Does this mean TS is not FIPS 140-3 now?

It never was FIPS-approved and likely will never be. The wireguard protocol used by Tailscale uses ChaCha20 for encryption which is not FIPS approved.

  • Interesting. What is the FIPS version of wireguard?

    • There are some forks that are not compatible with regular wireguard, for example from wolfssl. Or just classic mTLS.

      IPsec or TLS-based overlays which use AES encryption and NIST-approved ECC curves or (gasp) RSA for key exchange and authentication. They generally suck in comparison with wireguard, which is a clean-sheet modern cryptographic protocol.
