A transceiver that can encrypt is not illegal to use. But you cannot use encryption on any amateur radio band except for certain functions. Notably command-and-control communications for satellite use. That function allows the use of encryption for obvious reasons.

Basic Two-Way Radio Etiquette Rules: When using a two-way radio you cannot speak and listen at the same time, as you can with a phone. Don't interrupt if you hear other people talking. Wait until their conversation is finished. unless it is an emergency.

Perhaps the most important tip to know about two-way radio communication is that certain words and phrases should be used when greeting, speaking to, and saying goodbye to another party. That's because some words used in everyday speech don't always transmit clearly over two-way radio waves.

The encryption key is used by the transmit and receive radios to enable the voice signal to be coded and decoded for both radios. Therefore, all radios communicating must have matching encryption keys to receive transmissions. There are several different methods for encrypting voice signals.

Secure Radio Communication Systems Adopt a tested standard of key generation and distribution parameters that will enhance interoperability between known mobile radio devices. Develop and effective key management structure. Develop and stick to a storage location number plan that works for all parties.

Essentially, military grade encryption works by scrambling data into a mathematical algorithm and then encrypting it with a key. The key is generated using an advanced form of cryptography called public-key cryptography. This cryptography utilizes two different keys to secure the data.

The short answer is that you can encrypt your conversation so that almost no one else can tune in. However, for most purposes in the USA, it is likely illegal. FRS, GMRS, CB, and Amateur Radio all require that conversations are done without encryption. Business and public safety licenses can encrypt if they wish.
