=head1 DESCRIPTION
|
||
|
|
|
||
|
|
Provides an interface to the BLAKE2s_256 digest algorithm.
|
||
|
|
|
||
|
|
=head1 EXPORT
|
||
|
|
|
||
|
|
Nothing is exported by default.
|
||
|
|
|
||
|
|
You can export selected functions:
|
||
|
|
|
||
|
|
use Crypt::Digest::BLAKE2s_256 qw(blake2s_256 blake2s_256_hex blake2s_256_b64 blake2s_256_b64u
|
||
|
|
blake2s_256_file blake2s_256_file_hex blake2s_256_file_b64 blake2s_256_file_b64u);
|
||
|
|
|
||
|
|
Or all of them at once:
|
||
|
|
|
||
|
|
use Crypt::Digest::BLAKE2s_256 ':all';
