Overview

Package signer keeps the CA key away from the gate (decision D3): the signer process alone reads the key and issues leaf certificates over a Unix socket to the uids it allows; the gate asks it for each host it decrypts.

Functions

func Listen 

func Listen(path string) (net.Listener, error)

Listen opens the socket at path (mode 0660; the directory is the caller's).

Types

type Client 

type Client struct {
	Path string
	// CACert is the CA certificate the leaves must chain to.
	CACert *x509.Certificate
	// Dial replaces the socket dial (tests).
	Dial func(ctx context.Context) (net.Conn, error)
	// contains filtered or unexported fields
}

Client asks a signer for leaves and caches them; it implements the gate's CertSource. It checks each leaf against the CA certificate.

func (*Client) Certificate 

func (c *Client) Certificate(ctx context.Context, host string) (*tls.Certificate, error)

Certificate implements gate.CertSource.

type Server 

type Server struct {
	CA *ca.CA
	// AllowUIDs may ask; empty allows the signer's own uid only.
	AllowUIDs []int
	// PeerUID replaces the kernel's peer check (tests).
	PeerUID func(net.Conn) (int, error)
	Log     io.Writer
}

Server issues leaves to allowed peers.

func (*Server) Serve 

func (s *Server) Serve(ln net.Listener) error

Serve answers on ln until it closes.
