Implementations

source

impl Session

source

pub async fn decrypt(
&mut self,
message: &OlmMessage
) -> Result<String, DecryptionError>

Decrypt the given Olm message.

Returns the decrypted plaintext or an DecrypitonError if decryption failed.

Arguments

message - The Olm message that should be decrypted.

source

pub fn sender_key(&self) -> Curve25519PublicKey

Get the sender key that was used to establish this Session.

source

pub async fn encrypt(
 &mut self,
 recipient_device: &ReadOnlyDevice,
 content: AnyToDeviceEventContent
) -> Result<ToDeviceRoomEncryptedEventContent, OlmError>

Encrypt the given event content content as an m.room.encrypted event content.

Arguments

recipient_device - The device for which this message is going to be encrypted, this needs to be the device that was used to create this session with.
content - The content of the event.

source

pub fn session_id(&self) -> &str

Returns the unique identifier for this session.

source

pub async fn pickle(&self) -> PickledSession

Store the session as a base64 encoded string.

Arguments

pickle_mode - The mode that was used to pickle the session, either an unencrypted mode or an encrypted using passphrase.

source

pub fn from_pickle(
 user_id: Arc<UserId>,
 device_id: Arc<DeviceId>,
 our_identity_keys: Arc<IdentityKeys>,
 pickle: PickledSession
) -> Self

Restore a Session from a previously pickled string.

Returns the restored Olm Session or a SessionUnpicklingError if there was an error.

Arguments

user_id - Our own user id that the session belongs to.
device_id - Our own device ID that the session belongs to.
our_idenity_keys - An clone of the Arc to our own identity keys.
pickle - The pickled version of the Session.
pickle_mode - The mode that was used to pickle the session, either an unencrypted mode or an encrypted using passphrase.
