I got tired of the "email it to yourself" dance every time I needed to move a file to my phone. Built a small Go CLI that spins up a local HTTP server and generates a QR code — scan it and download/upload directly. The tool features: Two-way transfers (send and receive in the same session) Directory browsing mode Optional AES-256-GCM encryption with the key embedded in the QR code's URL fragment (never hits the wire) https://github.com/axiom0x0/bifrost The encryption bit was horrible to figure out thanks to Safari; Web Crypto API doesn't work over plain HTTP, so it ships a pure JS AES-GCM fallback. If folks are interested, or want more of the background + some Safari errata, I wrote up the full debugging saga here https://axiom0x0.sh/tools/bifrost/.   submitted by   /u/CableFPV [link]   [comments]
