Module bitcoin::key

Bitcoin keys.

This module provides keys used in Bitcoin that can be roundtrip (de)serialized.

Re-exports

Modules

• constants
  Constants related to the API and the underlying curve.

Structs

  Invalid address version in decoded base58 data.
• InvalidBase58PayloadLengthError
  Decoded base58 data was an invalid length.
• Keypair
  Opaque data structure that holds a keypair consisting of a secret and a public key.
• PrivateKey
  A Bitcoin ECDSA private key
• PubkeyHash
  A hash of a public key.
• PublicKey
  A Bitcoin ECDSA public key
• Secp256k1
  The secp256k1 engine, used to execute all signature operations.
