[−][src]Struct sequoia_openpgp::packet::pkesk::PKESK3
Holds an asymmetrically encrypted session key.
The session key is needed to decrypt the actual ciphertext. See Section 5.1 of RFC 4880 for details.
Implementations
impl PKESK3
[src]
pub fn new(
recipient: KeyID,
pk_algo: PublicKeyAlgorithm,
encrypted_session_key: Ciphertext
) -> Result<PKESK3>
[src]
recipient: KeyID,
pk_algo: PublicKeyAlgorithm,
encrypted_session_key: Ciphertext
) -> Result<PKESK3>
Creates a new PKESK3 packet.
pub fn for_recipient<P, R>(
algo: SymmetricAlgorithm,
session_key: &SessionKey,
recipient: &Key<P, R>
) -> Result<PKESK3> where
P: KeyParts,
R: KeyRole,
[src]
algo: SymmetricAlgorithm,
session_key: &SessionKey,
recipient: &Key<P, R>
) -> Result<PKESK3> where
P: KeyParts,
R: KeyRole,
Creates a new PKESK3 packet for the given recipent.
The given symmetric algorithm must match the algorithm that is used to encrypt the payload.
pub fn recipient(&self) -> &KeyID
[src]
Gets the recipient.
pub fn set_recipient(&mut self, recipient: KeyID) -> KeyID
[src]
Sets the recipient.
pub fn pk_algo(&self) -> PublicKeyAlgorithm
[src]
Gets the public key algorithm.
pub fn set_pk_algo(&mut self, algo: PublicKeyAlgorithm) -> PublicKeyAlgorithm
[src]
Sets the public key algorithm.
pub fn esk(&self) -> &Ciphertext
[src]
Gets the encrypted session key.
pub fn set_esk(&mut self, esk: Ciphertext) -> Ciphertext
[src]
Sets the encrypted session key.
pub fn decrypt(
&self,
decryptor: &mut dyn Decryptor,
sym_algo_hint: Option<SymmetricAlgorithm>
) -> Option<(SymmetricAlgorithm, SessionKey)>
[src]
&self,
decryptor: &mut dyn Decryptor,
sym_algo_hint: Option<SymmetricAlgorithm>
) -> Option<(SymmetricAlgorithm, SessionKey)>
Decrypts the encrypted session key.
If the symmetric algorithm used to encrypt the message is known in advance, it should be given as argument. This allows us to reduce the side-channel leakage of the decryption operation for RSA.
Returns the session key and symmetric algorithm used to encrypt the following payload.
Returns None
on errors. This prevents leaking information
to an attacker, which could lead to compromise of secret key
material with certain algorithms (RSA). See Section 14 of
RFC 4880.
