After spending some time with the #minipgp6 encryption/decryption code over the last few days, I decided to finally have a look at the "age" tool (which I had thus far never tried).
I wrote up a comparison between the SOP CLI standard for file encryption, and the age tool:

The text includes some benchmarks to compare msop and age.

File encryption with SOP/OpenPGP (and age)
This article explores file encryption with Stateless OpenPGP (SOP) tools, and contrasts this use of SOP with the age tool. SOP is a CLI standard for (vendor-agnostic) OpenPGP tools. There are numerous independent implementations of SOP, based on a variety of OpenPGP implementations in different languages. The msop implementation of SOP # In this article, we’ll use the msop implementation of SOP. It is based on the very small minipgp6 Rust library. minipgp6 supports only a narrow modern set of algorithms, with v6 keys as specified in RFC 9580 and comes with native support for PQC.
