__DataDirectory__**/keys/***::
Only used by servers. Holds identity keys and onion keys.
__DataDirectory__**/keys/authority_identity_key**::
A directory authority's master identity key, used to authenticate its
signing key. Tor doesn't use this while it's running. The tor-gencert
program uses this. If you're running an authority, you should keep this
key offline, and not actually put it here.
__DataDirectory__**/keys/authority_certificate**::
A directory authority's certificate, which authenticates the authority's
current vote- and consensus-signing key using its master identity key.
Only directory authorities use this file.
__DataDirectory__**/keys/authority_signing_key**::
A directory authority's signing key, used to sign votes and consensuses.
Only directory authorities use this file. Corresponds to the
**authority_certificate** cert.
__DataDirectory__**/keys/legacy_certificate**::
As authority_certificate: used only when V3AuthUseLegacyKey is set.
See documentation for V3AuthUseLegacyKey.
__DataDirectory__**/keys/legacy_signing_key**::
As authority_signing_key: used only when V3AuthUseLegacyKey is set.
See documentation for V3AuthUseLegacyKey.
__DataDirectory__**/keys/secret_id_key**::
A relay's RSA1024 permanent identity key, including private and public
components. Used to sign router descriptors, and to sign other keys.
__DataDirectory__**/keys/ed25519_master_id_public_key**::
The public part of a relay's Ed25519 permanent identity key.
__DataDirectory__**/keys/ed25519_master_id_secret_key**::
The private part of a relay's Ed25519 permanent identity key. This key
is used to sign the medium-term ed25519 signing key. This file can be
kept offline, or kept encrypted. If so, Tor will not be able to generate
new signing keys itself; you'll need to use tor --keygen yourself to do
so.
__DataDirectory__**/keys/ed25519_signing_secret_key**::
The private and public components of a relay's medium-term Ed25519 signing
key. This key is authenticated by the Ed25519 master key, in turn
authenticates other keys (and router descriptors).
__DataDirectory__**/keys/ed25519_signing_cert**::
The certificate which authenticates "ed25519_signing_secret_key" as
having been signed by the Ed25519 master key.
__DataDirectory__**/keys/secret_onion_key**::
A relay's RSA1024 short-term onion key. Used to decrypt old-style ("TAP")
circuit extension requests.
__DataDirectory__**/keys/secret_onion_key_ntor**::
A relay's Curve25519 short-term onion key. Used to handle modern ("ntor")
circuit extension requests.
__DataDirectory__**/fingerprint**::
Only used by servers. Holds the fingerprint of the server's identity key.
