var (
	// AttrOID is the ASN.1 object identifier for an attribute extension in an
	// X509 certificate
	AttrOID = asn1.ObjectIdentifier{1, 2, 3, 4, 5, 6, 7, 8, 1}

Types

type Attribute

type Attribute interface {
	// GetName returns the name of the attribute
	GetName() string
	// GetValue returns the value of the attribute
	GetValue() string
}

Attribute is a name/value pair

type AttributeRequest

type AttributeRequest interface {
	// GetName returns the name of an attribute
	GetName() string
	// IsRequired returns true if the attribute is required
	IsRequired() bool
}

AttributeRequest is a request for an attribute

type Attributes

type Attributes struct {
	Attrs map[string]string `json:"attrs"`
}

Attributes contains attribute names and values

func (*Attributes) Contains

func (a *Attributes) Contains(name string) bool

Contains returns true if the named attribute is found

func (*Attributes) Names

func (a *Attributes) Names() []string

Names returns the names of the attributes

func (*Attributes) True

func (a *Attributes) True(name string) error

True returns nil if the value of attribute 'name' is true; otherwise, an appropriate error is returned.

func (*Attributes) Value

func (a *Attributes) Value(name string) (string, bool, error)

Value returns an attribute's value

type Mgr

type Mgr struct{}

Mgr is the attribute manager and is the main object for this package

func New

func New() *Mgr

New constructs an attribute manager

func (*Mgr) AddAttributesToCert

func (mgr *Mgr) AddAttributesToCert(attrs *Attributes, cert *x509.Certificate) error

AddAttributesToCert adds public attribute info to an X509 certificate.

func (*Mgr) GetAttributesFromCert

func (mgr *Mgr) GetAttributesFromCert(cert *x509.Certificate) (*Attributes, error)

GetAttributesFromCert gets the attributes from a certificate.

func (*Mgr) GetAttributesFromIdemix

func (mgr *Mgr) GetAttributesFromIdemix(creator []byte) (*Attributes, error)

GetAttributesFromIdemix ...

func (*Mgr) ProcessAttributeRequests

func (mgr *Mgr) ProcessAttributeRequests(requests []AttributeRequest, attributes []Attribute) (*Attributes, error)

ProcessAttributeRequests takes an array of attribute requests and an identity's attributes and returns an Attributes object containing the requested attributes.

func (*Mgr) ProcessAttributeRequestsForCert

func (mgr *Mgr) ProcessAttributeRequestsForCert(requests []AttributeRequest, attributes []Attribute, cert *x509.Certificate) error

ProcessAttributeRequestsForCert add attributes to an X509 certificate, given attribute requests and attributes.
