|
|
SSL_CONF_CTX_set_flags, SSL_CONF_CTX_clear_flags - Set or clear SSL configuration context flags
|
|
=head1 SYNOPSIS
|
|
#include <openssl/ssl.h>
|
|
unsigned int SSL_CONF_CTX_set_flags(SSL_CONF_CTX *cctx, unsigned int flags);
|
unsigned int SSL_CONF_CTX_clear_flags(SSL_CONF_CTX *cctx, unsigned int flags);
|
|
=head1 DESCRIPTION
|
|
The function SSL_CONF_CTX_set_flags() sets B<flags> in the context B<cctx>.
|
|
The function SSL_CONF_CTX_clear_flags() clears B<flags> in the context B<cctx>.
|
|
=head1 NOTES
|
|
The flags set affect how subsequent calls to SSL_CONF_cmd() or
|
SSL_CONF_argv() behave.
|
|
Currently the following B<flags> values are recognised:
|
|
=over 4
|
|
=item SSL_CONF_FLAG_CMDLINE, SSL_CONF_FLAG_FILE
|
|
recognise options intended for command line or configuration file use. At
|
least one of these flags must be set.
|
|
=item SSL_CONF_FLAG_CLIENT, SSL_CONF_FLAG_SERVER
|
|
recognise options intended for use in SSL/TLS clients or servers. One or
|
both of these flags must be set.
|
|
=item SSL_CONF_FLAG_CERTIFICATE
|
|
recognise certificate and private key options.
|
|
=item SSL_CONF_FLAG_REQUIRE_PRIVATE
|
|
If this option is set then if a private key is not specified for a certificate
|
it will attempt to load a private key from the certificate file when
|
SSL_CONF_CTX_finish() is called. If a key cannot be loaded from the certificate
|
file an error occurs.
|
|
=item SSL_CONF_FLAG_SHOW_ERRORS
|
|
indicate errors relating to unrecognised options or missing arguments in
|
the error queue. If this option isn't set such errors are only reflected
|
in the return values of SSL_CONF_set_cmd() or SSL_CONF_set_argv()
|
|

|
|
=head1 RETURN VALUES
|
|
SSL_CONF_CTX_set_flags() and SSL_CONF_CTX_clear_flags() returns the new flags
|
value after setting or clearing flags.
