const DefaultMaxMsgSize = 1024 * 1024 * 20

DefaultMaxMsgSize use 20MB as the default message size limit. grpc library default is 4MB

Functions

func DefaultClientTLSConfig

func DefaultClientTLSConfig(publicKey crypto.PublicKey) (*tls.Config, error)

DefaultClientTLSConfig returns the default TLS client config with the given public key for a secure GRPC client The TLSConfig verifies that the server certifcate is valid and has the correct signature

func DefaultServerTLSConfig

func DefaultServerTLSConfig(cert *tls.Certificate) *tls.Config

DefaultServerTLSConfig returns the default TLS server config with the given cert for a secure GRPC server

func IsServerAuthError

func IsServerAuthError(err error) bool

IsServerAuthError checks if the input error is of a ServerAuthError type

func SecureGRPCDialOpt

func SecureGRPCDialOpt(publicKeyHex string) (grpc.DialOption, error)

SecureGRPCDialOpt creates a secure GRPC dial option with TLS config

func X509Certificate

func X509Certificate(privKey crypto.PrivateKey) (*tls.Certificate, error)

X509Certificate generates a self-signed x509 TLS certificate from the given key. The generated certificate includes a libp2p extension that specifies the public key and the signature. The certificate does not include any SAN extension.

Types

type ServerAuthError

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

ServerAuthError is an error returned when the server authentication fails

func (ServerAuthError) Error

func (e ServerAuthError) Error() string
