Crate hashes

Rust hashes library.

This is a simple, no-dependency library which implements the hash functions needed by Bitcoin. These are SHA256, SHA256d, and RIPEMD160. As an ancillary thing, it exposes hexadecimal serialization and deserialization, since these are needed to display hashes anway.

Modules

cmp

Useful comparison functions.

error

Crate error type.

hash160

HASH160 (SHA256 then RIPEMD160) implementation.

hex

Hex encoding and decoding.

hmac

Hash-based Message Authentication Code (HMAC).

ripemd160

RIPEMD160 implementation.

serde_macros

Macros for serde trait implementations, and supporting code.

sha1

SHA1 implementation.

sha256

SHA256 implementation.

sha512

SHA512 implementation.

sha256d

SHA256d implementation (double SHA256).

sha256t

SHA256t implementation (tagged SHA256).

siphash24

SipHash 2-4 implementation.

Macros

borrow_slice_impl

Adds slicing traits implementations to a given type $ty

hash_newtype

Creates a new newtype around a Hash type.

hex_fmt_impl

Adds hexadecimal formatting implementation of a trait $imp to a given type $ty.

serde_impl

Implements Serialize and Deserialize for a type $t which represents a newtype over a byte-slice over length $len.

sha256t_hash_newtype

Macro used to define a newtype tagged hash. It creates two public types:

Structs

Hmac

A hash computed from a RFC 2104 HMAC. Parameterized by the underlying hash function.

HmacEngine

Pair of underyling hash engines, used for the inner and outer hash of HMAC.

Enums

Error

Crate error type.

Traits

Hash

Trait which applies to hashes of all types.

HashEngine

A hashing engine which bytes can be serialized into.
