Booth uses 32-bit time_t

[jfriesse]

32-bit time_t means booth stops working by 2k38. This must be somehow solved, sadly it is pretty hard because of binary nature of protocol and backwards compatibility.

One of the solution might be to add better cryptography (not just signing of messages but also encryption).
