This module maintains a concept of a current selection of entropy
|
|
source. Algorithms that require entropy 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.
