Module lightning::sign

Provides keys to LDK and defines some useful objects describing spendable on-chain outputs.

The provided output descriptors follow a custom LDK data format and are currently not fully compatible with Bitcoin Core output descriptors.

Modules

• ecdsa
  Defines ECDSA-specific signer types.

Structs

• ChannelDerivationParameters
  The parameters required to derive a channel signer via SignerProvider.
• DelayedPaymentOutputDescriptor
  Information about a spendable output to a P2WSH script.
• HTLCDescriptor
  A descriptor used to sign for a commitment transaction’s HTLC output.
• InMemorySigner
  A simple implementation of WriteableEcdsaChannelSigner that just keeps the private keys in memory.
• KeyMaterial
  Used as initial key material, to be expanded into multiple secret keys (but not to be used directly). This is used within LDK to encrypt/decrypt inbound payment data.
• KeysManager
  Simple implementation of EntropySource, NodeSigner, and SignerProvider that takes a 32-byte seed for use as a BIP 32 extended key and derives keys from that.
• PhantomKeysManager
  Similar to KeysManager, but allows the node using this struct to receive phantom node payments.
• RandomBytes
  An implementation of EntropySource using ChaCha20.
• StaticPaymentOutputDescriptor
  Information about a spendable output to our “payment key”.

Enums

• Recipient
  Specifies the recipient of an invoice.
• SpendableOutputDescriptor
  Describes the necessary information to spend a spendable output.

Traits

• ChangeDestinationSource
  A helper trait that describes an on-chain wallet capable of returning a (change) destination script.
• ChannelSigner
  A trait to handle Lightning channel key material without concretizing the channel type or the signature mechanism.
• EntropySource
  A trait that describes a source of entropy.
• NodeSigner
  A trait that can handle cryptographic operations at the scope level of a node.
• OutputSpender
  A trait that describes a wallet capable of creating a spending Transaction from a set of SpendableOutputDescriptors.
• SignerProvider
  A trait that can return signer instances for individual channels.
