The protocol overview is available [here](https://github.com/trevp/axolotl/wiki), +and the details of the wire format are available [here](https://github.com/WhisperSystems/TextSecure/wiki/ProtocolV2). + +## PreKeys + +This protocol uses a concept called 'PreKeys'. A PreKey is an ECPublicKey and an associated unique +ID which are stored together by a server. PreKeys can also be signed. + +At install time, clients generate a single signed PreKey, as well as a large list of unsigned +PreKeys, and transmit all of them to the server. + +## Sessions + +The axolotl protocol is session-oriented. Clients establish a "session," which is then used for +all subsequent encrypt/decrypt operations. There is no need to ever tear down a session once one +has been established. + +Sessions are established in one of three ways: + +1. PreKeyBundles. A client that wishes to send a message to a recipient can establish a session by + retrieving a PreKeyBundle for that recipient from the server. +1. PreKeyWhisperMessages. A client can receive a PreKeyWhisperMessage from a recipient and use it + to establish a session. +1. KeyExchangeMessages. Two clients can exchange KeyExchange messages to establish a session. + +## State + +An established session encapsulates a lot of state between two clients. That state is maintained +in durable records which need to be kept for the life of the session. + +State is kept in the following places: + +1. Identity State. Clients will need to maintain the state of their own identity key pair, as well + as identity keys received from other clients. +1. PreKey State. Clients will need to maintain the state of their generated PreKeys. +1. Signed PreKey States. Clients will need to maintain the state of their signed PreKeys. +1. Session State. Clients will need to maintain the state of the sessions they have established. + +# Using libaxolotl + +## Install time + +At install time, a libaxolotl client needs to generate its identity keys, registration id, and +prekeys. + + IdentityKeyPair identityKeyPair = KeyHelper.generateIdentityKeyPair(); + int registrationId = KeyHelper.generateRegistrationId(); + List<PreKeyRecord> preKeys = KeyHelper.generatePreKeys(startId, 100); + PreKeyRecord lastResortKey = KeyHelper.generateLastResortKey(); + SignedPreKeyRecord signedPreKey = KeyHelper.generateSignedPreKey(identityKeyPair, 5); + + // Store identityKeyPair somewhere durable and safe. + // Store registrationId somewhere durable and safe. + + // Store preKeys in PreKeyStore. + // Store signed prekey in SignedPreKeyStore. + +## Building a session + +A libaxolotl client needs to implement four interfaces: IdentityKeyStore, PreKeyStore, +SignedPreKeyStore, and SessionStore. These will manage loading and storing of identity, +prekeys, signed prekeys, and session state. + +Once those are implemented, building a session is fairly straightforward: + + SessionStore sessionStore = new MySessionStore(); + PreKeyStore preKeyStore = new MyPreKeyStore(); + SignedPreKeyStore signedPreKeyStore = new MySignedPreKeyStore(); + IdentityKeyStore identityStore = new MyIdentityKeyStore(); + + // Instantiate a SessionBuilder for a remote recipientId + deviceId tuple. + SessionBuilder sessionBuilder = new SessionBuilder(sessionStore, preKeyStore, signedPreKeyStore, + identityStore, recipientId, deviceId); + + // Build a session with a PreKey retrieved from the server. + sessionBuilder.process(retrievedPreKey); + + SessionCipher sessionCipher = new SessionCipher(sessionStore, recipientId, deviceId); + CiphertextMessage message = sessionCipher.encrypt("Hello world!".getBytes("UTF-8")); + + deliver(message.serialize()); diff --git a/build.gradle b/build.gradle new file mode 100644 index 00000000..2b623a3f --- /dev/null +++ b/build.gradle @@ -0,0 +1,44 @@ +buildscript { + repositories { + mavenCentral() + } + + dependencies { + classpath 'com.android.tools.build:gradle:0.14.2' + } +} + +apply plugin: 'com.android.library' + +repositories { + mavenCentral() +} + +dependencies { + compile 'com.google.protobuf:protobuf-java:2.5.0' +} + +android { + compileSdkVersion 21 + buildToolsVersion '21.1.1' + + compileOptions { + sourceCompatibility JavaVersion.VERSION_1_7 + targetCompatibility JavaVersion.VERSION_1_7 + } + + android { + sourceSets { + main { + jniLibs.srcDirs = ['libs'] + } + } + } + +} + +tasks.whenTaskAdded { task -> + if (task.name.equals("lint")) { + task.enabled = false + } +}
