Crypt::Random::Source::Weak::openssl - Get random bytes from the OpenSSL command line utility
use Crypt::Random::Source::Strong::openssl;
my $source = Crypt::Random::Source::Weak::openssl->new
my $bytes = $source->get(1024); # get 1kb of random bytes
This is a weak random byte source because openssl rand is a PRNG.
This is a subclass of Crypt::Random::Source::Base::Proc.
Due to the retarded nature of the rand command line utility's interface, it must repeatedly be invoked with default_chunk_size as number of random bytes to generate.
The default number of bytes to generate per openssl rand invocation.
Defaults to 64 kb, which is pretty large and balances well with the startup time of openssl rand for miniscule chunks.
If you will be needing a lot of random data, increasing this number to something much larger would probably be beneficial.
The openssl executable to invoke. Defaults to what File::Which found for openssl (which means it must be in your PATH).
