NAME
Math::Prime::Util::RandomPrimes - Generate random primes
VERSION
Version 0.41
SYNOPSIS
DESCRIPTION
Routines to generate random primes, including constructing proven primes.
RANDOM UTILITY FUNCTIONS
get_randf
Gets a subroutine that will produce random integers between 0 and n
, inclusive. The argument n
can be a bigint.
get_randf_nbit
Gets a subroutine that will produce random integers between 0 and 2^n-1
, inclusive.
RANDOM PRIME FUNCTIONS
random_prime
Generate a random prime between low
and high
. If given one argument, low
will be 2.
random_ndigit_prime
Generate a random prime with n
digits. n
must be at least 1.
random_nbit_prime
Generate a random prime with n
bits. n
must be at least 2.
random_maurer_prime
Construct a random provable prime of n
bits using Maurer's FastPrime algorithm. n
must be at least 2.
random_maurer_prime_with_cert
Construct a random provable prime of n
bits using Maurer's FastPrime algorithm. n
must be at least 2. Returns a list of two items: the prime and the certificate.
random_shawe_taylor_prime
Construct a random provable prime of n
bits using Shawe-Taylor's algorithm. n
must be at least 2. The implementation is from FIPS 186-4 and uses SHA-256 with 512 bits of randomness.
random_shawe_taylor_prime_with_cert
Construct a random provable prime of n
bits using Shawe-Taylor's algorithm. n
must be at least 2. Returns a list of two items: the prime and the certificate.
random_strong_prime
Construct a random strong prime of n
bits. n
must be at least 128.
random_proven_prime
Generate or construct a random provable prime of n
bits. n
must be at least 2.
random_proven_prime_with_cert
Generate or construct a random provable prime of n
bits. n
must be at least 2. Returns a list of two items: the prime and the certificate.
RANDOM PRIMALITY FUNCTIONS
miller_rabin_random
Given a number n
and a number of tests to perform k
, this does k
Miller-Rabin tests on n
using randomly selected bases. The return value is 1 if all bases are a witness to to n
, or 0 if any of them fail.
