29=head1 NAME
30
31Crypt::Cipher - Generic interface to cipher functions
32
33=head1 SYNOPSIS
34
35 #### example 1 (encrypting single block)
36 use Crypt::Cipher;
37
38 my $key = '...'; # length has to be valid key size for this cipher
39 my $c = Crypt::Cipher->new('AES', $key);
40 my $blocksize = $c->blocksize;
41 my $ciphertext = $c->encrypt('plain text block'); #encrypt 1 block
42 my $plaintext = $c->decrypt($ciphertext); #decrypt 1 block
43
44 ### example 2 (using CBC mode)
45 use Crypt::Mode::CBC;
46
47 my $key = '...'; # length has to be valid key size for this cipher
48 my $iv = '...'; # 16 bytes
49 my $cbc = Crypt::Mode::CBC->new('AES');
50 my $ciphertext = $cbc->encrypt("secret data", $key, $iv);
51
52 #### example 3 (compatibility with Crypt::CBC)
53 use Crypt::CBC;
54 use Crypt::Cipher;
55
56 my $key = '...'; # length has to be valid key size for this cipher
57 my $iv = '...'; # 16 bytes
58 my $cipher = Crypt::Cipher('AES', $key);
59 my $cbc = Crypt::CBC->new( -cipher=>$cipher, -iv=>$iv );
60 my $ciphertext = $cbc->encrypt("secret data");
61
62=head1 DESCRIPTION
63
64Provides an interface to various symmetric cipher algorithms.
65
66B<BEWARE:> This module implements just elementary "one-block-(en|de)cryption" operation - if you want to
67encrypt/decrypt generic data you have to use some of the cipher block modes - check for example
68L<Crypt::Mode::CBC|Crypt::Mode::CBC>, L<Crypt::Mode::CTR|Crypt::Mode::CTR> or L<Crypt::CBC|Crypt::CBC> (which will be slower).
69
70=head1 METHODS
71
72=head2 new
73
74Constructor, returns a reference to the cipher object.
75
76 ## basic scenario
77 $d = Crypt::Cipher->new($name, $key);
78 # $name = one of 'AES', 'Anubis', 'Blowfish', 'CAST5', 'Camellia', 'DES', 'DES_EDE',
79 # 'KASUMI', 'Khazad', 'MULTI2', 'Noekeon', 'RC2', 'RC5', 'RC6',
80 # 'SAFERP', 'SAFER_K128', 'SAFER_K64', 'SAFER_SK128', 'SAFER_SK64',
81 # 'SEED', 'Skipjack', 'Twofish', 'XTEA', 'IDEA', 'Serpent'
82 # simply any <NAME> for which there exists Crypt::Cipher::<NAME>
83 # $key = binary key (keysize should comply with selected cipher requirements)
84
85 ## some of the ciphers (e.g. MULTI2, RC5, SAFER) allow one to set number of rounds
86 $d = Crypt::Cipher->new('MULTI2', $key, $rounds);
87 # $rounds = positive integer (should comply with selected cipher requirements)
88
89=head2 encrypt
90
91Encrypts $plaintext and returns the $ciphertext where $plaintext and $ciphertext should be of B<blocksize> bytes.
92
93 $ciphertext = $d->encrypt($plaintext);
94
95=head2 decrypt
96
97Decrypts $ciphertext and returns the $plaintext where $plaintext and $ciphertext should be of B<blocksize> bytes.
98
99 $plaintext = $d->decrypt($ciphertext);
100
101=head2 keysize
102
103Just an alias for B<max_keysize> (needed for L<Crypt::CBC|Crypt::CBC> compatibility).
104
105=head2 max_keysize
106
107Returns the maximal allowed key size (in bytes) for given cipher.
108
109 $d->max_keysize;
110 #or
111 Crypt::Cipher->max_keysize('AES');
112 #or
113 Crypt::Cipher::max_keysize('AES');
114
115=head2 min_keysize
116
117Returns the minimal allowed key size (in bytes) for given cipher.
118
119 $d->min_keysize;
120 #or
121 Crypt::Cipher->min_keysize('AES');
122 #or
123 Crypt::Cipher::min_keysize('AES');
124
125=head2 blocksize
126
127Returns block size (in bytes) for given cipher.
128
129 $d->blocksize;
130 #or
131 Crypt::Cipher->blocksize('AES');
132 #or
133 Crypt::Cipher::blocksize('AES');
134
135=head2 default_rounds
136
137Returns default number of rounds for given cipher. NOTE: only some ciphers (e.g. MULTI2, RC5, SAFER) allow one to set number of rounds via new().
138
139 $d->default_rounds;
140 #or
141 Crypt::Cipher->default_rounds('AES');
142 #or
143 Crypt::Cipher::default_rounds('AES');
