<p>despite how janky-looking it is, their cryptographic scheme actually includes _some_ measure of replay protection (there's a sequence number in the encrypted blob)</p><p>it's still malleable, of course; you could conceivably flip bits in the ciphertext in the known positions to advance it</p>
<p>ciphertexts only do this when they're very distressed!!</p><p>(although i know the first bytes of plaintext, AES is resistant to CPA, so unfortunately this doesn't quite break it completely)</p>
