Overview

Thrift cryptographics primitives: fast c++ implementation, only strong schemes, releases GVL on long operations so other threads can be executed in parallel.

Class Method Details

._factorize ⇒ Object

._generate_prime ⇒ Object

.factorize(composite) ⇒ int

Pollard ‘rho’ prime factorization. Allows execution of other ruby threads in parallel (releases GVL)

Returns:

  • (int) —

    array of prime factors

def factorize composite
  hex = composite.to_i.to_s(16)
  hex = '0' + hex if (hex.length & 1) == 1
  _factorize(hex).map { |x| x.to_i(16) }
end

.generate_prime(bits) ⇒ Object

Generate random probable prime number with a given bits length. This implementation will generate prime such as 2^(bits-1) < prime < 2 ^ bits.
