[−][src]Struct sequoia_openpgp::packet::skesk::SKESK4
Holds an symmetrically encrypted session key version 4.
Holds an symmetrically encrypted session key. The session key is needed to decrypt the actual ciphertext. See Section 5.3 of RFC 4880 for details.
Implementations
impl SKESK4
[src]
pub fn new(
esk_algo: SymmetricAlgorithm,
s2k: S2K,
esk: Option<Box<[u8]>>
) -> Result<SKESK4>
[src]
esk_algo: SymmetricAlgorithm,
s2k: S2K,
esk: Option<Box<[u8]>>
) -> Result<SKESK4>
Creates a new SKESK version 4 packet.
The given symmetric algorithm is the one used to encrypt the session key.
pub fn with_password(
payload_algo: SymmetricAlgorithm,
esk_algo: SymmetricAlgorithm,
s2k: S2K,
session_key: &SessionKey,
password: &Password
) -> Result<SKESK4>
[src]
payload_algo: SymmetricAlgorithm,
esk_algo: SymmetricAlgorithm,
s2k: S2K,
session_key: &SessionKey,
password: &Password
) -> Result<SKESK4>
Creates a new SKESK4 packet with the given password.
This function takes two SymmetricAlgorithm
arguments: The
first, payload_algo
, is the algorithm used to encrypt the
message's payload (i.e. the one used in the SEIP
or
AED
packet), and the second, esk_algo
, is used to
encrypt the session key. Usually, one should use the same
algorithm, but if they differ, the esk_algo
should be at
least as strong as the payload_algo
as not to weaken the
security of the payload encryption.
pub fn symmetric_algo(&self) -> SymmetricAlgorithm
[src]
Gets the symmetric encryption algorithm.
pub fn set_symmetric_algo(
&mut self,
algo: SymmetricAlgorithm
) -> SymmetricAlgorithm
[src]
&mut self,
algo: SymmetricAlgorithm
) -> SymmetricAlgorithm
Sets the symmetric encryption algorithm.
pub fn s2k(&self) -> &S2K
[src]
Gets the key derivation method.
pub fn set_s2k(&mut self, s2k: S2K) -> S2K
[src]
Sets the key derivation method.
pub fn esk(&self) -> Result<Option<&[u8]>>
[src]
Gets the encrypted session key.
If the S2K
mechanism is not supported by Sequoia, this
function will fail. Note that the information is not lost,
but stored in the packet. If the packet is serialized again,
it is written out.
pub fn set_esk(&mut self, esk: Option<Box<[u8]>>) -> Option<Box<[u8]>>
[src]
Sets the encrypted session key.
pub fn decrypt(
&self,
password: &Password
) -> Result<(SymmetricAlgorithm, SessionKey)>
[src]
&self,
password: &Password
) -> Result<(SymmetricAlgorithm, SessionKey)>
Derives the key inside this SKESK4 from password
.
Returns a tuple of the symmetric cipher to use with the key and the key itself.
