Age is new to me, I immediately find there's a Go (age) and Rust (rage) implementation - which one is the encryption community at large favoring more? (stability, code quality, etc.)
I'm not involved with either, but I've looked at both for other projects[1]. The Rust implementation's CLI mirrors that of the reference (Go) implementation, and I haven't had stability issues with either. I found the Rust implementation's source code readable and decently documented.
