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);

     $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
