=head1 NAME
Crypt::Digest::BLAKE2b_512 - Hash function BLAKE2b [size: 512 bits]
=head1 SYNOPSIS
### Functional interface:
use Crypt::Digest::BLAKE2b_512 qw( blake2b_512 blake2b_512_hex blake2b_512_b64 blake2b_512_b64u
blake2b_512_file blake2b_512_file_hex blake2b_512_file_b64 blake2b_512_file_b64u );
# calculate digest from string/buffer
$blake2b_512_raw = blake2b_512('data string');
$blake2b_512_hex = blake2b_512_hex('data string');
$blake2b_512_b64 = blake2b_512_b64('data string');
$blake2b_512_b64u = blake2b_512_b64u('data string');
# calculate digest from file
$blake2b_512_raw = blake2b_512_file('filename.dat');
$blake2b_512_hex = blake2b_512_file_hex('filename.dat');
$blake2b_512_b64 = blake2b_512_file_b64('filename.dat');
$blake2b_512_b64u = blake2b_512_file_b64u('filename.dat');
# calculate digest from filehandle
$blake2b_512_raw = blake2b_512_file(*FILEHANDLE);
$blake2b_512_hex = blake2b_512_file_hex(*FILEHANDLE);
$blake2b_512_b64 = blake2b_512_file_b64(*FILEHANDLE);
$blake2b_512_b64u = blake2b_512_file_b64u(*FILEHANDLE);
### OO interface:
use Crypt::Digest::BLAKE2b_512;
$d = Crypt::Digest::BLAKE2b_512->new;
$d->add('any data');
$d->addfile('filename.dat');
$d->addfile(*FILEHANDLE);
$result_raw = $d->digest; # raw bytes
$result_hex = $d->hexdigest; # hexadecimal form
$result_b64 = $d->b64digest; # Base64 form
$result_b64u = $d->b64udigest; # Base64 URL Safe form
=head1 DESCRIPTION
Provides an interface to the BLAKE2b_512 digest algorithm.
=head1 EXPORT
Nothing is exported by default.
You can export selected functions:
use Crypt::Digest::BLAKE2b_512 qw(blake2b_512 blake2b_512_hex blake2b_512_b64 blake2b_512_b64u
blake2b_512_file blake2b_512_file_hex blake2b_512_file_b64 blake2b_512_file_b64u);
Or all of them at once:
use Crypt::Digest::BLAKE2b_512 ':all';
=head1 FUNCTIONS
=head2 blake2b_512
Logically joins all arguments into a single string, and returns its BLAKE2b_512 digest encoded as a binary string.
$blake2b_512_raw = blake2b_512('data string');
#or
$blake2b_512_raw = blake2b_512('any data', 'more data', 'even more data');
=head2 blake2b_512_hex
Logically joins all arguments into a single string, and returns its BLAKE2b_512 digest encoded as a hexadecimal string.
$blake2b_512_hex = blake2b_512_hex('data string');
#or
$blake2b_512_hex = blake2b_512_hex('any data', 'more data', 'even more data');
=head2 blake2b_512_b64
Logically joins all arguments into a single string, and returns its BLAKE2b_512 digest encoded as a Base64 string, B<with> trailing '=' padding.
$blake2b_512_b64 = blake2b_512_b64('data string');
#or
$blake2b_512_b64 = blake2b_512_b64('any data', 'more data', 'even more data');
=head2 blake2b_512_b64u
Logically joins all arguments into a single string, and returns its BLAKE2b_512 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).
$blake2b_512_b64url = blake2b_512_b64u('data string');
#or
$blake2b_512_b64url = blake2b_512_b64u('any data', 'more data', 'even more data');
=head2 blake2b_512_file
Reads file (defined by filename or filehandle) content, and returns its BLAKE2b_512 digest encoded as a binary string.
$blake2b_512_raw = blake2b_512_file('filename.dat');
#or
$blake2b_512_raw = blake2b_512_file(*FILEHANDLE);
=head2 blake2b_512_file_hex
Reads file (defined by filename or filehandle) content, and returns its BLAKE2b_512 digest encoded as a hexadecimal string.
$blake2b_512_hex = blake2b_512_file_hex('filename.dat');
#or
$blake2b_512_hex = blake2b_512_file_hex(*FILEHANDLE);
B<BEWARE:> You have to make sure that the filehandle is in binary mode before you pass it as argument to the addfile() method.
=head2 blake2b_512_file_b64
Reads file (defined by filename or filehandle) content, and returns its BLAKE2b_512 digest encoded as a Base64 string, B<with> trailing '=' padding.
$blake2b_512_b64 = blake2b_512_file_b64('filename.dat');
#or
$blake2b_512_b64 = blake2b_512_file_b64(*FILEHANDLE);
=head2 blake2b_512_file_b64u
Reads file (defined by filename or filehandle) content, and returns its BLAKE2b_512 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).
$blake2b_512_b64url = blake2b_512_file_b64u('filename.dat');
#or
$blake2b_512_b64url = blake2b_512_file_b64u(*FILEHANDLE);
