I'm not a cryptographer and when I look at other applications, almost always AES-GCM or ChaCha20-Poly1305 is used for authenticated encryption.
So, I wonder why that is. Are the new CAESAR algorithms too new, or are there not enough implementations in the different programming languages? Other reasons?
As a programmer: When I design a new system today, should I consider the new CAESAR algorithms? Are there technical advantages/disadvantages?
Also, I heard of the Lightweight Cryptography project organized by NIST. Is not this competition redundant given the category 1: Lightweight applications (resource constrained environments) in the CAESAR competition?
