if err != nil {
  	plog.Info("some error", FositeErrorForLog(err)...)
   ...
 }

Types

type Codec

type Codec interface {
	Encoder
	Decoder
}

Codec is both the encoding and decoding sides of the securecookie.Codec interface. It is interface'd here so that we properly wrap the securecookie dependency.

	Decode(name, value string, into interface{}) error
}

Decoder is the decoding side of the securecookie.Codec interface.

type Encoder

type Encoder interface {
	Encode(name string, value interface{}) (string, error)
}

Encoder is the encoding side of the securecookie.Codec interface.

type TimeoutsConfiguration

type TimeoutsConfiguration struct {
	// The length of time that our state param that we encrypt and pass to the upstream OIDC IDP should be considered
	// valid. If a state param generated by the authorize endpoint is sent to the callback endpoint after this much
	// time has passed, then the callback endpoint should reject it. This allows us to set a limit on how long
	// the end user has to finish their login with the upstream IDP, including the time that it takes to fumble
	// with password manager and two-factor authenticator apps, and also accounting for taking a coffee break while
	// the browser is sitting at the upstream IDP's login page.
	UpstreamStateParamLifespan time.Duration

	// How long an authcode issued by the callback endpoint is valid. This determines how much time the end user
	// has to come back to exchange the authcode for tokens at the token endpoint.
	AuthorizeCodeLifespan time.Duration

	// The lifetime of an downstream access token issued by the token endpoint. Access tokens should generally
	// be fairly short-lived.
	AccessTokenLifespan time.Duration

	// The lifetime of an downstream ID token issued by the token endpoint. This should generally be the same
	// as the AccessTokenLifespan, or longer if it would be useful for the user's proof of identity to be valid
	// for longer than their proof of authorization.
	IDTokenLifespan time.Duration

	// The lifetime of an downstream refresh token issued by the token endpoint. This should generally be
	// significantly longer than the access token lifetime, so it can be used to refresh the access token
	// multiple times. Once the refresh token expires, the user's session is over and they will need
	// to start a new authorization request, which will require them to log in again with the upstream IDP
	// in their web browser.
	RefreshTokenLifespan time.Duration

	// AuthorizationCodeSessionStorageLifetime is the length of time after which an authcode is allowed to be garbage
	// collected from storage. Authcodes are kept in storage after they are redeemed to allow the system to mark the
	// authcode as already used, so it can reject any future uses of the same authcode with special case handling which
	// include revoking the access and refresh tokens associated with the session. Therefore, this should be
	// significantly longer than the AuthorizeCodeLifespan, and there is probably no reason to make it longer than
	// the sum of the AuthorizeCodeLifespan and the RefreshTokenLifespan.
	AuthorizationCodeSessionStorageLifetime time.Duration

	// PKCESessionStorageLifetime is the length of time after which PKCE data is allowed to be garbage collected from
	// storage. PKCE sessions are closely related to authorization code sessions. After the authcode is successfully
	// redeemed, the PKCE session is explicitly deleted. After the authcode expires, the PKCE session is no longer needed,
	// but it is not explicitly deleted. Therefore, this can be just slightly longer than the AuthorizeCodeLifespan. We'll
	// avoid making it exactly the same as AuthorizeCodeLifespan to avoid any chance of the garbage collector deleting it
	// while it is being used.
	PKCESessionStorageLifetime time.Duration

	// OIDCSessionStorageLifetime is the length of time after which the OIDC session data related to an authcode
	// is allowed to be garbage collected from storage. Due to a bug in an underlying library, these are not explicitly
	// deleted. Similar to the PKCE session, they are not needed anymore after the corresponding authcode has expired.
	// Therefore, this can be just slightly longer than the AuthorizeCodeLifespan. We'll avoid making it exactly the same
	// as AuthorizeCodeLifespan to avoid any chance of the garbage collector deleting it while it is being used.
	OIDCSessionStorageLifetime time.Duration

	// AccessTokenSessionStorageLifetime is the length of time after which an access token's session data is allowed
	// to be garbage collected from storage.  These must exist in storage for as long as the refresh token is valid
	// or else the refresh flow will not work properly. So this must be longer than RefreshTokenLifespan.
	AccessTokenSessionStorageLifetime time.Duration

	// RefreshTokenSessionStorageLifetime is the length of time after which a refresh token's session data is allowed
	// to be garbage collected from storage. These must exist in storage for as long as the refresh token is valid.
	// Therefore, this can be just slightly longer than the RefreshTokenLifespan. We'll avoid making it exactly the same
	// as RefreshTokenLifespan to avoid any chance of the garbage collector deleting it while it is being used.
	// If an expired token is still stored when the user tries to refresh it, then they will get a more specific
	// error message telling them that the token is expired, rather than a more generic error that is returned
	// when the token does not exist. If this is desirable, then the RefreshTokenSessionStorageLifetime can be made
	// to be significantly larger than RefreshTokenLifespan, at the cost of slower cleanup.
	RefreshTokenSessionStorageLifetime time.Duration

type UpstreamLDAPIdentityProvidersLister

type UpstreamLDAPIdentityProvidersLister interface {

type UpstreamOIDCIdentityProvidersLister

type UpstreamOIDCIdentityProvidersLister interface {

type UpstreamStateParamData

type UpstreamStateParamData struct {
	AuthParams    string              `json:"p"`
	UpstreamName  string              `json:"u"`
	Nonce         nonce.Nonce         `json:"n"`
	CSRFToken     csrftoken.CSRFToken `json:"c"`
	PKCECode      pkce.Code           `json:"k"`
	FormatVersion string              `json:"v"`
}

UpstreamStateParamData is the format of the state parameter that we use when we communicate to an upstream OIDC provider.

Keep the JSON to a minimal size because the upstream provider could impose size limitations on the state param.
