package alts

import "google.golang.org/grpc/credentials/alts"

Package alts implements the ALTS credential support by gRPC library, which encapsulates all the state needed by a client to authenticate with a server using ALTS and make various assertions, e.g., about the client's identity, role, or whether it is authorized to make a particular call. This package is experimental.

Variables

var (

    // ErrUntrustedPlatform is returned from ClientHandshake and
    // ServerHandshake is running on a platform where the trustworthiness of
    // the handshaker service is not guaranteed.
    ErrUntrustedPlatform = errors.New("ALTS: untrusted platform. ALTS is only supported on GCP")
)

func NewClientCreds Uses

func NewClientCreds(opts *ClientOptions) credentials.TransportCredentials

NewClientCreds constructs a client-side ALTS TransportCredentials object.

func NewServerCreds Uses

func NewServerCreds(opts *ServerOptions) credentials.TransportCredentials

NewServerCreds constructs a server-side ALTS TransportCredentials object.

type AuthInfo Uses

type AuthInfo interface {
    // ApplicationProtocol returns application protocol negotiated for the
    // ALTS connection.
    ApplicationProtocol() string
    // RecordProtocol returns the record protocol negotiated for the ALTS
    // connection.
    RecordProtocol() string
    // SecurityLevel returns the security level of the created ALTS secure
    // channel.
    SecurityLevel() altspb.SecurityLevel
    // PeerServiceAccount returns the peer service account.
    PeerServiceAccount() string
    // LocalServiceAccount returns the local service account.
    LocalServiceAccount() string
    // PeerRPCVersions returns the RPC version supported by the peer.
    PeerRPCVersions() *altspb.RpcProtocolVersions
}

AuthInfo exposes security information from the ALTS handshake to the application. This interface is to be implemented by ALTS. Users should not need a brand new implementation of this interface. For situations like testing, any new implementation should embed this interface. This allows ALTS to add new methods to this interface.

func AuthInfoFromContext Uses

func AuthInfoFromContext(ctx context.Context) (AuthInfo, error)

AuthInfoFromContext extracts the alts.AuthInfo object from the given context, if it exists. This API should be used by gRPC server RPC handlers to get information about the communicating peer. For client-side, use grpc.Peer() CallOption.

func AuthInfoFromPeer Uses

func AuthInfoFromPeer(p *peer.Peer) (AuthInfo, error)

AuthInfoFromPeer extracts the alts.AuthInfo object from the given peer, if it exists. This API should be used by gRPC clients after obtaining a peer object using the grpc.Peer() CallOption.

type ClientOptions Uses

type ClientOptions struct {
    // TargetServiceAccounts contains a list of expected target service
    // accounts.
    TargetServiceAccounts []string
    // HandshakerServiceAddress represents the ALTS handshaker gRPC service
    // address to connect to.
    HandshakerServiceAddress string
}

ClientOptions contains the client-side options of an ALTS channel. These options will be passed to the underlying ALTS handshaker.

func DefaultClientOptions Uses

func DefaultClientOptions() *ClientOptions

DefaultClientOptions creates a new ClientOptions object with the default values.

type ServerOptions Uses

type ServerOptions struct {
    // HandshakerServiceAddress represents the ALTS handshaker gRPC service
    // address to connect to.
    HandshakerServiceAddress string
}

ServerOptions contains the server-side options of an ALTS channel. These options will be passed to the underlying ALTS handshaker.

func DefaultServerOptions Uses

func DefaultServerOptions() *ServerOptions

DefaultServerOptions creates a new ServerOptions object with the default values.
