Crypt::Digest::SHA3_512 - Hash function SHA3-512 [size: 512 bits]

   ### Functional interface:
   use Crypt::Digest::SHA3_512 qw( sha3_512 sha3_512_hex sha3_512_b64 sha3_512_b64u
                                sha3_512_file sha3_512_file_hex sha3_512_file_b64 sha3_512_file_b64u );
   # calculate digest from string/buffer
   $sha3_512_raw  = sha3_512('data string');
   $sha3_512_hex  = sha3_512_hex('data string');
   $sha3_512_b64  = sha3_512_b64('data string');
   $sha3_512_b64u = sha3_512_b64u('data string');
   # calculate digest from file
   $sha3_512_raw  = sha3_512_file('filename.dat');
   $sha3_512_hex  = sha3_512_file_hex('filename.dat');
   $sha3_512_b64  = sha3_512_file_b64('filename.dat');
   $sha3_512_b64u = sha3_512_file_b64u('filename.dat');
   # calculate digest from filehandle
   $sha3_512_raw  = sha3_512_file(*FILEHANDLE);
   $sha3_512_hex  = sha3_512_file_hex(*FILEHANDLE);
   $sha3_512_b64  = sha3_512_file_b64(*FILEHANDLE);
   $sha3_512_b64u = sha3_512_file_b64u(*FILEHANDLE);
   ### OO interface:
   use Crypt::Digest::SHA3_512;
   $d = Crypt::Digest::SHA3_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

Provides an interface to the SHA3_512 digest algorithm.

Nothing is exported by default.

You can export selected functions:

  use Crypt::Digest::SHA3_512 qw(sha3_512 sha3_512_hex sha3_512_b64 sha3_512_b64u
                                      sha3_512_file sha3_512_file_hex sha3_512_file_b64 sha3_512_file_b64u);

Or all of them at once:

  use Crypt::Digest::SHA3_512 ':all';

Logically joins all arguments into a single string, and returns its SHA3_512 digest encoded as a binary string.

 $sha3_512_raw = sha3_512('data string');
 #or
 $sha3_512_raw = sha3_512('any data', 'more data', 'even more data');

Logically joins all arguments into a single string, and returns its SHA3_512 digest encoded as a hexadecimal string.

 $sha3_512_hex = sha3_512_hex('data string');
 #or
 $sha3_512_hex = sha3_512_hex('any data', 'more data', 'even more data');

Logically joins all arguments into a single string, and returns its SHA3_512 digest encoded as a Base64 string, with trailing '=' padding.

 $sha3_512_b64 = sha3_512_b64('data string');
 #or
 $sha3_512_b64 = sha3_512_b64('any data', 'more data', 'even more data');

Logically joins all arguments into a single string, and returns its SHA3_512 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).

 $sha3_512_b64url = sha3_512_b64u('data string');
 #or
 $sha3_512_b64url = sha3_512_b64u('any data', 'more data', 'even more data');

Reads file (defined by filename or filehandle) content, and returns its SHA3_512 digest encoded as a binary string.

 $sha3_512_raw = sha3_512_file('filename.dat');
 #or
 $sha3_512_raw = sha3_512_file(*FILEHANDLE);

Reads file (defined by filename or filehandle) content, and returns its SHA3_512 digest encoded as a hexadecimal string.

 $sha3_512_hex = sha3_512_file_hex('filename.dat');
 #or
 $sha3_512_hex = sha3_512_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.

Reads file (defined by filename or filehandle) content, and returns its SHA3_512 digest encoded as a Base64 string, with trailing '=' padding.

 $sha3_512_b64 = sha3_512_file_b64('filename.dat');
 #or
 $sha3_512_b64 = sha3_512_file_b64(*FILEHANDLE);

Reads file (defined by filename or filehandle) content, and returns its SHA3_512 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).

 $sha3_512_b64url = sha3_512_file_b64u('filename.dat');
 #or
 $sha3_512_b64url = sha3_512_file_b64u(*FILEHANDLE);

The OO interface provides the same set of functions as Crypt::Digest.

 $d = Crypt::Digest::SHA3_512->new();


 $d->clone();


 $d->reset();


 $d->add('any data');
 #or
 $d->add('any data', 'more data', 'even more data');


 $d->addfile('filename.dat');
 #or
 $d->addfile(*FILEHANDLE);


 $d->add_bits($bit_string);   # e.g. $d->add_bits("111100001010");
 #or
 $d->add_bits($data, $nbits); # e.g. $d->add_bits("\xF0\xA0", 16);


 $d->hashsize;
 #or
 Crypt::Digest::SHA3_512->hashsize();
 #or
 Crypt::Digest::SHA3_512::hashsize();


 $result_raw = $d->digest();


 $result_hex = $d->hexdigest();


 $result_b64 = $d->b64digest();


 $result_b64url = $d->b64udigest();
