a) Better crypto (replaced SHA1/DH/RSA1024 with SHA3/ed25519/curve25519) Don't allow New Tor nodes to build circuits with obsolete Tor Nodes unless they support the newer encryption version 0.3.2.9 - 2018-01-09 Only use the old crypto to resolve old .Onion honeypots........... Only use SHA3/ed25519/curve25519 to build New 3 hop Circuits. This will provide better anon for hidden services which use the same transport system. **Trac**: **Username**: Anony
