But not legally. Meaning you won't be able to buy anything on the open market, and it will be unlawful to possess anything. There are laws in place that make it a crime to crack an encrypted transmission. Encrypted signals are intended to remain private, whereas trunked signals and digital signals were intended simply as improvements to communications, not attempts to prevent outsiders from listening. There was no law preventing scanning technology from catching up.Let me further say that if it becomes the norm, SOMEONE will figure out how to decode it eventually.
How to decrypt is in the open standard, so there's nothing really to figure out. It's just a matter of trying out the huge number (more than trillions, right?) of different possible encryption codes, so have at it! Sure, computing power will eventually advance to the point that a brute force / trial & error solution to current schemes is feasible for average hobbyists, but the users will be several generations past this encryption scheme by then.SOMEONE will figure out how to decode it eventually.
