NAME

Crypt::OpenSSL::RSA - RSA encoding and decoding, using the openSSL libraries

Crypt::OpenSSL::Random - Routines for accessing the OpenSSL pseudo-random number generator

SYNOPSIS

use Crypt::OpenSSL::Random;

DESCRIPTION

Crypt::OpenSSL::Random provides the ability to seed and query the OpenSSL library's pseudo-random number generator

EXPORT

None by default.

Static Methods

random_bytes

This function, returns a specified number of cryptographically strong pseudo-random bytes from the PRNG. If the PRNG has not been seeded with enough randomness to ensure an unpredictable byte sequence, then a false value is returned.

random_pseudo_bytes

This function, is similar to c<random_bytes>, but the resulting sequence of bytes are not necessarily unpredictable. They can be used for non-cryptographic purposes and for certain purposes in cryptographic protocols, but usually not for key generation etc.

random_seed

This function seeds the PRNG with a supplied string of bytes. It returns true if the PRNG has sufficient seeding. Note: calling this function with non-random bytes is of limited value at best!

random_egd

This function seeds the PRNG with data from the specified entropy gathering daemon. Returns the number of bytes read from the daemon on succes, or -1 if not enough bytes were read, or if the connection to the daemon failed.

random_status

This function returns true if the PRNG has sufficient seeding.
