var CommonNameUserConversion = UserConversionFunc(func(chain []*x509.Certificate) (user.Info, bool, error) {
	if len(chain[0].Subject.CommonName) == 0 {
		return nil, false, nil
	}
	return &user.DefaultInfo{Name: chain[0].Subject.CommonName}, true, nil
})

CommonNameUserConversion builds user info from a certificate chain using the subject's CommonName

var DNSNameUserConversion = UserConversionFunc(func(chain []*x509.Certificate) (user.Info, bool, error) {
	if len(chain[0].DNSNames) == 0 {
		return nil, false, nil
	}
	return &user.DefaultInfo{Name: chain[0].DNSNames[0]}, true, nil
})

DNSNameUserConversion builds user info from a certificate chain using the first DNSName on the certificate

var EmailAddressUserConversion = UserConversionFunc(func(chain []*x509.Certificate) (user.Info, bool, error) {
	if len(chain[0].EmailAddresses) == 0 {
		return nil, false, nil
	}
	return &user.DefaultInfo{Name: chain[0].EmailAddresses[0]}, true, nil
})

EmailAddressUserConversion builds user info from a certificate chain using the first EmailAddress on the certificate

var SubjectToUserConversion = UserConversionFunc(func(chain []*x509.Certificate) (user.Info, bool, error) {
	user := SubjectToUser(chain[0].Subject)
	if len(user.GetName()) == 0 {
		return nil, false, nil
	}
	return user, true, nil
})

SubjectToUserConversion calls SubjectToUser on the subject of the first certificate in the chain. If the resulting user has no name, it returns nil, false, nil

Functions

func DefaultVerifyOptions

func DefaultVerifyOptions() x509.VerifyOptions

DefaultVerifyOptions returns VerifyOptions that use the system root certificates, current time, and requires certificates to be valid for client auth (x509.ExtKeyUsageClientAuth)

func NewVerifier added in v0.4.2

func SubjectToUser added in v0.3.1

func SubjectToUser(subject pkix.Name) user.Info

func UserToSubject added in v0.3.1

func UserToSubject(u user.Info) pkix.Name

Types

type Authenticator

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

Authenticator implements request.Authenticator by extracting user info from verified client certificates

func New

New returns a request.Authenticator that verifies client certificates using the provided VerifyOptions, and converts valid certificate chains into user.Info using the provided UserConversion

func (*Authenticator) AuthenticateRequest

func (a *Authenticator) AuthenticateRequest(req *http.Request) (user.Info, bool, error)

AuthenticateRequest authenticates the request using presented client certificates

type UserConversion

type UserConversion interface {
	User(chain []*x509.Certificate) (user.Info, bool, error)
}

UserConversion defines an interface for extracting user info from a client certificate chain

type UserConversionFunc

type UserConversionFunc func(chain []*x509.Certificate) (user.Info, bool, error)

UserConversionFunc is a function that implements the UserConversion interface.

func (UserConversionFunc) User

func (f UserConversionFunc) User(chain []*x509.Certificate) (user.Info, bool, error)

User implements x509.UserConversion

type Verifier added in v0.4.2

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

Verifier implements request.Authenticator by verifying a client cert on the request, then delegating to the wrapped auth

func (*Verifier) AuthenticateRequest added in v0.4.2

func (a *Verifier) AuthenticateRequest(req *http.Request) (user.Info, bool, error)

AuthenticateRequest verifies the presented client certificates, then delegates to the wrapped auth
