TLS and ZeroMQ
September 16, 2012
It’s pretty straightforward to use synchronous encryption over ZeroMQ - just a case of encrypting and decrypting at each end with some previously shared key. Asynchronous encryption is a bit more interesting, as it allows signing for message integrity and authenticity, as well as data hiding. There have been some good examples of crypto over Pub/Sub (notably Salt), but not a lot of examples of direct messaging.
