NAME

6       Crypt::RSA::SS::PKCS1v15 - PKCS #1 v1.5 signatures.

SYNOPSIS

9           my $pkcs = new Crypt::RSA::SS::PKCS1v15 (
10                               Digest => 'MD5'
11                           );
12
13           my $signature = $pkcs->sign (
14                               Message => $message,
15                               Key     => $private,
16                           ) || die $pss->errstr;
17
18           my $verify    = $pkcs->verify (
19                               Message   => $message,
20                               Key       => $key,
21                               Signature => $signature,
22                           ) || die $pss->errstr;

DESCRIPTION

25       This module implements PKCS #1 v1.5 signatures based on RSA. See [13]
26       for details on the scheme.
27

METHODS

29   new()
30       Constructor.   Takes a hash as argument with the following key:
31
32       Digest
33           Name of the Message Digest algorithm. Three Digest algorithms are
34           supported: MD2, MD5 and SHA1. Digest defaults to SHA1.
35
36   version()
37       Returns the version number of the module.
38
39   sign()
40       Computes a PKCS #1 v1.5 signature on a message with the private key of
41       the signer. sign() takes a hash argument with the following mandatory
42       keys:
43
44       Message
45           Message to be signed, a string of arbitrary length.
46
47       Key Private key of the signer, a Crypt::RSA::Key::Private object.
48
49   verify()
50       Verifies a signature generated with sign(). Returns a true value on
51       success and false on failure. $self->errstr is set to "Invalid
52       signature."  or appropriate error on failure. verify() takes a hash
53       argument with the following mandatory keys:
54
55       Key Public key of the signer, a Crypt::RSA::Key::Public object.
56
57       Message
58           The original signed message, a string of arbitrary length.
59
60       Signature
61           Signature computed with sign(), a string.
