Crate tor_key_forge

tor-keys

Crate for the cryptographic keys in the Tor landscape.

Overview

The tor-keys crate manages all high level wrappers around lower-level cryptographic primitives found in tor-llcrypto.

More specifically, wrappers are used in order to bring semantic on top of lower-level crypto keys which helps avoid mixing keys in the code base.

For example, defining a long term identity relay signing keypair around a lower level ed25519 keypair makes it so that we can’t use that key to be used for another purpose.

This crate is part of Arti, a project to implement Tor in Rust.

Macros

define_curve25519_keypair

Create a curve25519 keypair wrapper given a visibility and a struct name.

define_ed25519_keypair

Create an ed25519 keypair wrapper given a visibility and a struct name.

derive_deftly_template_Curve25519Keypair

Implement set of helper functions around a type wrapping an ed25519::Keypair.

derive_deftly_template_Ed25519Keypair

Implement set of helper functions around a type wrapping an ed25519::Keypair.

Structs

Ed25519Cert

Structure for an Ed25519-signed certificate as described in Tor’s cert-spec.txt.

EncodedEd25519Cert

An encoded ed25519 certificate, created using [Ed25519CertConstructor::encode_and_sign].

KeyUnknownCert

A parsed Ed25519 certificate. Maybe it includes its signing key; maybe it doesn’t.

ParsedEd25519Cert

A parsed EncodedEd25519Cert.

SshKeyData

A public key or a keypair.

ValidatedEd25519Cert

A well-signed and timely EncodedEd25519Cert.

Enums

CertData

A key certificate.

CertType

A type of certificate stored in the keystore.

Error

An Error type for this crate.

InvalidCertError

The error type returned by ToEncodableCert::validate.

KeyType

A type of key stored in the key store.

KeystoreItem

A public key, keypair, or key certificate.

KeystoreItemType

A type of item stored in a keystore.

SshKeyAlgorithm

SSH key algorithms.

Traits

EncodableItem

A key that can be serialized to, and deserialized from.

ItemType

A trait for getting the type of an item.

Keygen

A trait for generating fresh keys.

KeygenRng

A random number generator for generating EncodableItems.

ToEncodableCert

A trait representing an encodable certificate.

ToEncodableKey

A key that can be converted to an EncodableItem.

Type Aliases

ErasedKey

A type-erased key. Used by the tor-keymgr.

Result

A Result type for this crate.
