OpenSSL::SSL::Context::Client

Inherits OpenSSL::SSL::Context / Reference / Object

Constructors

from_hash(params) : self

Configures a client context from a hash-like interface.

require "openssl"

context = OpenSSL::SSL::Context::Client.from_hash({"key" => "private.key", "cert" => "certificate.crt", "ca" => "ca.pem"})

Params:

key (required): Path to private key file. See #private_key=.
cert (required): Path to the file containing the public certificate chain. See #certificate_chain=.
verify_mode: Either peer, force-peer, none or empty (default: peer). See verify_mode=.
ca: Path to a file containing the CA certificate chain or a directory containing all CA certificates. See #ca_certificates= and #ca_certificates_path=, respectively. Required if verify_mode is peer, force-peer or empty.

Source

insecure(method : LibSSL::SSLMethod = Context.default_method) : self

Returns a new TLS client context with only the given method set.

For everything else this uses the defaults of your OpenSSL. Use this only if undoing the defaults that new sets is too much hassle.

Source

new(method : LibSSL::SSLMethod = Context.default_method)

Generates a new TLS client context with sane defaults for a client connection.

Defaults to TLS_method or SSLv23_method (depending on OpenSSL version) which tells OpenSSL to negotiate the TLS or SSL protocol with the remote endpoint.

Don't change the method unless you must restrict a specific protocol to be used (eg: TLSv1.2) and nothing else. You should specify options to disable specific protocols, yet allow to negotiate from various other ones. For example the following snippet will enable the TLSv1, TLSv1.1 and TLSv1.2 protocols but disable the deprecated SSLv2 and SSLv3 protocols:

require "openssl"

context = OpenSSL::SSL::Context::Client.new
context.add_options(OpenSSL::SSL::Options::NO_SSL_V2 | OpenSSL::SSL::Options::NO_SSL_V3)
