Description :
This module maintains a concept of a current selection of entropy source.
Algorithms that require entropy, such as those in
Data::Entropy::Algorithms, can use the source nominated by this module,
avoiding the need for entropy source objects to be explicitly passed
around. This is convenient because usually one entropy source will be used
for an entire program run and so an explicit entropy source parameter would
rarely vary. There is also a default entropy source, avoiding the need to
explicitly configure a source at all.
If nothing is done to set a source then it defaults to the use of Rijndael
(AES) in counter mode (see Data::Entropy::RawSource::CryptCounter and
Crypt::Rijndael), keyed using Perl\'s built-in \'rand\' function. This gives a
data stream that looks like concentrated entropy, but really only has at
most the entropy of the \'rand\' seed. Within a single run it is
cryptographically difficult to detect the correlation between parts of the
pseudo-entropy stream. If more true entropy is required then it is
necessary to configure a different entropy source.
