-=head1 NAME
-
-SSL_CTX_load_verify_locations - set default locations for trusted CA
-certificates
-
-=head1 SYNOPSIS
-
- #include <openssl/ssl.h>
-
- int SSL_CTX_load_verify_locations(SSL_CTX *ctx, const char *CAfile,
- const char *CApath);
-
-=head1 DESCRIPTION
-
-SSL_CTX_load_verify_locations() specifies the locations for B<ctx>, at
-which CA certificates for verification purposes are located. 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.
