securerandom

Base class for cryptographic secure random number generation :authors: Gary Belvin

class securerandom.OpenSSLRand

Bases: SecureRandom

Uses the OpenSSL PRNG for random bits

getRandomBits(length)

getRandomBytes(length)

Returns a random bit string of length bytes

class securerandom.SecureRandom

Bases: object

addSeed(seed)

Add randomness to the generator. Always increases entropy

getRandomBytes(length)

Returns a random bit string of length bytes

class securerandom.SecureRandomFactory

Bases: object

This class provides a central place to swap out the randomness engine used by the charm framework. Classes should call rand = SecureRandomFactory.getInstance() to acquire a randomnesss generator

classmethod getInstance()

class securerandom.WeakRandom

Bases: SecureRandom

addSeed(seed)

Add randomness to the generator. Always increases entropy

getRandomBytes(length)

Returns a random bit string of length bytes

classmethod myrandom(length, printable=False)

This method does NOT provide cryptographically secure random numbers. This should NOT be used for production code
