Functions

func DefaultSchemesPath

func DefaultSchemesPath() string

DefaultSchemesPath returns the default path for IRMA schemes, using XDG Base Directory Specification https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html:

  • %LOCALAPPDATA% (i.e. C:\Users\$user\AppData\Local) if on Windows,
  • $XDG_DATA_HOME if set, otherwise $HOME/.local/share
  • $XDG_DATA_DIRS if set, otherwise /usr/local/share/ and /usr/share/
  • then the OSes temp dir (os.TempDir()),

returning the first of these that exists or can be created.

func JsonResponse

func JsonResponse(v interface{}, err *irma.RemoteError) (int, []byte)

JsonResponse JSON-marshals the specified object or error and returns it along with a suitable HTTP status code

func LocalIP

func LocalIP() (string, error)

LocalIP returns the IP address of one of the (non-loopback) network interfaces

func ParseSessionRequest

func ParseSessionRequest(request interface{}) (irma.RequestorRequest, error)

ParseSessionRequest attempts to parse the input as an irma.RequestorRequest instance, accepting (skipping "irma.")

  • RequestorRequest instances directly (ServiceProviderRequest, SignatureRequestorRequest, IdentityProviderRequest)
  • SessionRequest instances (DisclosureRequest, SignatureRequest, IssuanceRequest)
  • JSON representations ([]byte or string) of any of the above.

Types

type Configuration

type Configuration struct {
	// irma_configuration. If not given, this will be popupated using SchemesPath.
	IrmaConfiguration *irma.Configuration `json:"-"`
	// Path to IRMA schemes to parse into IrmaConfiguration (only used if IrmaConfiguration == nil).
	// If left empty, default value is taken using DefaultSchemesPath().
	// If an empty folder is specified, default schemes (irma-demo and pbdf) are downloaded into it.

	Verbose int `json:"verbose" mapstructure:"verbose"`
	// Don't log anything at all
	Quiet bool `json:"quiet" mapstructure:"quiet"`
	// Output structured log in JSON format

}

Configuration contains configuration for the irmaserver library and irmad.
