DESCRIPTION
Provides an interface to the BLAKE2b_160 digest algorithm.
EXPORT
Nothing is exported by default.
You can export selected functions:
use Crypt::Digest::BLAKE2b_160 qw(blake2b_160 blake2b_160_hex blake2b_160_b64 blake2b_160_b64u blake2b_160_file blake2b_160_file_hex blake2b_160_file_b64 blake2b_160_file_b64u);
Or all of them at once:
use Crypt::Digest::BLAKE2b_160 ':all';
FUNCTIONS
blake2b_160
Logically joins all arguments into a single string, and returns its BLAKE2b_160 digest encoded as a binary string.
$blake2b_160_raw = blake2b_160('data string'); #or $blake2b_160_raw = blake2b_160('any data', 'more data', 'even more data');
blake2b_160_hex
Logically joins all arguments into a single string, and returns its BLAKE2b_160 digest encoded as a hexadecimal string.
$blake2b_160_hex = blake2b_160_hex('data string'); #or $blake2b_160_hex = blake2b_160_hex('any data', 'more data', 'even more data');
blake2b_160_b64
Logically joins all arguments into a single string, and returns its BLAKE2b_160 digest encoded as a Base64 string, with trailing '=' padding.
$blake2b_160_b64 = blake2b_160_b64('data string'); #or $blake2b_160_b64 = blake2b_160_b64('any data', 'more data', 'even more data');
blake2b_160_b64u
Logically joins all arguments into a single string, and returns its BLAKE2b_160 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).
$blake2b_160_b64url = blake2b_160_b64u('data string'); #or $blake2b_160_b64url = blake2b_160_b64u('any data', 'more data', 'even more data');
blake2b_160_file
Reads file (defined by filename or filehandle) content, and returns its BLAKE2b_160 digest encoded as a binary string.
$blake2b_160_raw = blake2b_160_file('filename.dat'); #or $blake2b_160_raw = blake2b_160_file(*FILEHANDLE);
blake2b_160_file_hex
Reads file (defined by filename or filehandle) content, and returns its BLAKE2b_160 digest encoded as a hexadecimal string.
$blake2b_160_hex = blake2b_160_file_hex('filename.dat'); #or $blake2b_160_hex = blake2b_160_file_hex(*FILEHANDLE);
BEWARE: You have to make sure that the filehandle is in binary mode before you pass it as argument to the addfile() method.
blake2b_160_file_b64
Reads file (defined by filename or filehandle) content, and returns its BLAKE2b_160 digest encoded as a Base64 string, with trailing '=' padding.
$blake2b_160_b64 = blake2b_160_file_b64('filename.dat'); #or $blake2b_160_b64 = blake2b_160_file_b64(*FILEHANDLE);
blake2b_160_file_b64u
Reads file (defined by filename or filehandle) content, and returns its BLAKE2b_160 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).
$blake2b_160_b64url = blake2b_160_file_b64u('filename.dat'); #or $blake2b_160_b64url = blake2b_160_file_b64u(*FILEHANDLE);
METHODS
The OO interface provides the same set of functions as Crypt::Digest.

$d = Crypt::Digest::BLAKE2b_160->new();
clone
$d->clone();
reset
$d->reset();
add
$d->add('any data'); #or $d->add('any data', 'more data', 'even more data');
addfile
$d->addfile('filename.dat'); #or $d->addfile(*FILEHANDLE);
add_bits
$d->add_bits($bit_string); # e.g. $d->add_bits("111100001010"); #or $d->add_bits($data, $nbits); # e.g. $d->add_bits("\xF0\xA0", 16);
hashsize
$d->hashsize; #or Crypt::Digest::BLAKE2b_160->hashsize(); #or Crypt::Digest::BLAKE2b_160::hashsize();
digest
$result_raw = $d->digest();
hexdigest
$result_hex = $d->hexdigest();
b64digest
