NAME

Crypt::Digest::SHA384 - Hash function SHA-384 [size: 384 bits]

SYNOPSIS

   ### Functional interface:
   use Crypt::Digest::SHA384 qw( sha384 sha384_hex sha384_b64 sha384_b64u
                                sha384_file sha384_file_hex sha384_file_b64 sha384_file_b64u );

   # calculate digest from string/buffer
   $sha384_raw  = sha384('data string');
   $sha384_hex  = sha384_hex('data string');
   $sha384_b64  = sha384_b64('data string');
   $sha384_b64u = sha384_b64u('data string');
   # calculate digest from file
   $sha384_raw  = sha384_file('filename.dat');
   $sha384_hex  = sha384_file_hex('filename.dat');
   $sha384_b64  = sha384_file_b64('filename.dat');
   $sha384_b64u = sha384_file_b64u('filename.dat');
   # calculate digest from filehandle
   $sha384_raw  = sha384_file(*FILEHANDLE);
   $sha384_hex  = sha384_file_hex(*FILEHANDLE);
   $sha384_b64  = sha384_file_b64(*FILEHANDLE);
   $sha384_b64u = sha384_file_b64u(*FILEHANDLE);

   ### OO interface:
   use Crypt::Digest::SHA384;

   $d = Crypt::Digest::SHA384->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 SHA384 digest algorithm.

EXPORT

Nothing is exported by default.

You can export selected functions:

  use Crypt::Digest::SHA384 qw(sha384 sha384_hex sha384_b64 sha384_b64u
                                      sha384_file sha384_file_hex sha384_file_b64 sha384_file_b64u);

Or all of them at once:

  use Crypt::Digest::SHA384 ':all';

FUNCTIONS

sha384

Logically joins all arguments into a single string, and returns its SHA384 digest encoded as a binary string.

 $sha384_raw = sha384('data string');
 #or
 $sha384_raw = sha384('any data', 'more data', 'even more data');

sha384_hex

Logically joins all arguments into a single string, and returns its SHA384 digest encoded as a hexadecimal string.

 $sha384_hex = sha384_hex('data string');
 #or
 $sha384_hex = sha384_hex('any data', 'more data', 'even more data');

sha384_b64

Logically joins all arguments into a single string, and returns its SHA384 digest encoded as a Base64 string, with trailing '=' padding.

 $sha384_b64 = sha384_b64('data string');
 #or
 $sha384_b64 = sha384_b64('any data', 'more data', 'even more data');

sha384_b64u

Logically joins all arguments into a single string, and returns its SHA384 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).

 $sha384_b64url = sha384_b64u('data string');
 #or
 $sha384_b64url = sha384_b64u('any data', 'more data', 'even more data');

sha384_file

Reads file (defined by filename or filehandle) content, and returns its SHA384 digest encoded as a binary string.

 $sha384_raw = sha384_file('filename.dat');
 #or
 $sha384_raw = sha384_file(*FILEHANDLE);

sha384_file_hex

Reads file (defined by filename or filehandle) content, and returns its SHA384 digest encoded as a hexadecimal string.

 $sha384_hex = sha384_file_hex('filename.dat');
 #or
 $sha384_hex = sha384_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.

sha384_file_b64

Reads file (defined by filename or filehandle) content, and returns its SHA384 digest encoded as a Base64 string, with trailing '=' padding.

 $sha384_b64 = sha384_file_b64('filename.dat');
 #or
 $sha384_b64 = sha384_file_b64(*FILEHANDLE);

sha384_file_b64u

Reads file (defined by filename or filehandle) content, and returns its SHA384 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).

 $sha384_b64url = sha384_file_b64u('filename.dat');
 #or
 $sha384_b64url = sha384_file_b64u(*FILEHANDLE);
