Crypt::OpenPGP::SessionKey - Encrypted Session Key
use Crypt::OpenPGP::SessionKey;
my $key_data = 'f' x 64; ## Not a very good key :)
my $skey = Crypt::OpenPGP::SessionKey->new( Key => $public_key, SymKey => $key_data, ); my $serialized = $skey->save;

Crypt::OpenPGP::SessionKey implements encrypted session key packets; these packets store public-key-encrypted key data that, when decrypted using the corresponding secret key, can be used to decrypt a block of ciphertext--that is, a Crypt::OpenPGP::Ciphertext object.
Creates a new encrypted session key packet object and returns that object. If there are no arguments in %arg, the object is created empty; this is used, for example in parse (below), to create an empty packet which is then filled from the data in the buffer.
If you wish to initialize a non-empty object, %arg can contain:
This argument is required (for a non-empty object).
This argument is required (for a non-empty object).
This argument is optional; by default Crypt::OpenPGP::Cipher will
use DES3
.
Serializes the session key packet and returns the string of octets.
parse($buffer)
Given $buffer, a Crypt::OpenPGP::Buffer object holding (or with offset pointing to) an encrypted session key packet, returns a new Crypt::OpenPGP::Ciphertext object, initialized with the data in the buffer.
decrypt($secret_key)
Given a secret key object $secret_key (an object of a subclass of Crypt::OpenPGP::Key::Public), decrypts and decodes the encrypted session key data. The key data includes the symmetric key itself, along with a one-octet ID of the symmetric cipher used to encrypt the message.
Returns a list containing two items: the symmetric key and the cipher algorithm ID. These are suitable for passing off to the decrypt method of a Crypt::OpenPGP::Ciphertext object to decrypt a block of encrypted data.
Returns the key ID of the public key used to encrypt the session key; this is necessary for finding the appropriate secret key to decrypt the key.
