Constructor Detail
Instance Method Detail
Adds options to the TLS context.
Example:
context.add_options(
OpenSSL::SSL::Options::ALL | # various workarounds
OpenSSL::SSL::Options::NO_SSL_V2 | # disable overly deprecated SSLv2
OpenSSL::SSL::Options::NO_SSL_V3 # disable deprecated SSLv3
)
Sets the path to a file containing all CA certificates, in PEM format, used to validate the peers certificate.
Sets the path to a directory containing all CA certificates used to
validate the peers certificate. The certificates should be in PEM format
and the c_rehash(1)
utility must have been run in the directory.
Specify the path to the certificate chain file to use. In server mode this is presented to the client, in client mode this used as client certificate.
Specify the path to the private key to use. The key must in PEM format.
The key must correspond to the entity certificate set by #certificate_chain=
.
Removes options from the TLS context.
Example:
context.remove_options(OpenSSL::SSL::Options::NO_SSL_V3)
Sets the default paths for ca_certiifcates=
and #ca_certificates_path=
.
Adds a temporary ECDH key curve to the TLS context. This is required to enable the EECDH cipher suites. By default the prime256 curve will be used.
Returns the current verify mode. See the SSL_CTX_set_verify(3)
manpage for more details.
Sets the verify mode. See the SSL_CTX_set_verify(3)
manpage for more details.
