Method Detail

• encrypt

   CiphertextMessage encrypt(Array<byte> paddedMessage)

  Encrypt a message.

  Parameters:

  paddedMessage - The plaintext message bytes, optionally padded to a constant multiple.

  Returns:

  A ciphertext message encrypted to the recipient+device tuple.

• encrypt

   CiphertextMessage encrypt(Array<byte> paddedMessage, Instant now)

  Encrypt a message.

  You should only use this overload if you need to test session expiration explicitly.

  Parameters:

  paddedMessage - The plaintext message bytes, optionally padded to a constant multiple.

  Returns:

  A ciphertext message encrypted to the recipient+device tuple.

• decrypt

   Array<byte> decrypt(PreKeySignalMessage ciphertext, UsePqRatchet usePqRatchet)

  Decrypt a message.

  Parameters:

  ciphertext - The PreKeySignalMessage to decrypt.

  Returns:

  The plaintext.

• decrypt

   Array<byte> decrypt(SignalMessage ciphertext)

  Decrypt a message.

  Parameters:

  ciphertext - The SignalMessage to decrypt.

  Returns:

  The plaintext.

• getRemoteRegistrationId

   int getRemoteRegistrationId()

• getSessionVersion
