(Disclaimer: not related to the referenced narrowlink code, but the sentiment of the parent post) I which stuff like libsodium would be both more widely available and more widely used. And with "stuff" I don't mean the internal core primitives but the slightly more higher level helper which often try (in the limits of C) limit miss use and have reasonable good documentation. E.g. crypto_secretstream_xchacha20poly1305* from https://doc.libsodium.org/secret-key_cryptography https://doc.libsodium.org/secret-key_cryptography /secretstream Because while by now most people have understood that inventing/putting together their own low level crypto primitives is a bad idea, people using existing low level primitives to invent their own "mid level" primitives still happen more often then healthy in the industry.
