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

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.

Foo::Bar &&= baz ^^^^^^^^^^^^^^^^

Foo::Bar ||= baz ^^^^^^^^^^^^^^^^

@foo += bar ^^^^^^^^^^^

if /foo #{bar}/ then end

^^^^^^^^^^^^

Generates a valid JSON document from object obj and returns the result. If no valid JSON document can be created this method raises a GeneratorError exception.

Returns the generator of the group.

See the OpenSSL documentation for EC_GROUP_get0_generator()

Foo += bar ^^^^^^^^^^^

Foo::Bar = 1 ^^^^^^^^^^^^

Foo::Foo, Bar::Bar = 1 ^^^^^^^^ ^^^^^^^^

@foo, = bar ^^^^

Foo += bar ^^^^^^^^^^^

Foo::Bar = 1 ^^^^^^^^^^^^

Foo::Foo, Bar::Bar = 1 ^^^^^^^^ ^^^^^^^^

@foo, = bar ^^^^

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.

Deprecated in version 3.0. This method is incompatible with OpenSSL 3.0.0 or later.

See also OpenSSL::PKey.generate_key.

Example:

# DEPRECATED USAGE: This will not work on OpenSSL 3.0 or later
dh0 = OpenSSL::PKey::DH.new(2048)
dh = dh0.public_key # #public_key only copies the DH parameters (contrary to the name)
dh.generate_key!
puts dh.private? # => true
puts dh0.pub_key == dh.pub_key #=> false

# With OpenSSL::PKey.generate_key
dh0 = OpenSSL::PKey::DH.new(2048)
dh = OpenSSL::PKey.generate_key(dh0)
puts dh0.pub_key == dh.pub_key #=> false

See the OpenSSL documentation for EC_KEY_get0_private_key()

See the OpenSSL documentation for EC_KEY_set_private_key()

Generates a new random private and public key.

See also the OpenSSL documentation for EC_KEY_generate_key()

Example

ec = OpenSSL::PKey::EC.new("prime256v1")
p ec.private_key # => nil
ec.generate_key!
p ec.private_key # => #<OpenSSL::BN XXXXXX>

Returns whether this EC instance has a private key. The private key (BN) can be retrieved with EC#private_key.

Generates a new random private and public key.

See also the OpenSSL documentation for EC_KEY_generate_key()

Example

ec = OpenSSL::PKey::EC.new("prime256v1")
p ec.private_key # => nil
ec.generate_key!
p ec.private_key # => #<OpenSSL::BN XXXXXX>

Encrypt string with the private key. padding defaults to PKCS1_PADDING, which is known to be insecure but is kept for backwards compatibility. The encrypted string output can be decrypted using public_decrypt.

Deprecated in version 3.0. Consider using PKey::PKey#sign_raw and PKey::PKey#verify_raw, and PKey::PKey#verify_recover instead.

Decrypt string, which has been encrypted with the public key, with the private key. padding defaults to PKCS1_PADDING, which is known to be insecure but is kept for backwards compatibility.

Deprecated in version 3.0. Consider using PKey::PKey#encrypt and PKey::PKey#decrypt instead.
