Module fog_crypto::hash

Cryptographic hashing.

This module lets you create a cryptographic hash from a byte stream. Cryptographic hashes can be used to uniquely identify a data sequence. They can be passed to an IdentityKey to be signed.

Example

// Create a new hash from raw bytes
let hash = Hash::new(b"I am the entire data sequence");
println!("Hash(Base58): {}", hash);

// Create a hash by feeding in bytes repeatedly
let mut hash_state = HashState::new();
hash_state.update(b"I am the first part of a data sequence");
hash_state.update(b"And I am their sibling, the second part of a data sequence");
let hash = hash_state.finalize();
println!("Hash(Base58): {}", hash);

Structs

• Hash
  Crytographically secure hash of data.
• HashState
  A hasher that can incrementally take in data and produce a hash at any time.

Constants

• DEFAULT_HASH_VERSION
  Default Hash algorithm version.
• MAX_HASH_LEN
  Maximum size that a hash could be. This may change when versions increment.
• MAX_HASH_VERSION
  Maximum accepted Hash algorithm version.
• MIN_HASH_VERSION
  Minimum accepted Hash algorithm version.
