Encyfr – post-quantum encryption for all

I wanted proper post-quantum crypto tools on my phone, so I built encyfr. There’s no telemetry, no accounts, and everything runs locally. It supports key generation/management, file encryption, and signing with the NIST pqc choices (Kyber, Dilithium, AES256) as well as password modes. Normally I haven't bothered circulating my work, but several recent concerns about phone compromise can be resolved with proper encryption utilities like these (e.g. any agency with a GrayKey). I’m curious if others here find this kind of thing useful/interesting, and what features would make it genuinely useful to you. Not available in France.
