Types

type ACMEIssuer 

type ACMEIssuer struct {
	// The URL to the CA's ACME directory endpoint.

	// The URL to the test CA's ACME directory endpoint.
	// This endpoint is only used during retries if there
	// is a failure using the primary CA.
	TestCA string `json:"test_ca,omitempty"`

	// Your email address, so the CA can contact you if necessary.
	// Not required, but strongly recommended to provide one so
	// you can be reached if there is a problem. Your email is
	// not sent to any Caddy mothership or used for any purpose
	// other than ACME transactions.
	Email string `json:"email,omitempty"`

	// If using an ACME CA that requires an external account
	// binding, specify the CA-provided credentials here.
	ExternalAccount *ExternalAccountBinding `json:"external_account,omitempty"`

	// Time to wait before timing out an ACME operation.
	ACMETimeout caddy.Duration `json:"acme_timeout,omitempty"`

	// Configures the various ACME challenge types.
	Challenges *ChallengesConfig `json:"challenges,omitempty"`

	// is internal or for development/testing purposes.
	TrustedRootsPEMFiles []string `json:"trusted_roots_pem_files,omitempty"`
	// contains filtered or unexported fields
}

ACMEIssuer makes an ACME manager for managing certificates using ACME.

TODO: support multiple ACME endpoints (probably requires an array of these structs) - caddy would also have to load certs from the backup CAs if the first one is expired...

type AutomateLoader 

type AutomateLoader []string

AutomateLoader is a no-op certificate loader module that is treated as a special case: it uses this app's automation features to load certificates for the list of hostnames, rather than loading certificates manually.

func (AutomateLoader) CaddyModule 

func (AutomateLoader) CaddyModule() caddy.ModuleInfo

CaddyModule returns the Caddy module information.

type AutomationConfig 

type AutomationConfig struct {
	// The list of automation policies. The first matching

	// On-Demand TLS defers certificate operations to the
	// moment they are needed, e.g. during a TLS handshake.
	// Useful when you don't know all the hostnames at
	// config-time, or when you are not in control of the
	// domain names you are managing certificates for.
	// In 2015, Caddy became the first web server to
	// implement this experimental technology.
	//
	// Note that this field does not enable on-demand TLS,
	// it only configures it for when it is used. To enable
	// it, create an automation policy with `on_demand`.
	OnDemand *OnDemandConfig `json:"on_demand,omitempty"`

	// Caddy staples OCSP (and caches the response) for all
	// qualifying certificates by default. This setting
	// changes how often it scans responses for freshness,
	// and updates them if they are getting stale. Default: 1h
	OCSPCheckInterval caddy.Duration `json:"ocsp_interval,omitempty"`

	MustStaple bool `json:"must_staple,omitempty"`

	// How long before a certificate's expiration to try renewing it,
	// as a function of its total lifetime. As a general and conservative
	// rule, it is a good idea to renew a certificate when it has about
	// 1/3 of its total lifetime remaining. This utilizes the majority
	// of the certificate's lifetime while still saving time to
	// troubleshoot problems. However, for extremely short-lived certs,
	// you may wish to increase the ratio to ~1/2.
	RenewalWindowRatio float64 `json:"renewal_window_ratio,omitempty"`

	// The type of key to generate for certificates.
	// Supported values: `ed25519`, `p256`, `p384`, `rsa2048`, `rsa4096`.
	KeyType string `json:"key_type,omitempty"`

	// Optionally configure a separate storage module associated with this
	// manager, instead of using Caddy's global/default-configured storage.
	StorageRaw json.RawMessage `json:"storage,omitempty" caddy:"namespace=caddy.storage inline_key=module"`

	// If true, certificates will be managed "on demand"; that is, during
	// TLS handshakes or when needed, as opposed to at startup or config
	// load.
	OnDemand bool `json:"on_demand,omitempty"`

	// Issuer stores the decoded issuer parameters. This is only
	// used to populate an underlying certmagic.Config's Issuer
	// field; it is not referenced thereafter.
	Issuer certmagic.Issuer `json:"-"`
	// contains filtered or unexported fields
}

AutomationPolicy designates the policy for automating the management (obtaining, renewal, and revocation) of managed TLS certificates.

An AutomationPolicy value is not valid until it has been provisioned; use the `AddAutomationPolicy()` method on the TLS app to properly provision a new policy.

Provision sets up ap and builds its underlying CertMagic config.

type CertCacheOptions

type HTTPChallengeConfig 

type HTTPChallengeConfig struct {
	// If true, the HTTP challenge will be disabled.
	Disabled bool `json:"disabled,omitempty"`

	// An alternate port on which to service this
	// challenge. Note that the HTTP challenge port is
	// hard-coded into the spec and cannot be changed,

	AlternatePort int `json:"alternate_port,omitempty"`
}

HTTPChallengeConfig configures the ACME HTTP challenge.

	// The validity period of certificates.
	Lifetime caddy.Duration `json:"lifetime,omitempty"`

	// issuance of certificates from handshakes.
	RateLimit *RateLimit `json:"rate_limit,omitempty"`

	// If Caddy needs to obtain or renew a certificate

	// HTTP request to this URL to check if it should be
	// allowed to try to get a certificate for the name
	// in the "domain" query string parameter, like so:

	// anything else will cause it to be denied.
	// Redirects are not followed.
	Ask string `json:"ask,omitempty"`
}

OnDemandConfig configures on-demand TLS, for obtaining needed certificates at handshake-time. Because this feature can easily be abused, you should use this to establish rate limits and/or an internal endpoint that Caddy can "ask" if it should be allowed to manage certificates for a given hostname.

	// Next returns the channel through which the next session
	// ticket keys will be transmitted until doneChan is closed.
	// Keys should be sent on keysChan as they are updated.
	// When doneChan is closed, any resources allocated in
	// Initialize() must be cleaned up.

}

STEKProvider is a type that can provide session ticket ephemeral keys (STEKs).

type SessionTicketService

type TLS 

type TLS struct {
	// Caches certificates in memory for quick use during
	// TLS handshakes. Each key is the name of a certificate
	// loader module. All loaded certificates get pooled
	// into the same cache and may be used to complete TLS
	// handshakes for the relevant server names (SNI).
	// Certificates loaded manually (anything other than
	// "automate") are not automatically managed and will
	// have to be refreshed manually before they expire.
	CertificatesRaw caddy.ModuleMap `json:"certificates,omitempty" caddy:"namespace=tls.certificates"`

	// Configures the automation of certificate management.
