Validates the Diffie-Hellman parameters associated with this instance. It checks whether a safe prime and a suitable generator are used. If this is not the case, false is returned.

See also the man page EVP_PKEY_param_check(3).

Obtains a list of all predefined curves by the OpenSSL. Curve names are returned as sn.

See the OpenSSL documentation for EC_get_builtin_curves().

Sets saner defaults optimized for the use with HTTP-like protocols.

If a Hash params is given, the parameters are overridden with it. The keys in params must be assignment methods on SSLContext.

If the verify_mode is not VERIFY_NONE and ca_file, ca_path and cert_store are not set then the system default certificate store is used.

Sets the lower bound on the supported SSL/TLS protocol version. The version may be specified by an integer constant named OpenSSL::SSL::*_VERSION, a Symbol, or nil which means “any version”.

Be careful that you don’t overwrite OpenSSL::SSL::OP_NO_{SSL,TLS}v* options by options= once you have called min_version= or max_version=.

Example

ctx = OpenSSL::SSL::SSLContext.new
ctx.min_version = OpenSSL::SSL::TLS1_1_VERSION
ctx.max_version = OpenSSL::SSL::TLS1_2_VERSION

sock = OpenSSL::SSL::SSLSocket.new(tcp_sock, ctx)
sock.connect # Initiates a connection using either TLS 1.1 or TLS 1.2

Sets the upper bound of the supported SSL/TLS protocol version. See min_version= for the possible values.

Sets the SSL/TLS protocol version for the context. This forces connections to use only the specified protocol version. This is deprecated and only provided for backwards compatibility. Use min_version= and max_version= instead.

History

As the name hints, this used to call the SSL_CTX_set_ssl_version() function which sets the SSL method used for connections created from the context. As of Ruby/OpenSSL 2.1, this accessor method is implemented to call min_version= and max_version= instead.

Adds session to the session cache.

Removes session from the session cache.

Removes sessions in the internal cache that have expired at time.

Initiates the SSL/TLS handshake as a client in non-blocking manner.

# emulates blocking connect
begin
  ssl.connect_nonblock
rescue IO::WaitReadable
  IO.select([s2])
  retry
rescue IO::WaitWritable
  IO.select(nil, [s2])
  retry
end

By specifying a keyword argument exception to false, you can indicate that connect_nonblock should not raise an IO::WaitReadable or IO::WaitWritable exception, but return the symbol :wait_readable or :wait_writable instead.

Writes string to the SSL connection in a non-blocking manner. Raises an SSLError if writing would block.

Returns a String representing the SSL/TLS version that was negotiated for the connection, for example “TLSv1.2”.

Returns true if a reused session was negotiated during the handshake.

Parses the UTF-8 string representation of a distinguished name, according to RFC 2253.

See also to_utf8 for the opposite operation.
