But, that doesn't mean he doesn't know about computer message security. His choice? Signal. Encrypted from end to end. The ability to cause messages to disappear after they are sent. No ads, emojis, or other fluff. Just secure messaging for free. A lawyer who needs secure communication of client sensitive data should be using it. The major problem with it is that both parties must be using it; but, a conversation that needs to be secure will likely be with someone who shares the same need for security.
