/*
|
|
|
|
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.
