Crypt::RSA::ES::PKCS1v15 - PKCS #1 v1.5 padded encryption scheme based on RSA.
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;
This module implements PKCS #1 v1.5 padded encryption scheme based on RSA. See [13] for details on the encryption scheme.
Constructor.
Returns the version number of the module.
Encrypts a string with a public key and returns the encrypted string on success. encrypt() takes a hash argument with the following mandatory keys:
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."
Public key of the recipient, a Crypt::RSA::Key::Public object.
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:
A string encrypted with encrypt(). The length of the cyphertext must be k octets, where k is the length of the RSA modulus.
Private key of the receiver, a Crypt::RSA::Key::Private object.
