Overview

Package ocsp exposes OCSP signing functionality, much like the signer package does for certificate signing. It also provies a basic OCSP responder stack for serving pre-signed OCSP responses.

Types

type InMemorySource

type InMemorySource map[string][]byte

An InMemorySource is a map from serialNumber -> der(response)

func (InMemorySource) Response

func (src InMemorySource) Response(request *ocsp.Request) (response []byte, present bool)

Response looks up an OCSP response to provide for a given request. InMemorySource looks up a response purely based on serial number, without regard to what issuer the request is asking for.

type Responder

type Responder struct {
	Source Source
}

A Responder object provides the HTTP logic to expose a Source of OCSP responses.

func (Responder) ServeHTTP

func (rs Responder) ServeHTTP(response http.ResponseWriter, request *http.Request)

A Responder can process both GET and POST requests. The mapping from an OCSP request to an OCSP response is done by the Source; the Responder simply decodes the request, and passes back whatever response is provided by the source.

type SignRequest

type SignRequest struct {
	Certificate *x509.Certificate
	Status      string
	Reason      int
	RevokedAt   time.Time
}

SignRequest represents the desired contents of a specific OCSP response.

type Signer

type Signer interface {
	Sign(req SignRequest) ([]byte, error)
}

Signer represents a general signer of OCSP responses. It is responsible for populating all fields in the OCSP response that are not reflected in the SignRequest.

func NewSigner

func NewSigner(issuer, responder *x509.Certificate, key crypto.Signer, interval time.Duration) (Signer, error)

NewSigner simply constructs a new StandardSigner object from the inputs, taking the interval in seconds

func NewSignerFromFile

func NewSignerFromFile(issuerFile, responderFile, keyFile string, interval time.Duration) (Signer, error)

NewSignerFromFile reads the issuer cert, the responder cert and the responder key from PEM files, and takes an interval in seconds

type Source

type Source interface {
	Response(*ocsp.Request) ([]byte, bool)
}

Source represents the logical source of OCSP responses, i.e., the logic that actually chooses a response based on a request. In order to create an actual responder, wrap one of these in a Responder object and pass it to http.Handle.

func NewSourceFromFile

func NewSourceFromFile(responseFile string) (Source, error)

NewSourceFromFile reads the named file into an InMemorySource. The file read by this function must contain whitespace-separated OCSP responses. Each OCSP response must be in base64-encoded DER form (i.e., PEM without headers or whitespace). Invalid responses are ignored. This function pulls the entire file into an InMemorySource.

type StandardSigner

type StandardSigner struct {
	// contains filtered or unexported fields
}

StandardSigner is the default concrete type of OCSP signer. It represents a single responder (represented by a key and certificate) speaking for a single issuer (certificate). It is assumed that OCSP responses are issued at a regular interval, which is used to compute the nextUpdate value based on the current time.

func (StandardSigner) Sign

func (s StandardSigner) Sign(req SignRequest) ([]byte, error)

Sign is used with an OCSP signer to request the issuance of an OCSP response.
