func VerifyPubKey

func VerifyPubKey(r *http.Request) (*asymkey_model.PublicKey, error)

Types

type Basic

type Basic struct{}

Basic implements the Auth interface and authenticates requests (API requests only) by looking for Basic authentication data or "x-oauth-basic" token in the "Authorization" header.

func (*Basic) Name

func (b *Basic) Name() string

Name represents the name of auth method

func (*Basic) Verify

func (b *Basic) Verify(req *http.Request, w http.ResponseWriter, store DataStore, sess SessionStore) (*user_model.User, error)

Verify extracts and validates Basic data (username and password/token) from the "Authorization" header of the request and returns the corresponding user object for that name/token on successful validation. Returns nil if header is empty or validation fails.

type DataStore

type DataStore middleware.ContextDataStore

DataStore represents a data store

type Group

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

Group implements the Auth interface with serval Auth.

func NewGroup

func NewGroup(methods ...Method) *Group

NewGroup creates a new auth group

func (*Group) Add

func (b *Group) Add(method Method)

Add adds a new method to group

func (*Group) Name

func (b *Group) Name() string

Name returns group's methods name

func (*Group) Verify

func (b *Group) Verify(req *http.Request, w http.ResponseWriter, store DataStore, sess SessionStore) (*user_model.User, error)

type HTTPSign

type HTTPSign struct{}

HTTPSign implements the Auth interface and authenticates requests (API requests only) by looking for http signature data in the "Signature" header. more information can be found on https://github.com/go-fed/httpsig

func (*HTTPSign) Name

func (h *HTTPSign) Name() string

Name represents the name of auth method

func (*HTTPSign) Verify

func (h *HTTPSign) Verify(req *http.Request, w http.ResponseWriter, store DataStore, sess SessionStore) (*user_model.User, error)

Verify extracts and validates HTTPsign from the Signature header of the request and returns the corresponding user object on successful validation. Returns nil if header is empty or validation fails.

type LocalTwoFASkipper

type LocalTwoFASkipper interface {
	IsSkipLocalTwoFA() bool
}

LocalTwoFASkipper represents a source of authentication that can skip local 2fa

type Method

type Method interface {
	// Verify tries to verify the authentication data contained in the request.
	// If verification is successful returns either an existing user object (with id > 0)
	// or a new user object (with id = 0) populated with the information that was found
	// in the authentication data (username or email).
	// Second argument returns err if verification fails, otherwise
	// First return argument returns nil if no matched verification condition
	Verify(http *http.Request, w http.ResponseWriter, store DataStore, sess SessionStore) (*user_model.User, error)

	Name() string
}

Method represents an authentication method (plugin) for HTTP requests.

type OAuth2

type OAuth2 struct{}

OAuth2 implements the Auth interface and authenticates requests (API requests only) by looking for an OAuth token in query parameters or the "Authorization" header.

func (*OAuth2) Name

func (o *OAuth2) Name() string

Name represents the name of auth method

func (*OAuth2) Verify

func (o *OAuth2) Verify(req *http.Request, w http.ResponseWriter, store DataStore, sess SessionStore) (*user_model.User, error)

Verify extracts the user ID from the OAuth token in the query parameters or the "Authorization" header and returns the corresponding user object for that ID. If verification is successful returns an existing user object. Returns nil if verification fails.

type PasswordAuthenticator

type PasswordAuthenticator interface {
	Authenticate(ctx context.Context, user *user_model.User, login, password string) (*user_model.User, error)
}

PasswordAuthenticator represents a source of authentication

type ReverseProxy

type ReverseProxy struct{}

ReverseProxy implements the Auth interface, but actually relies on a reverse proxy for authentication of users. On successful authentication the proxy is expected to populate the username in the "setting.ReverseProxyAuthUser" header. Optionally it can also populate the email of the user in the "setting.ReverseProxyAuthEmail" header.

func (*ReverseProxy) Name

func (r *ReverseProxy) Name() string

Name represents the name of auth method

func (*ReverseProxy) Verify

func (r *ReverseProxy) Verify(req *http.Request, w http.ResponseWriter, store DataStore, sess SessionStore) (*user_model.User, error)

Verify attempts to load a user object based on headers sent by the reverse proxy. First it will attempt to load it based on the username (see docs for getUserFromAuthUser), and failing that it will attempt to load it based on the email (see docs for getUserFromAuthEmail). Returns nil if the headers are empty or the user is not found.

type SSPI

type SSPI struct{}

SSPI implements the SingleSignOn interface and authenticates requests via the built-in SSPI module in Windows for SPNEGO authentication. The SSPI plugin is expected to be executed last, as it returns 401 status code if negotiation fails (or if negotiation should continue), which would prevent other authentication methods to execute at all.

func (*SSPI) Name

func (s *SSPI) Name() string

Name represents the name of auth method

func (*SSPI) Verify

func (s *SSPI) Verify(req *http.Request, w http.ResponseWriter, store DataStore, sess SessionStore) (*user_model.User, error)

Verify uses SSPI (Windows implementation of SPNEGO) to authenticate the request. If authentication is successful, returns the corresponding user object. If negotiation should continue or authentication fails, immediately returns a 401 HTTP response code, as required by the SPNEGO protocol.

type SSPIAuth

type SSPIAuth interface {
	AppendAuthenticateHeader(w http.ResponseWriter, data string)
	Authenticate(r *http.Request, w http.ResponseWriter) (userInfo *SSPIUserInfo, outToken string, err error)
}

	Username string   // Name of user, usually in the form DOMAIN\User
	Groups   []string // The global groups the user is a member of
}

SessionStore represents a session store

type SynchronizableSource

type SynchronizableSource interface {
	Sync(ctx context.Context, updateExisting bool) error
}

SynchronizableSource represents a source that can synchronize users
