The "verifier id" is a tagged hash of the encrypted file to be uploaded.
It is used as an index to the [StorageServer](StorageServer) service on each peer. Each [StorageServer](StorageServer) holds zero or more shares for each file in objects called "buckets": the collection of these buckets is indexed by verifierid.
The same plaintext file can be encrypted in multiple ways (by changing the encryption key): each different resulting crypttext will have a different verifierid. As a result there is a one-to-many mapping from [FileId](FileId) to [VerifierId](VerifierId).
