The certificates -available via B<CAfile> and B<CApath> are trusted. - -=head1 NOTES - -If B<CAfile> is not NULL, it points to a file of CA certificates in PEM -format. The file can contain several CA certificates identified by - - -----BEGIN CERTIFICATE----- - ... (CA certificate in base64 encoding) ... - -----END CERTIFICATE----- - -sequences. Before, between, and after the certificates text is allowed -which can be used e.g. for descriptions of the certificates. - -The B<CAfile> is processed on execution of the SSL_CTX_load_verify_locations() -function. - -If B<CApath> is not NULL, it points to a directory containing CA certificates -in PEM format. The files each contain one CA certificate. The files are -looked up by the CA subject name hash value, which must hence be available. -If more than one CA certificate with the same name hash value exist, the -extension must be different (e.g. 9d66eef0.0, 9d66eef0.1 etc). The search -is performed in the ordering of the extension number, regardless of other -properties of the certificates. -Use the B<c_rehash> utility to create the necessary links. - -The certificates in B<CApath> are only looked up when required, e.g. when -building the certificate chain or when actually performing the verification -of a peer certificate. - -When looking up CA certificates, the OpenSSL library will first search the -certificates in B<CAfile>, then those in B<CApath>. Certificate matching -is done based on the subject name, the key identifier (if present), and the -serial number as taken from the certificate to be verified. If these data -do not match, the next certificate will be tried. If a first certificate -matching the parameters is found, the verification process will be performed; -no other certificates for the same parameters will be searched in case of -failure. - -In server mode, when requesting a client certificate, the server must send -the list of CAs of which it will accept client certificates. This list -is not influenced by the contents of B<CAfile> or B<CApath> and must -explicitly be set using the -L<SSL_CTX_set_client_CA_list(3)|SSL_CTX_set_client_CA_list(3)> -family of functions. - -When building its own certificate chain, an OpenSSL client/server will -try to fill in missing certificates from B<CAfile>/B<CApath>, if the -certificate chain was not explicitly specified (see -L<SSL_CTX_add_extra_chain_cert(3)|SSL_CTX_add_extra_chain_cert(3)>, -L<SSL_CTX_use_certificate(3)|SSL_CTX_use_certificate(3)>. - -=head1 WARNINGS - -If several CA certificates matching the name, key identifier, and serial -number condition are available, only the first one will be examined. This -may lead to unexpected results if the same CA certificate is available -with different expiration dates. If a "certificate expired" verification -error occurs, no other certificate will be searched. Make sure to not -have expired certificates mixed with valid ones. - -=head1 EXAMPLES - -Generate a CA certificate file with descriptive text from the CA certificates -ca1.pem ca2.pem ca3.pem: - - #!/bin/sh - rm CAfile.pem - for i in ca1.pem ca2.pem ca3.pem ; do - openssl x509 -in $i -text >> CAfile.pem - done - -Prepare the directory /some/where/certs containing several CA certificates -for use as B<CApath>: - - cd /some/where/certs - c_rehash . - -=head1 RETURN VALUES - -The following return values can occur: - -=over 4 - -=item 0 - -The operation failed because B<CAfile> and B<CApath> are NULL or the -processing at one of the locations specified failed. Check the error -stack to find out the reason. - -=item 1 - -The operation succeeded. - -=back - -=head1 SEE ALSO - -L<ssl(3)|ssl(3)>, -L<SSL_CTX_set_client_CA_list(3)|SSL_CTX_set_client_CA_list(3)>, -L<SSL_get_client_CA_list(3)|SSL_get_client_CA_list(3)>, -L<SSL_CTX_use_certificate(3)|SSL_CTX_use_certificate(3)>, -L<SSL_CTX_add_extra_chain_cert(3)|SSL_CTX_add_extra_chain_cert(3)>, -L<SSL_CTX_set_cert_store(3)|SSL_CTX_set_cert_store(3)> - -=cut |
