Olm
|
|
===
|
|
|
|
Note: before using any of the olm functions, you must call `Olm.init()`, and
|
|
wait for the promise to resolve, otherwise you will get errors like:
|
|
`Uncaught TypeError: Olm.Account is not a constructor`
|
|
|
|
If you get errors about failure to compile the wasm file, it is likely that Olm
|
|
is not locating the wasm file properly. You can tell Olm where the wasm file
|
|
is by passing a `locateFile` parameter to `Olm.init()`, for example:
|
|
`Olm.init({locateFile: () => pathToWasmFile})`.
|
|
|
|
Example:
|
|
|
|
var alice = new Olm.Account();
|
|
var bob = new Olm.Account();
|
|
alice.create();
|
|
bob.create();
|
|
bob.generate_one_time_keys(1);
|
|
|
|
var bobs_id_keys = JSON.parse(bob.identity_keys());
|
|
var bobs_id_key = bobs_id_keys.curve25519;
|
|
var bobs_ot_keys = JSON.parse(bob.one_time_keys());
|
|
for (key in bobs_ot_keys.curve25519) {
|
|
var bobs_ot_key = bobs_ot_keys.curve25519[key];
|
|
}
|
|
|
|
alice_session = new Olm.Session();
|
|
alice_session.create_outbound(alice, bobs_id_key, bobs_ot_key);
|
|
alice_message = a_session.encrypt("Hello");
|
|
|
|
bob_session.create_inbound(bob, bob_message);
|
|
var plaintext = bob_session.decrypt(message_1.type, bob_message);
|
|
bob.remove_one_time_keys(bob_session);
|

Group chat:
|
|
|
|
var outbound_session = new Olm.OutboundGroupSession();
|
|
outbound_session.create();
|
|
|
|
// exchange these over a secure channel
|
|
var session_id = group_session.session_id();
|
|
var session_key = group_session.session_key();
|

var message_index = group_session.message_index();

var inbound_session = new Olm.InboundGroupSession();

inbound_session.create(message_index, session_key);

var ciphertext = outbound_session.encrypt("Hello");
