Module diem_crypto::traits

This module provides a generic set of traits for dealing with cryptographic primitives.

For examples on how to use these traits, see the implementations of the ed25519 modules.

Enums

• CryptoMaterialError
  An error type for key and signature validation issues, see ValidCryptoMaterial.

Traits

• Genesis
  A type family with a by-convention notion of genesis private key.
• Length
  The serialized length of the data that enables macro derived serialization and deserialization.
• PrivateKey
  A type family for key material that should remain secret and has an associated type of the PublicKey family.
• PublicKey
  A type for key material that can be publicly shared, and in asymmetric fashion, can be obtained from a PrivateKey reference. This convertibility requirement ensures the existence of a deterministic, canonical public key construction from a private key.
• Signature
  A type family for signature material that knows which public key type is needed to verify it, and given such a public key, knows how to verify.
• SigningKey
  A type family of valid keys that know how to sign.
• Uniform
  A type family for schemes which know how to generate key material from a cryptographically-secure CryptoRng.
• VRFPrivateKey
  Private key for VRF
• VRFProof
  The proof of VRF
• VRFPublicKey
  Public key for VRF
• ValidCryptoMaterial
  Key or more generally crypto material with a notion of byte validation.
• ValidCryptoMaterialStringExt
  An extension to to/from Strings for ValidCryptoMaterial.
• VerifiableDelayFunction
  The trait for VDF.
• VerifyingKey
  A type family of public keys that are used for signing.

Functions

• vrf_number_with_nonce
  Hash the vrf output and a nonce within the proposer’s voting power to compute a hash value as its priority. This is used in both choosing leaders in a round and electing committees in a term.
