NAME
Crypt::RSA::SS::PKCS1v15 - PKCS #1 v1.5 signatures.SYNOPSIS
my $pkcs = new Crypt::RSA::SS::PKCS1v15 ( Digest => 'MD5' ); my $signature = $pkcs->sign ( Message => $message, Key => $private, ) || die $pss->errstr; my $verify = $pkcs->verify ( Message => $message, Key => $key, Signature => $signature, ) || die $pss->errstr;
DESCRIPTION
This module implements PKCS #1 v1.5 signatures based on RSA. See [13] for details on the scheme.METHODS
new()
Constructor. Takes a hash as argument with the following key:
- Digest
- Name of the Message Digest algorithm. Three Digest algorithms are supported: MD2, MD5 and SHA1. Digest defaults to SHA1.
version()
Returns the version number of the module.
sign()
Computes a PKCS #1 v1.5 signature on a message with the private key of the signer. sign() takes a hash argument with the following mandatory keys:
- Message
- Message to be signed, a string of arbitrary length.
- Key
- Private key of the signer, a Crypt::RSA::Key::Private object.
verify()
Verifies a signature generated with sign(). Returns a true value on success and false on failure. $self->errstr is set to ``Invalid signature.'' or appropriate error on failure. verify() takes a hash argument with the following mandatory keys:
- Key
- Public key of the signer, a Crypt::RSA::Key::Public object.
- Message
- The original signed message, a string of arbitrary length.
- Signature
- Signature computed with sign(), a string.
