Class Method Details

.generate_key_pair(private_file = "rsa_key", public_file = "#{private_file}.pub", bits = 512, clean = true) ⇒ Object

Generate private and public keys

  1. private_file - file name of private key to generate (default = “rsa_key”)

  2. public_file - file name of public key to generate (default = “#private_key.pub”)

  3. bits - number of bits for key (default = 1024)

  4. clean - specifies if existing key files should zapped and replaced by newly generated keys (default = true)

Returns the private key generated.

Usage:

priv_key = Metafusion::Crypto.generate_key_pair
