Module sign

Expand description

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.

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.
StaticPaymentOutputDescriptor: Information about a spendable output to our “payment key”.

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

ChannelSigner: A trait to handle Lightning channel key material without concretizing the channel type or the signature mechanism.
EcdsaChannelSigner: A trait to sign Lightning channel transactions as described in BOLT 3.
EntropySource: A trait that describes a source of entropy.
NodeSigner: A trait that can handle cryptographic operations at the scope level of a node.
SignerProvider: A trait that can return signer instances for individual channels.
WriteableEcdsaChannelSigner: A writeable signer.
