Struct vodozemac::olm::Account

pub struct Account { /* private fields */ }

An Olm account manages all cryptographic keys used on a device.

Implementations

impl Account

pub fn new() -> Self

Create a new Account with new random identity keys.

pub fn identity_keys(&self) -> IdentityKeys

Get the IdentityKeys of this Account

pub fn ed25519_key(&self) -> Ed25519PublicKey

Get a reference to the account’s public Ed25519 key

pub fn curve25519_key(&self) -> &Curve25519PublicKey

Get a reference to the account’s public Curve25519 key

pub fn curve25519_key_encoded(&self) -> &str

Get a reference to the account’s public Curve25519 key as an unpadded base64-encoded string.

pub fn sign(&self, message: &str) -> Ed25519Signature

Sign the given message using our Ed25519 fingerprint key.

pub fn max_number_of_one_time_keys(&self) -> usize

Get the maximum number of one-time keys the client should keep on the server.

Note: this differs from the libolm method of the same name, the libolm method returned the maximum amount of one-time keys the Account could hold and only half of those should be uploaded.

pub fn create_outbound_session(
    &self,
    identity_key: Curve25519PublicKey,
    one_time_key: Curve25519PublicKey
) -> Session

Create a Session with the given identity key and one-time key.

pub fn remove_one_time_key(
    &mut self,
    public_key: &Curve25519PublicKey
) -> Option<Curve25519SecretKey>

Remove a one-time key that has previously been published but not yet used.

Note: This function is only rarely useful and you’ll know if you need it. Notably, you do not need to call it manually when using up a key via Account::create_inbound_session since the key is automatically removed in that case.

pub fn create_inbound_session(
    &mut self,
    their_identity_key: &Curve25519PublicKey,
    pre_key_message: &PreKeyMessage
) -> Result<InboundCreationResult, SessionCreationError>

Create a Session from the given pre-key message and identity key

pub fn generate_one_time_keys(&mut self, count: usize)

Generates the supplied number of one time keys.

pub fn one_time_keys(&self) -> HashMap<KeyId, Curve25519PublicKey>

Get the currently unpublished one-time keys.

The one-time keys should be published to a server and marked as published using the mark_keys_as_published() method.

pub fn one_time_keys_encoded(&self) -> HashMap<String, String>

Get the currently unpublished one-time keys in base64-encoded form.

The one-time keys should be published to a server and marked as published using the mark_keys_as_published() method.

pub fn generate_fallback_key(&mut self)

Generate a single new fallback key.

The fallback key will be used by other users to establish a Session if all the one-time keys on the server have been used up.

pub fn fallback_key(&self) -> HashMap<KeyId, Curve25519PublicKey>

Get the currently unpublished fallback key.

The fallback key should be published just like the one-time keys, after it has been successfully published it needs to be marked as published using the mark_keys_as_published() method as well.

pub fn forget_fallback_key(&mut self) -> bool

The Account stores at most two private parts of the fallback key. This method lets us forget the previously used fallback key.

pub fn mark_keys_as_published(&mut self)

Mark all currently unpublished one-time and fallback keys as published.

pub fn pickle(&self) -> AccountPickle

Convert the account into a struct which implements serde::Serialize and serde::Deserialize.

pub fn from_pickle(pickle: AccountPickle) -> Self

Restore an Account from a previously saved AccountPickle.

pub fn from_libolm_pickle(
    pickle: &str,
    pickle_key: &str
) -> Result<Self, LibolmPickleError>

Available on crate feature libolm-compat only.

Create an Account object by unpickling an account pickle in libolm legacy pickle format.

Such pickles are encrypted and need to first be decrypted using pickle_key.

Trait Implementations

impl Default for Account

fn default() -> Self

Returns the “default value” for a type.

impl From<AccountPickle> for Account

fn from(pickle: AccountPickle) -> Self

Converts to this type from the input type.
