def algorithm
  case __getobj__
  when OpenSSL::PKey::RSA then :rsa
  when OpenSSL::PKey::DSA then :dsa
  when OpenSSL::PKey::DH  then :dh
  when OpenSSL::PKey::EC  then :ec
  end
end

#size ⇒ Integer

The size of the public key.

Returns:

  • (Integer) —

    The number of bits in the public key.

Raises:

  • (NotImplementedError) —

    Determining key size for OpenSSL::PKey::EC public keys is currently not implemented.

Since:

  • 1.0.0
