Examples with GroupCipher org.whispersystems.libsignal.groups.GroupCipher used on opensource projects

Example 1 with GroupCipher

use of org.whispersystems.libsignal.groups.GroupCipher in project Signal-Android by WhisperSystems.

the class SignalServiceCipher method encryptForGroup.

public byte[] encryptForGroup(DistributionId distributionId, List<SignalProtocolAddress> destinations, SenderCertificate senderCertificate, byte[] unpaddedMessage, ContentHint contentHint, byte[] groupId) throws NoSessionException, UntrustedIdentityException, InvalidKeyException, InvalidRegistrationIdException {
    PushTransportDetails transport = new PushTransportDetails();
    SignalProtocolAddress localProtocolAddress = new SignalProtocolAddress(localAddress.getIdentifier(), localDeviceId);
    SignalGroupCipher groupCipher = new SignalGroupCipher(sessionLock, new GroupCipher(signalProtocolStore, localProtocolAddress));
    SignalSealedSessionCipher sessionCipher = new SignalSealedSessionCipher(sessionLock, new SealedSessionCipher(signalProtocolStore, localAddress.getServiceId().uuid(), localAddress.getNumber().orNull(), localDeviceId));
    CiphertextMessage message = groupCipher.encrypt(distributionId.asUuid(), transport.getPaddedMessageBody(unpaddedMessage));
    UnidentifiedSenderMessageContent messageContent = new UnidentifiedSenderMessageContent(message, senderCertificate, contentHint.getType(), Optional.of(groupId));
    return sessionCipher.multiRecipientEncrypt(destinations, messageContent);
}

Example 2 with GroupCipher
