Module primitives

Implements low-level cryptographic primitives, such as SimpleStreamCipher, SimpleDigest and SimpleMac.

Structs

EthDigest

Computation wrapper for a digest that’s compatible with Ethereum digests. Use new, update and finalize triplet to produce hash of arbitrary data. Currently this instance is using Keccak256.

SimpleDigest

Simple digest computation wrapper. Use new, update and finalize triplet to produce hash of arbitrary data. Currently this instance is using Blake2s256.

SimpleMac

Simple Message Authentication Code (MAC) computation wrapper Use new, update and finalize triplet to produce MAC of arbitrary data. Currently instantiated using Blake2s256 MAC.

SimpleStreamCipher

Simple stream cipher wrapper Use new and apply (or apply_copy) to XOR the keystream on the plaintext or ciphertext. Currently this instance is using ChaCha20.

Traits

DigestLike

Generalization of digest-like operation (MAC, Digest,…) Defines the update and finalize operations to produce digest value of arbitrary data.

Type Aliases

SecretKey

Represents a secret key of fixed length. The value is auto-zeroized on drop.
