B<idx> is B<NULL>), -1 if the extension could not be found, 0 if the extension is found and is not critical and 1 if critical. A pointer to an extension specific structure or B<NULL> is returned. X509V3_add1_i2d() adds extension B<value> to STACK B<*x> (allocating a new STACK if necessary) using OID B<nid> and criticality B<crit> according to B<flags>. X509V3_EXT_d2i() attempts to decode the ASN.1 data contained in extension B<ext> and returns a pointer to an extension specific structure or B<NULL> if the extension could not be decoded (invalid syntax or not supported). X509V3_EXT_i2d() encodes the extension specific structure B<ext> with OID B<ext_nid> and criticality B<crit>. X509_get_ext_d2i() and X509_add1_ext_i2d() operate on the extensions of certificate B<x>, they are otherwise identical to X509V3_get_d2i() and X509V3_add_i2d(). X509_CRL_get_ext_d2i() and X509_CRL_add1_ext_i2d() operate on the extensions of CRL B<crl>, they are otherwise identical to X509V3_get_d2i() and X509V3_add_i2d(). X509_REVOKED_get_ext_d2i() and X509_REVOKED_add1_ext_i2d() operate on the extensions of B<X509_REVOKED> structure B<r> (i.e for CRL entry extensions), they are otherwise identical to X509V3_get_d2i() and X509V3_add_i2d(). X509_get0_extensions(), X509_CRL_get0_extensions() and X509_REVOKED_get0_extensions() return a stack of all the extensions of a certificate a CRL or a CRL entry respectively. =head1 NOTES In almost all cases an extension can occur at most once and multiple occurrences is an error. Therefore, the B<idx> parameter is usually B<NULL>. The B<flags> parameter may be one of the following values. B<X509V3_ADD_DEFAULT> appends a new extension only if the extension does not already exist. An error is returned if the extension does already exist. B<X509V3_ADD_APPEND> appends a new extension, ignoring whether the extension already exists. B<X509V3_ADD_REPLACE> replaces an extension if it exists otherwise appends a new extension. B<X509V3_ADD_REPLACE_EXISTING> replaces an existing extension if it exists otherwise returns an error. B<X509V3_ADD_KEEP_EXISTING> appends a new extension only if the extension does not already exist. An error B<is not> returned if the extension does already exist. B<X509V3_ADD_DELETE> extension B<nid> is deleted: no new extension is added. If B<X509V3_ADD_SILENT> is ored with B<flags>: any error returned will not be added to the error queue. The function X509V3_get_d2i() will return B<NULL> if the extension is not found, occurs multiple times or cannot be decoded. It is possible to determine the precise reason by checking the value of B<*crit>. =head1 SUPPORTED EXTENSIONS The following sections contain a list of all supported extensions including their name and NID. =head2 PKIX Certificate Extensions The following certificate extensions are defined in PKIX standards such as RFC5280.

CRL Number NID_crl_number CRL Distribution Points NID_crl_distribution_points Delta CRL Indicator NID_delta_crl Freshest CRL NID_freshest_crl Invalidity Date NID_invalidity_date Issuing Distribution Point NID_issuing_distribution_point The following are CRL entry extensions from PKIX standards such as RFC5280.

X509V3_EXT_i2d() returns a pointer to an B<X509_EXTENSION> structure or B<NULL> if an error occurs. X509V3_add1_i2d() returns 1 if the operation is successful and 0 if it fails due to a non-fatal error (extension not found, already exists, cannot be encoded) or -1 due to a fatal error such as a memory allocation failure. X509_get0_extensions(), X509_CRL_get0_extensions() and X509_REVOKED_get0_extensions() return a stack of extensions. They return NULL if no extensions are present. =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_pubkey(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<X509_verify_cert(3)> =head1 COPYRIGHT Copyright 2015-2020 The OpenSSL Project Authors.
