Crypt::Digest::BLAKE2s_160 - Hash function BLAKE2s [size: 160 bits]
SYNOPSIS
### Functional interface: use Crypt::Digest::BLAKE2s_160 qw( blake2s_160 blake2s_160_hex blake2s_160_b64 blake2s_160_b64u blake2s_160_file blake2s_160_file_hex blake2s_160_file_b64 blake2s_160_file_b64u ); # calculate digest from string/buffer $blake2s_160_raw = blake2s_160('data string'); $blake2s_160_hex = blake2s_160_hex('data string'); $blake2s_160_b64 = blake2s_160_b64('data string'); $blake2s_160_b64u = blake2s_160_b64u('data string'); # calculate digest from file $blake2s_160_raw = blake2s_160_file('filename.dat'); $blake2s_160_hex = blake2s_160_file_hex('filename.dat'); $blake2s_160_b64 = blake2s_160_file_b64('filename.dat'); $blake2s_160_b64u = blake2s_160_file_b64u('filename.dat'); # calculate digest from filehandle $blake2s_160_raw = blake2s_160_file(*FILEHANDLE); $blake2s_160_hex = blake2s_160_file_hex(*FILEHANDLE); $blake2s_160_b64 = blake2s_160_file_b64(*FILEHANDLE); $blake2s_160_b64u = blake2s_160_file_b64u(*FILEHANDLE); ### OO interface: use Crypt::Digest::BLAKE2s_160; $d = Crypt::Digest::BLAKE2s_160->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
DESCRIPTION
Provides an interface to the BLAKE2s_160 digest algorithm.
EXPORT
Nothing is exported by default. You can export selected functions: use Crypt::Digest::BLAKE2s_160 qw(blake2s_160 blake2s_160_hex blake2s_160_b64 blake2s_160_b64u blake2s_160_file blake2s_160_file_hex blake2s_160_file_b64 blake2s_160_file_b64u); Or all of them at once: use Crypt::Digest::BLAKE2s_160 ':all';
FUNCTIONS
blake2s_160 Logically joins all arguments into a single string, and returns its BLAKE2s_160 digest encoded as a binary string. $blake2s_160_raw = blake2s_160('data string'); #or $blake2s_160_raw = blake2s_160('any data', 'more data', 'even more data'); blake2s_160_hex Logically joins all arguments into a single string, and returns its BLAKE2s_160 digest encoded as a hexadecimal string. $blake2s_160_hex = blake2s_160_hex('data string'); #or $blake2s_160_hex = blake2s_160_hex('any data', 'more data', 'even more data'); blake2s_160_b64 Logically joins all arguments into a single string, and returns its BLAKE2s_160 digest encoded as a Base64 string, with trailing '=' padding. $blake2s_160_b64 = blake2s_160_b64('data string'); #or $blake2s_160_b64 = blake2s_160_b64('any data', 'more data', 'even more data'); blake2s_160_b64u Logically joins all arguments into a single string, and returns its BLAKE2s_160 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5). $blake2s_160_b64url = blake2s_160_b64u('data string'); #or $blake2s_160_b64url = blake2s_160_b64u('any data', 'more data', 'even more data'); blake2s_160_file Reads file (defined by filename or filehandle) content, and returns its BLAKE2s_160 digest encoded as a binary string. $blake2s_160_raw = blake2s_160_file('filename.dat'); #or $blake2s_160_raw = blake2s_160_file(*FILEHANDLE); blake2s_160_file_hex Reads file (defined by filename or filehandle) content, and returns its BLAKE2s_160 digest encoded as a hexadecimal string. $blake2s_160_hex = blake2s_160_file_hex('filename.dat'); #or $blake2s_160_hex = blake2s_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. blake2s_160_file_b64 Reads file (defined by filename or filehandle) content, and returns its BLAKE2s_160 digest encoded as a Base64 string, with trailing '=' padding. $blake2s_160_b64 = blake2s_160_file_b64('filename.dat'); #or $blake2s_160_b64 = blake2s_160_file_b64(*FILEHANDLE); blake2s_160_file_b64u Reads file (defined by filename or filehandle) content, and returns its BLAKE2s_160 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5). $blake2s_160_b64url = blake2s_160_file_b64u('filename.dat'); #or $blake2s_160_b64url = blake2s_160_file_b64u(*FILEHANDLE);
METHODS
The OO interface provides the same set of functions as Crypt::Digest. new $d = Crypt::Digest::BLAKE2s_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::BLAKE2s_160->hashsize(); #or Crypt::Digest::BLAKE2s_160::hashsize(); digest $result_raw = $d->digest(); hexdigest $result_hex = $d->hexdigest(); b64digest $result_b64 = $d->b64digest(); b64udigest $result_b64url = $d->b64udigest();
