The value 41returned is an internal pointer which must not be freed up after 42the call. I<x> B<MUST NOT> be NULL. 43 44X509_getm_notBefore() and X509_getm_notAfter() are similar to 45X509_get0_notBefore() and X509_get0_notAfter() except they return 46non-constant mutable references to the associated date field of 47the certificate. 48 49X509_set1_notBefore() and X509_set1_notAfter() set the B<notBefore> 50and B<notAfter> fields of I<x> to I<tm>. Ownership of the passed 51parameter I<tm> is not transferred by these functions so it must 52be freed up after the call. 53 54X509_ACERT_get0_notBefore() and X509_ACERT_get0_notAfter() return 55the B<notBefore> and B<notAfter> fields of certificate B<x> respectively. 56returned is an internal pointer which must not be freed up after 57the call. 58 59X509_ACERT_set1_notBefore() and X509_ACERT_set1_notAfter() set the B<notBefore> 60and B<notAfter> fields of B<x> to B<tm>. Ownership of the passed 61parameter B<tm> is not transferred by these functions so it must 62be freed up after the call. 63 64X509_CRL_get0_lastUpdate() and X509_CRL_get0_nextUpdate() return the 65B<lastUpdate> and B<nextUpdate> fields of I<crl>. The value 66returned is an internal pointer which must not be freed up after 67the call. If the B<nextUpdate> field is absent from I<crl> then 68NULL is returned. 69 70X509_CRL_set1_lastUpdate() and X509_CRL_set1_nextUpdate() set the B<lastUpdate> 71and B<nextUpdate> fields of I<crl> to I<tm>. Ownership of the passed parameter 72I<tm> is not transferred by these functions so it must be freed up after the 73call. 74For X509_CRL_set1_nextUpdate() the I<tm> argument may be NULL, 75which implies removal of the optional B<nextUpdate> field. 76 77=head1 RETURN VALUES 78 79X509_get0_notBefore(), X509_get0_notAfter() and X509_CRL_get0_lastUpdate() 80return a pointer to an B<ASN1_TIME> structure. 81 82X509_CRL_get0_lastUpdate() return a pointer to an B<ASN1_TIME> structure 83or NULL if the B<lastUpdate> field is absent. 84 85X509_set1_notBefore(), X509_set1_notAfter(), X509_CRL_set1_lastUpdate() and 86X509_CRL_set1_nextUpdate() return 1 for success or 0 for failure. 87 88=head1 NOTES 89 90Unlike the B<X509> and B<X509_CRL> routines, the B<X509_ACERT> routines 91use the ASN1_GENERALIZEDTIME format instead of ASN1_TIME for holding time 92data. 93 94=head1 SEE ALSO 95 96L<d2i_X509(3)>, 97L<ASN1_GENERALIZEDTIME_check(3)> 98L<ERR_get_error(3)>, 99L<X509_CRL_get0_by_serial(3)>, 100L<X509_get0_signature(3)>, 101L<X509_get_ext_d2i(3)>, 102L<X509_get_extension_flags(3)>, 103L<X509_get_pubkey(3)>, 104L<X509_get_subject_name(3)>, 105L<X509_NAME_add_entry_by_txt(3)>, 106L<X509_NAME_ENTRY_get_object(3)>, 107L<X509_NAME_get_index_by_NID(3)>, 108L<X509_NAME_print_ex(3)>, 109L<X509_new(3)>, 110L<X509_sign(3)>, 111L<X509V3_get_d2i(3)>, 112L<X509_verify_cert(3)> 113 114=head1 HISTORY 115 116These functions are available in all versions of OpenSSL. 117 118X509_get_notBefore() and X509_get_notAfter() were deprecated in OpenSSL 1191.1.0 120 121=head1 COPYRIGHT 122 123Copyright 2016-2024 The OpenSSL Project Authors.
