Functions

func HTTPGatewayComposeService 

func HTTPGatewayComposeService(files HTTPGatewayFiles, spec HTTPGatewaySpec) string

func LoopbackHTTPSURL 

func LoopbackHTTPSURL(port int) (string, error)

func NewHTTPClient 

func NewHTTPClient(material TLSMaterial, requireClient bool) (*http.Client, error)

func NewHTTPClientForPolicy 

func NewHTTPClientForPolicy(material TLSMaterial, policy Policy) (*http.Client, error)

func NewHTTPClientWithBasicAuth added in v0.4.17 

func NewHTTPClientWithBasicAuth(material TLSMaterial, username, password string) (*http.Client, error)

func RetireTLSOverlap added in v0.4.21 

func RetireTLSOverlap(ctx context.Context, issuer Issuer, policy Policy, dir string) error

RetireTLSOverlap removes a previous CA only after the provider has verified the newly issued server/client leaves through its stable service endpoint. It is idempotent so a verified retirement can be retried safely.

func TCPGatewayComposeService 

func TCPGatewayComposeService(files TCPGatewayFiles, spec TCPGatewaySpec) string

func ValidateSignedCSR added in v0.4.23 

func ValidateSignedCSR(request CSRSigningRequest, issued IssuedCertificate, trust TrustBundle, now time.Time) error

ValidateSignedCSR verifies public issuance against the authoritative trust, rather than trusting a CA supplied alongside an arbitrary signed leaf.

func VerifyBrowserRoute added in v0.4.18 

func VerifyBrowserRoute(ctx context.Context, client *http.Client, rawURL string) error

VerifyBrowserRoute validates bounded same-authority redirects while preserving route-level reachability semantics for surfaces that intentionally answer with authentication challenges.

func VerifyBrowserRouteWithAllowedAuthorities added in v0.4.18 

func VerifyBrowserRouteWithAllowedAuthorities(ctx context.Context, client *http.Client, rawURL string, allowedURLs ...string) error

func VerifyBrowserSurface added in v0.4.18 

func VerifyBrowserSurface(ctx context.Context, client *http.Client, rawURL string) error

VerifyBrowserSurface validates a user-facing HTTPS URL the way a browser would reach it, while keeping redirect traversal bounded to the same effective authority. A non-default port therefore cannot silently collapse to HTTPS/443 during a redirect.

func VerifyBrowserSurfaceWithAllowedAuthorities added in v0.4.18 

func VerifyBrowserSurfaceWithAllowedAuthorities(ctx context.Context, client *http.Client, rawURL string, allowedURLs ...string) error

VerifyBrowserSurfaceWithAllowedAuthorities permits only the canonical URL plus explicitly listed HTTPS authorities. It is intended for products such as Keycloak where an admin alias may redirect to the canonical identity host.

func WaitHTTPS 

func WaitHTTPS(ctx context.Context, client *http.Client, endpoint, path string) error

Types

type AuthenticationMode 

type AuthenticationMode string
const (
	AuthenticationNone     AuthenticationMode = "none"
	AuthenticationNative   AuthenticationMode = "native"
	AuthenticationMTLS     AuthenticationMode = "mtls"
	AuthenticationToken    AuthenticationMode = "token"

	AuthenticationOAuth2   AuthenticationMode = "oauth2"
	AuthenticationExternal AuthenticationMode = "external"
)

type CSRIssuer added in v0.4.23 

type CSRIssuer interface {
	Issuer
	SignCSR(context.Context, CSRSigningRequest) (IssuedCertificate, error)
}

CSRIssuer signs a client-owned key through the existing protected authority. It must never generate or return a client private key.

type CSRSigningRequest added in v0.4.23 

type CSRSigningRequest struct {
	CSRPEM   []byte
	Identity string
	TTL      time.Duration
	// DNSNames is authorized only by the internal Core server signing boundary.
	// Node enrollment must never grant server-name authority.
	DNSNames []string
}

func (r CSRSigningRequest) Validate() (*x509.CertificateRequest, error)

func (CSRSigningRequest) ValidateCore added in v0.4.23 

func (r CSRSigningRequest) ValidateCore() (*x509.CertificateRequest, error)

ValidateCore binds DNS SANs to an explicit internal server authorization. The CSR itself is never the source of authority for additional names.

type CertificateRequest 

type CertificateRequest struct {
	CommonName  string
	DNSNames    []string
	IPAddresses []net.IP
	URIs        []*url.URL

type CoreCSRIssuer interface {
	Issuer
	SignCoreCSR(context.Context, CSRSigningRequest) (IssuedCertificate, error)
}

CoreCSRIssuer is the separate managed server-identity signing boundary. Operator-authorized Core keys cannot be signed through node enrollment.

	Dir                    string
	Caddyfile              string

	HealthAuthorizationEnv string
}

func EnsureHTTPGateway 

func EnsureHTTPGateway(ctx context.Context, issuer Issuer, policy Policy, providerDir string, spec HTTPGatewaySpec) (HTTPGatewayFiles, error)

}

type IssuedCertificate 

type IssuedCertificate struct {
	IssuerReference string
	Certificate     []byte
	PrivateKey      []byte
	IssuingCA       []byte
	CAChain         [][]byte
	Serial          string
