Crypt::RSA::ES::PKCS1v15 - PKCS #1 v1.5 padded encryption scheme based on RSA.

my $pkcs = new Crypt::RSA::ES::PKCS1v15;

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:

**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.

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.
