Rsynccrypt allegedly uses AES encryption in CBC mode where the IV is reused for the next block after some runs of bytes (defined by the trigger function).
Does that weaken the encryption somehow? If so, how?
Edit: The whole scheme with RSA encryption for each file is something I haven’t seen anywhere else. Possibly to prevent tampering? This makes replay attacks still feasible, doesn’t it?
Yet, is the altered AES-CBC secure? With some modifications, It could be still viable.
