Description

https://github.com/digitalbazaar/ezcap/blob/main/lib/ZcapClient.js#L49-L60

It is currently possible the initialize a ZcapClient supplying signer APIs that are associated with a key that has no private key material associated with it. When this happens, one later discovers when calling a client API such as delegate that the signer is not capable of performing a signing operation.

https://github.com/digitalbazaar/ed25519-verification-key-2020/blob/main/lib/Ed25519VerificationKey2020.js#L405

If possible, it would be good to validate that the signers passed to the ZcapClient constructor are actually valid.

Research direction

Start at the ZcapClient constructor in lib/ZcapClient.js#L49-L60 and inspect the signer behavior referenced in Ed25519VerificationKey2020.js#L405. Determine how to recognize signer instances without private key material and add coverage for constructor validation; done means invalid signers fail during construction rather than later during delegate or another signing operation.
