Crypt::RSA::SS::PKCS1vUser)Contributed Perl DocumenCrypt::RSA::SS::PKCS1v15(3)NAMECrypt::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.
METHODSnew()
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 signa-
ture." 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.
ERROR HANDLING
See ERROR HANDLING in Crypt::RSA(3) manpage.
