Method: OpenSSL::PKey::DH.generate

Defined in:
ossl_pkey_dh.c

.generate(size[, generator]) ⇒ Object

Creates a new DH instance from scratch by generating the private and public components alike.

Parameters

  • 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.
