LND Macaroon Decoder

This NPM package helps decoding macaroons for LND.

Built with help of guggero/cryptography-toolkit

getMacaroonOperations takes in an LND macaroon in hex format and returns an array of entities and actions.

const permissions = getMacaroonOperations(macaroonHex);

for (const { entity, actions } of permissions) {
  console.log({ entity, actions });
}

// { entity: 'address', actions: [ 'read' ] }
// { entity: 'info', actions: [ 'read' ] }
// { entity: 'macaroon', actions: [ 'write' ] }
// {
//   entity: 'uri',
//   actions: [
//     '/lnrpc.Lightning/AddInvoice',
//     '/peersrpc.Peers/UpdateNodeAnnouncement'
//   ]
// }

getFlatPermissionList and verifyMacaroonPermissions are helper functions to check the macaroon permissions.
