DH.new([size [, generator] | string]) â dh
Class Public methods
Either generates a DH instance from scratch or by
reading already existing DH parameters from
string. Note that when reading a DH
instance from data that was encoded from a DH
instance by using #to_pem or #to_der the result will
not contain a public/private key pair yet. This needs to
be generated using #generate_key! first.
Parameters
-
sizeis an integer representing the desired key size. Keys smaller than 1024 bits should be considered insecure. -
generatoris a small number > 1, typically 2 or 5. -
stringcontains the DER or PEM encoded key.
