# libtextsecure-java
A Java library for communicating via TextSecure.
## Implementing the Axolotl interfaces
The axolotl encryption protocol is a stateful protocol, so libtextsecure users
need to implement the storage interface `AxolotlStore`, which handles load/store
of your key and session information to durable media.
## Creating keys
`````
IdentityKeyPair identityKey = KeyHelper.generateIdentityKeyPair();
List<PreKeyRecord> oneTimePreKeys = KeyHelper.generatePreKeys(100);
PreKeyRecord lastResortKey = KeyHelper.generateLastResortKey();
SignedPreKeyRecord signedPreKeyRecord = KeyHelper.generateSignedPreKey(identityKey, signedPreKeyId);
`````
The above are then stored locally so that they're available for load via the `AxolotlStore`.
## Registering
At install time, clients need to register with the TextSecure server.
`````
private final String URL = "https://my.textsecure.server.com";
private final TrustStore TRUST_STORE = new MyTrustStoreImpl();
private final String USERNAME = "+14151231234";
private final String PASSWORD = generateRandomPassword();
TextSecureAccountManager accountManager = new TextSecureAccountManager(URL, TRUST_STORE,
USERNAME, PASSWORD);
accountManager.requestSmsVerificationCode();
accountManager.verifyAccount(receivedSmsVerificationCode, generateRandomSignalingKey(),
false, generateRandomInstallId());
accountManager.setGcmId(Optional.of(GoogleCloudMessaging.getInstance(this).register(REGISTRATION_ID)));
accountManager.setPreKeys(identityKey.getPublic(), lastResortKey, signedPreKey, oneTimePreKeys);
`````
## Sending text messages
`````
TextSecureMessageSender messageSender = new TextSecureMessageSender(URL, TRUST_STORE, USERNAME, PASSWORD,
localRecipientId, new MyAxolotlStore(),
Optional.absent());
long recipientId = getRecipientIdFor("+14159998888");
TextSecureAddress destination = new TextSecureAddress(recipientId, "+14159998888", null);
TextSecureMessage message = new TextSecureMessage(System.currentTimeMillis(), "Hello, world!");
messageSender.sendMessage(destination, message);
`````
## Sending media messages
`````
TextSecureMessageSender messageSender = new TextSecureMessageSender(URL, TRUST_STORE, USERNAME, PASSWORD,
localRecipientId, new MyAxolotlStore(),
Optional.absent());
long recipientId = getRecipientIdFor("+14159998888");
TextSecureAddress destination = new TextSecureAddress(recipientId, "+14159998888", null);
File myAttachment = new File("/path/to/my.attachment");
FileInputStream attachmentStream = new FileInputStream(myAttachment);
TextSecureAttachment attachment = new TextSecureAttachmentStream(attachmentStream, "image/png", myAttachment.size());
TextSecureMessage message = new TextSecureMessage(System.currentTimeMillis(), attachment, "Hello, world!");
messageSender.sendMessage(destination, message);
`````
## Receiving messages
`````
TextSecureMessageReceiver messageReceiver = new TextSecureMessageReceiver(URL, TRUST_STORE, USERNAME, PASSWORD, mySignalingKey);
TextSecureMessagePipe messagePipe;
try {
messagePipe = messageReciever.createMessagePipe();
while (listeningForMessages) {
TextSecureEnvelope envelope = messagePipe.read(timeout, timeoutTimeUnit);
TextSecureCipher cipher = new TextSecureCipher(new MyAxolotlStore(),
getRecipientIdFor(envelope.getSource()),
envelope.getSourceDevice());
TextSecureMessage message = cipher.decrypt(envelope);
System.out.println("Received message: " + message.getBody().get());
}
} finally {
if (messagePipe != null)
messagePipe.close();
}
`````
