Functions

func SetHandshakeInfo

func SetHandshakeInfo(addr resolver.Address, hInfo *HandshakeInfo) resolver.Address

SetHandshakeInfo returns a copy of addr in which the Attributes field is updated with hInfo.

Types

type HandshakeInfo

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

HandshakeInfo wraps all the security configuration required by client and server handshake methods in xds credentials. The xDS implementation will be responsible for populating these fields.

Safe for concurrent access.

func GetHandshakeInfo

func GetHandshakeInfo(attr *attributes.Attributes) *HandshakeInfo

GetHandshakeInfo returns a pointer to the HandshakeInfo stored in attr.

func NewHandshakeInfo

func NewHandshakeInfo(root, identity certprovider.Provider) *HandshakeInfo

NewHandshakeInfo returns a new instance of HandshakeInfo with the given root and identity certificate providers.

func (*HandshakeInfo) ClientSideTLSConfig

func (hi *HandshakeInfo) ClientSideTLSConfig(ctx context.Context) (*tls.Config, error)

ClientSideTLSConfig constructs a tls.Config to be used in a client-side handshake based on the contents of the HandshakeInfo.

func (*HandshakeInfo) Equal

func (hi *HandshakeInfo) Equal(o interface{}) bool

Equal reports whether the handshake info structs are identical (have the same pointer). This is sufficient as all subconns from one CDS balancer use the same one.

func (*HandshakeInfo) GetSANMatchersForTesting

func (hi *HandshakeInfo) GetSANMatchersForTesting() []matcher.StringMatcher

GetSANMatchersForTesting returns the SAN matchers stored in HandshakeInfo. To be used only for testing purposes.

func (*HandshakeInfo) MatchingSANExists

func (hi *HandshakeInfo) MatchingSANExists(cert *x509.Certificate) bool

MatchingSANExists returns true if the SANs contained in cert match the criteria enforced by the list of SAN matchers in HandshakeInfo.

If the list of SAN matchers in the HandshakeInfo is empty, this function returns true for all input certificates.

func (*HandshakeInfo) ServerSideTLSConfig

func (hi *HandshakeInfo) ServerSideTLSConfig(ctx context.Context) (*tls.Config, error)

ServerSideTLSConfig constructs a tls.Config to be used in a server-side handshake based on the contents of the HandshakeInfo.

func (*HandshakeInfo) SetIdentityCertProvider

func (hi *HandshakeInfo) SetIdentityCertProvider(identity certprovider.Provider)

SetIdentityCertProvider updates the identity certificate provider.

func (*HandshakeInfo) SetRequireClientCert

func (hi *HandshakeInfo) SetRequireClientCert(require bool)

SetRequireClientCert updates whether a client cert is required during the ServerHandshake(). A value of true indicates that we are performing mTLS.

func (*HandshakeInfo) SetRootCertProvider

func (hi *HandshakeInfo) SetRootCertProvider(root certprovider.Provider)

SetRootCertProvider updates the root certificate provider.

func (*HandshakeInfo) SetSANMatchers

func (hi *HandshakeInfo) SetSANMatchers(sanMatchers []matcher.StringMatcher)

SetSANMatchers updates the list of SAN matchers.

func (*HandshakeInfo) UseFallbackCreds

func (hi *HandshakeInfo) UseFallbackCreds() bool

UseFallbackCreds returns true when fallback credentials are to be used based on the contents of the HandshakeInfo.
