10
11 $d = Crypt::Checksum::Adler32->new;
12 $d->add('any data');
13 $d->addfile('filename.dat');
14 $d->addfile(*FILEHANDLE);

17
19 Calculating Adler32 checksums (OO interface);
20
21 Since: CryptX-0.032
22
24 new
25 Constructor, returns a reference to the checksum object.
26
27 $d = Crypt::Checksum::Adler32->new;
28
29 clone
30 Creates a copy of the checksum object state and returns a reference to
31 the copy.
32
33 $d->clone();
34
35 reset
36 Reinitialize the checksum object state and returns a reference to the
37 checksum object.
38
39 $d->reset();
40
41 add
42 All arguments are appended to the message we calculate checksum for.
43 The return value is the checksum object itself.
44
45 $d->add('any data');
46 #or
47 $d->add('any data', 'more data', 'even more data');
48
49 addfile
50 The content of the file (or filehandle) is appended to the message we
51 calculate checksum for. The return value is the checksum object
52 itself.
53
54 $d->addfile('filename.dat');
55 #or
56 $d->addfile(*FILEHANDLE);
57
58 BEWARE: You have to make sure that the filehandle is in binary mode
59 before you pass it as argument to the addfile() method.
60
61 digest
62 Returns the binary checksum (raw bytes).
63
64 $result_raw = $d->digest();
65
66 hexdigest
67 Returns the checksum encoded as a hexadecimal string.
68
69 $result_hex = $d->hexdigest();
