Define method as delegator instance method with an optional alias name ali. Method calls to ali will be delegated to accessor.method. accessor should be a method name, instance variable name, or constant name. Use the full path to the constant if providing the constant name. Returns the name of the method defined.

class MyQueue
  CONST = 1
  extend Forwardable
  attr_reader :queue
  def initialize
    @queue = []
  end

  def_delegator :@queue, :push, :mypush
  def_delegator 'MyQueue::CONST', :to_i
end

q = MyQueue.new
q.mypush 42
q.queue    #=> [42]
q.push 23  #=> NoMethodError
q.to_i     #=> 1

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.

Should be implemented by a extended class.

tsort_each_node is used to iterate for all nodes over a graph.

Foo::Bar += baz ^^^^^^^^^^^^^^^

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()

Determine if characters preceeded by a backslash should be escaped or not

Returns the concatenated string from strings.

Read one byte from the tar entry

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>

Raises an exception if the key is invalid.

See also the man page EVP_PKEY_public_check(3).

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.
