/*

Package privval provides different implementations of the types.PrivValidator.

FilePV

FilePV is the simplest implementation and developer default.
It uses one file for the private key and another to store state.

SignerListenerEndpoint

SignerListenerEndpoint establishes a connection to an external process,
like a Key Management Server (KMS), using a socket.
SignerListenerEndpoint listens for the external KMS process to dial in.
SignerListenerEndpoint takes a listener, which determines the type of connection
(ie. encrypted over tcp, or unencrypted over unix).

SignerDialerEndpoint

SignerDialerEndpoint is a simple wrapper around a net.Conn. It's used by both IPCVal and TCPVal.

SignerClient

SignerClient handles remote validator connections that provide signing services.
In production, it's recommended to wrap it with RetrySignerClient to avoid
termination in case of temporary errors.
