/*

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.

SignerValidatorEndpoint

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

SignerServiceEndpoint

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