Obsolete Tor Core Encryption, Only use SHA3/ed25519/curve25519 for building Circuits
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.
