Crypt::Checksum::Adler32(3)

NAME
Crypt::Checksum::Adler32 - Compute Adler32 checksum

SYNOPSIS
   use Crypt::Checksum::Adler32;

   $d = Crypt::Checksum::Adler32->new;
   $d->add('any data');
   $d->addfile('filename.dat');
   $d->addfile(*FILEHANDLE);
   $checksum_raw  = $d->digest;     # raw bytes
   $checksum_hex  = $d->hexdigest;  # hexadecimal form

DESCRIPTION
Calculating Adler32 checksums (OO interface);

Since: CryptX-0.032

METHODS

  new
Constructor, returns a reference to the checksum object.

 $d = Crypt::Checksum::Adler32->new;

  clone
Creates a copy of the checksum object state and returns a reference to the copy.

 $d->clone();

  reset
Reinitialize the checksum object state and returns a reference to the checksum object.

 $d->reset();

  add
All arguments are appended to the message we calculate checksum for. The return value is the checksum object itself.

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

  addfile
The content of the file (or filehandle) is appended to the message we calculate checksum for. The return value is the checksum object itself.

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

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

  digest
Returns the binary checksum (raw bytes).

 $result_raw = $d->digest();

  hexdigest
Returns the checksum encoded as a hexadecimal string.

 $result_hex = $d->hexdigest();
