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§
- Channel
Derivation Parameters - The parameters required to derive a channel signer via
SignerProvider. - Delayed
Payment Output Descriptor - Information about a spendable output to a P2WSH script.
- HTLC
Descriptor - A descriptor used to sign for a commitment transaction’s HTLC output.
- InMemory
Signer - A simple implementation of
WriteableEcdsaChannelSignerthat 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.
- Keys
Manager - Simple implementation of
EntropySource,NodeSigner, andSignerProviderthat takes a 32-byte seed for use as a BIP 32 extended key and derives keys from that. - Phantom
Keys Manager - Similar to
KeysManager, but allows the node using this struct to receive phantom node payments. - Static
Payment Output Descriptor - Information about a spendable output to our “payment key”.
Enums§
- Recipient
- Specifies the recipient of an invoice.
- Spendable
Output Descriptor - Describes the necessary information to spend a spendable output.
Traits§
- Channel
Signer - A trait to handle Lightning channel key material without concretizing the channel type or the signature mechanism.
- Ecdsa
Channel Signer - A trait to sign Lightning channel transactions as described in BOLT 3.
- Entropy
Source - A trait that describes a source of entropy.
- Node
Signer - A trait that can handle cryptographic operations at the scope level of a node.
- Signer
Provider - A trait that can return signer instances for individual channels.
- Writeable
Ecdsa Channel Signer - A writeable signer.
