o Major features (Ed25519 identity keys: #12498, Prop220):
|
|
- All relays now maintain a stronger identity key, using the
|
|
Ed25519 elliptic curve signature format. This master key is
|
|
designed so that it can be kept offline. Relays also generate
|
|
an online signing key, and a set of other Ed25519 keys and certificates.
|
|
These are all automatically regenerated and rotated as needed.
|
|
- Directory authorities track which Ed25519 identity keys have been
|
|
used with which RSA1024 identity keys, and do not allow them to vary
|
|
freely.
|
|
- Directory authorities now vote on Ed25519 identity keys along with
|
|
RSA1024 keys.
|
|
- Microdescriptors now include ed25519 identity keys.
|
|
|
|
o Major features (onion key cross-certification):
|
|
- Relay descriptors now include signatures of the identity keys using
|
|
the TAP and ntor onion keys. This allows relays to prove ownership of
|
|
their own onion keys. Because of this change, microdescriptors no longer
|
|
need to include RSA identity keys. Implements proposal 228;
|
|
closes ticket 12499.
|
|
|
|
o Code simplification and refactoring:
|
|
- The link authentication code has been refactored for better testability
|
|
and reliability. It now uses code generated with the "trunnel"
|
|
binary encoding generator, to reduce the risk of bugs due to
|
|
programmer error. Done as part of ticket 12498.
|
|
|
|
o Testing:
|
|
- The link authentication protocol code now has extensive tests.
|
|
- The relay descriptor signature testing code now has extensive tests.
