[][src]Enum sequoia_openpgp::packet::PKESK

#[non_exhaustive]pub enum PKESK {

Holds an asymmetrically encrypted session key.

The session key is used to decrypt the actual ciphertext, which is typically stored in a SEIP or AED packet. See Section 5.1 of RFC 4880 for details.

A PKESK packet is not normally instantiated directly. In most cases, you'll create one as a side-effect of encrypting a message using the streaming serializer, or parsing an encrypted message using the PacketParser.

Note: This enum cannot be exhaustively matched to allow future extensions.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

PKESK packet version 3.


impl PKESK[src]

pub fn version(&self) -> u8[src]

Gets the version.

Methods from Deref<Target = PKESK3>

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(
    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.
