Module tor_llcrypto::pk::ed25519

Re-exporting Ed25519 implementations, and related utilities.

Here we re-export types from [ed25519_dalek] that implement the Ed25519 signature algorithm. (TODO: Eventually, this module should probably be replaced with a wrapper that uses the ed25519 trait and the Signature trait.)

We additionally provide an Ed25519Identity type to represent the unvalidated Ed25519 “identity keys” that we use throughout the Tor protocol to uniquely identify a relay.

Structs

• Ed25519Identity
  An unchecked, unvalidated Ed25519 key.
• ExpandedKeypair
  A variant of Keypair containing an [ExpandedSecretKey].
• Keypair
  ed25519 signing key which can be used to produce signatures.
• PublicKey
  An ed25519 public key.
• Signature
  Ed25519 signature.
• ValidatableEd25519Signature
  An ed25519 signature, plus the document that it signs and its public key.

Constants

• ED25519_ID_LEN
  The length of an ED25519 identity, in bytes.
• ED25519_SIGNATURE_LEN
  The length of an ED25519 signature, in bytes.

Traits

• Ed25519PublicKey
  An object that has an Ed25519 PublicKey.
• Signer
  Sign the provided message bytestring using Self (e.g. a cryptographic key or connection to an HSM), returning a digital signature.
• Verifier
  Verify the provided message bytestring using Self (e.g. a public key)

Functions

• validate_batch
  Perform a batch verification operation on the provided signatures
