Returns the latest release-version specification for the gem name.

Returns the latest release version of RubyGems.

Returns the version of the latest release-version of gem name

Path to specification files of default gems.

Deduce Ruby’s –program-prefix and –program-suffix from its install name

The default signing key path

The default signing certificate chain path

Default options for gem commands for Ruby packagers.

The options here should be structured as an array of string “gem” command names as keys and a string of the default options as values.

Example:

def self.operating_system_defaults

{
    'install' => '--no-rdoc --no-ri --env-shebang',
    'update' => '--no-rdoc --no-ri --env-shebang'
}

end

Set the default id conversion object.

This is expected to be an instance such as DRb::DRbIdConv that responds to to_id and to_obj that can convert objects to and from DRb references.

See DRbServer#default_id_conv.

Shortcut for defining multiple delegator methods, but with no provision for using a different name. The following two code samples have the same effect:

def_delegators :@records, :size, :<<, :map

def_delegator :@records, :size
def_delegator :@records, :<<
def_delegator :@records, :map

Defines a method method which delegates to accessor (i.e. it calls the method of the same name in accessor). If new_name is provided, it is used as the name for the delegate method. Returns the name of the method defined.

Adds a certificate to the context. pkey must be a corresponding private key with certificate.

Multiple certificates with different public key type can be added by repeated calls of this method, and OpenSSL will choose the most appropriate certificate during the handshake.

cert=, key=, and extra_chain_cert= are old accessor methods for setting certificate and internally call this method.

Parameters

certificate

A certificate. An instance of OpenSSL::X509::Certificate.

pkey

The private key for certificate. An instance of OpenSSL::PKey::PKey.

extra_certs

Optional. An array of OpenSSL::X509::Certificate. When sending a certificate chain, the certificates specified by this are sent following certificate, in the order in the array.

Example

rsa_cert = OpenSSL::X509::Certificate.new(...)
rsa_pkey = OpenSSL::PKey.read(...)
ca_intermediate_cert = OpenSSL::X509::Certificate.new(...)
ctx.add_certificate(rsa_cert, rsa_pkey, [ca_intermediate_cert])

ecdsa_cert = ...
ecdsa_pkey = ...
another_ca_cert = ...
ctx.add_certificate(ecdsa_cert, ecdsa_pkey, [another_ca_cert])

Note

OpenSSL before the version 1.0.2 could handle only one extra chain across all key types. Calling this method discards the chain set previously.

Creates a new X509::Extension with passed values. See also x509v3_config(5).

Generates a private and public key unless a private key already exists. If this DH instance was generated from public DH parameters (e.g. by encoding the result of DH#public_key), then this method needs to be called first in order to generate the per-session keys before performing the actual key exchange.

Example

dh = OpenSSL::PKey::DH.new(2048)
public_key = dh.public_key #contains no private/public key yet
public_key.generate_key!
puts public_key.private? # => true
