Crypt::RSA::ES::PKCS1vUser)Contributed Perl DocumenCrypt::RSA::ES::PKCS1v15(3)NAMECrypt::RSA::ES::PKCS1v15 - PKCS #1 v1.5 padded encryption scheme based
on RSA.
SYNOPSIS
my $pkcs = new Crypt::RSA::ES::PKCS1v15;
my $ct = $pkcs->encrypt( Key => $key, Message => $message ) ||
die $pkcs->errstr;
my $pt = $pkcs->decrypt( Key => $key, Cyphertext => $ct ) ||
die $pkcs->errstr;
DESCRIPTION
This module implements PKCS #1 v1.5 padded encryption scheme based on
RSA. See [13] for details on the encryption scheme.
METHODSnew()
Constructor.
version()
Returns the version number of the module.
encrypt()
Encrypts a string with a public key and returns the encrypted string on
success. encrypt() takes a hash argument with the following mandatory
keys:
Message
A string to be encrypted. The length of this string should not
exceed k-10 octets, where k is the octet length of the RSA modulus.
If Message is longer than k-10, the method will fail and set
$self->errstr to "Message too long."
Key Public key of the recipient, a Crypt::RSA::Key::Public object.
decrypt()
Decrypts cyphertext with a private key and returns plaintext on
success. $self->errstr is set to "Decryption Error." or appropriate
error on failure. decrypt() takes a hash argument with the following
mandatory keys:
Cyphertext
A string encrypted with encrypt(). The length of the cyphertext
must be k octets, where k is the length of the RSA modulus.
Key Private key of the receiver, a Crypt::RSA::Key::Private object.
ERROR HANDLING
