Functions

func FileDescriptorSet

func FileDescriptorSet() *descriptorpb.FileDescriptorSet

FileDescriptorSet returns a descriptor set for this proto package, which includes all defined services, and all transitive dependencies.

Will not return nil.

Do NOT modify the returned descriptor.

func RegisterTokenMinterServer

func RegisterTokenMinterServer(s grpc.ServiceRegistrar, srv TokenMinterServer)

Types

type ErrorCode

type ErrorCode int32

Possible kinds of fatal errors.

Non fatal errors are returned as grpc.Internal errors instead.

	ErrorCode_UNSUPPORTED_SIGNATURE       ErrorCode = 1 // used signature_algorithm is not supported

	ErrorCode_BAD_TIMESTAMP               ErrorCode = 3 // issued_at field is wrong
	ErrorCode_BAD_CERTIFICATE_FORMAT      ErrorCode = 4 // malformed or unsupported certificate
	ErrorCode_BAD_SIGNATURE               ErrorCode = 5 // signature doesn't match or can't be verified
	ErrorCode_UNTRUSTED_CERTIFICATE       ErrorCode = 6 // invalid certificate or can't verify it yet

type LuciMachineToken

type LuciMachineToken struct {
	MachineToken string                 `protobuf:"bytes,1,opt,name=machine_token,json=machineToken,proto3" json:"machine_token,omitempty"` // the actual token

	// contains filtered or unexported fields
}

LuciMachineToken is short lived machine token.

It is understood only by LUCI backends. It is a bearer token, that embeds machine hostname and details about the machine certificate it was issued for. It has short lifetime (usually 1h).

It is expected to be sent to backends in 'X-Luci-Machine-Token' HTTP header.

The token here is supposed to be treated as an opaque base64-encoded blob, but in reality it is serialized MachineTokenEnvelope, see machine_token.proto and read the comment there for more info about the token format.
