* Introduces `author_hasKey` and `author_hasSessionKeys` rpc endpoints Both endpoints can be used to check if a key is present in the keystore. - `hasKey` works on with an individual public key and key type. It checks if a private key for the given combination exists in the keystore. - `hasSessionKeys` works with the full encoded session key blob stored on-chain in `nextKeys`. This requires that the given blob can be decoded by the runtime. It will return `true`, iff all public keys of the session key exist in the storage. Fixes: https://github.com/paritytech/substrate/issues/4696 * Update client/rpc-api/src/author/error.rs Co-Authored-By: Nikolay Volf <nikvolf@gmail.com> * Indentation Co-authored-by: Nikolay Volf <nikvolf@gmail.com>
