=head1 NAME

Crypt::Digest::[%orig_name%] - [%info%]

=head1 SYNOPSIS

   ### Functional interface:
   use Crypt::Digest::[%orig_name%] qw( [%lc_name%] [%lc_name%]_hex [%lc_name%]_b64 [%lc_name%]_b64u
                                [%lc_name%]_file [%lc_name%]_file_hex [%lc_name%]_file_b64 [%lc_name%]_file_b64u );

   # calculate digest from string/buffer
   $[%lc_name%]_raw  = [%lc_name%]('data string');
   $[%lc_name%]_hex  = [%lc_name%]_hex('data string');
   $[%lc_name%]_b64  = [%lc_name%]_b64('data string');
   $[%lc_name%]_b64u = [%lc_name%]_b64u('data string');
   # calculate digest from file
   $[%lc_name%]_raw  = [%lc_name%]_file('filename.dat');
   $[%lc_name%]_hex  = [%lc_name%]_file_hex('filename.dat');
   $[%lc_name%]_b64  = [%lc_name%]_file_b64('filename.dat');
   $[%lc_name%]_b64u = [%lc_name%]_file_b64u('filename.dat');
   # calculate digest from filehandle
   $[%lc_name%]_raw  = [%lc_name%]_file(*FILEHANDLE);
   $[%lc_name%]_hex  = [%lc_name%]_file_hex(*FILEHANDLE);
   $[%lc_name%]_b64  = [%lc_name%]_file_b64(*FILEHANDLE);
   $[%lc_name%]_b64u = [%lc_name%]_file_b64u(*FILEHANDLE);

   ### OO interface:
   use Crypt::Digest::[%orig_name%];

   $d = Crypt::Digest::[%orig_name%]->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

=head1 DESCRIPTION

Provides an interface to the [%orig_name%] digest algorithm.

=head1 EXPORT

Nothing is exported by default.

You can export selected functions:

  use Crypt::Digest::[%orig_name%] qw([%lc_name%] [%lc_name%]_hex [%lc_name%]_b64 [%lc_name%]_b64u
                                      [%lc_name%]_file [%lc_name%]_file_hex [%lc_name%]_file_b64 [%lc_name%]_file_b64u);

Or all of them at once:

  use Crypt::Digest::[%orig_name%] ':all';

=head1 FUNCTIONS

=head2 [%lc_name%]

Logically joins all arguments into a single string, and returns its [%orig_name%] digest encoded as a binary string.

 $[%lc_name%]_raw = [%lc_name%]('data string');
 #or
 $[%lc_name%]_raw = [%lc_name%]('any data', 'more data', 'even more data');

=head2 [%lc_name%]_hex

Logically joins all arguments into a single string, and returns its [%orig_name%] digest encoded as a hexadecimal string.

 $[%lc_name%]_hex = [%lc_name%]_hex('data string');
 #or
 $[%lc_name%]_hex = [%lc_name%]_hex('any data', 'more data', 'even more data');

=head2 [%lc_name%]_b64

Logically joins all arguments into a single string, and returns its [%orig_name%] digest encoded as a Base64 string, B<with> trailing '=' padding.

 $[%lc_name%]_b64 = [%lc_name%]_b64('data string');
 #or
 $[%lc_name%]_b64 = [%lc_name%]_b64('any data', 'more data', 'even more data');

=head2 [%lc_name%]_b64u

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

 $[%lc_name%]_b64url = [%lc_name%]_b64u('data string');
 #or
 $[%lc_name%]_b64url = [%lc_name%]_b64u('any data', 'more data', 'even more data');

=head2 [%lc_name%]_file

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

 $[%lc_name%]_raw = [%lc_name%]_file('filename.dat');
 #or
 $[%lc_name%]_raw = [%lc_name%]_file(*FILEHANDLE);

=head2 [%lc_name%]_file_hex

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

 $[%lc_name%]_hex = [%lc_name%]_file_hex('filename.dat');
 #or
 $[%lc_name%]_hex = [%lc_name%]_file_hex(*FILEHANDLE);

B<BEWARE:> You have to make sure that the filehandle is in binary mode before you pass it as argument to the addfile() method.

=head2 [%lc_name%]_file_b64

Reads file (defined by filename or filehandle) content, and returns its [%orig_name%] digest encoded as a Base64 string, B<with> trailing '=' padding.

 $[%lc_name%]_b64 = [%lc_name%]_file_b64('filename.dat');
 #or
 $[%lc_name%]_b64 = [%lc_name%]_file_b64(*FILEHANDLE);

=head2 [%lc_name%]_file_b64u

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

 $[%lc_name%]_b64url = [%lc_name%]_file_b64u('filename.dat');
 #or
 $[%lc_name%]_b64url = [%lc_name%]_file_b64u(*FILEHANDLE);

=head1 METHODS

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

 $d = Crypt::Digest::[%orig_name%]->new();

=head2 clone

 $d->clone();

=head2 reset

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

=head2 addfile

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

=head2 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);

=head2 hashsize

 $d->hashsize;
 #or
 Crypt::Digest::[%orig_name%]->hashsize();
 #or
 Crypt::Digest::[%orig_name%]::hashsize();

=head2 digest

 $result_raw = $d->digest();

=head2 hexdigest

 $result_hex = $d->hexdigest();

=head2 b64digest

 $result_b64 = $d->b64digest();
