new(p1 = v1, p2 = v2) public

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 DH#to_pem or DH#to_der the result will not contain a public/private key pair yet. This needs to be generated using DH#generate_key! first.


  • size is an integer representing the desired key size. Keys smaller than 1024 bits should be considered insecure.

  • generator is a small number > 1, typically 2 or 5.

  • string contains the DER or PEM encoded key.


DH.new # -> dh DH.new(1024) # -> dh DH.new(1024, 5) # -> dh #Reading DH parameters dh = DH.new(File.read(‘parameters.pem’)) # -> dh, but no public/private key yet dh.generate_key! # -> dh with public and private key
