Functions

func HashCert

func HashCert(cert []byte) uint64

HashCert calculates the FNV1a hash of a certificate

Types

type AEAD

type AEAD interface {
	Open(dst, src []byte, packetNumber protocol.PacketNumber, associatedData []byte) ([]byte, error)
	Seal(dst, src []byte, packetNumber protocol.PacketNumber, associatedData []byte) []byte
	Overhead() int
}

An AEAD implements QUIC's authenticated encryption and associated data

func DeriveAESKeys

func DeriveAESKeys(tls TLSExporter, pers protocol.Perspective) (AEAD, error)

DeriveAESKeys derives the AES keys and creates a matching AES-GCM AEAD instance

func DeriveQuicCryptoAESKeys

func DeriveQuicCryptoAESKeys(forwardSecure bool, sharedSecret, nonces []byte, connID protocol.ConnectionID, chlo []byte, scfg []byte, cert []byte, divNonce []byte, pers protocol.Perspective) (AEAD, error)

DeriveQuicCryptoAESKeys derives the client and server keys and creates a matching AES-GCM AEAD instance

func NewAEADAESGCM

func NewAEADAESGCM(otherKey []byte, myKey []byte, otherIV []byte, myIV []byte) (AEAD, error)

NewAEADAESGCM creates a AEAD using AES-GCM

func NewAEADAESGCM12

func NewAEADAESGCM12(otherKey []byte, myKey []byte, otherIV []byte, myIV []byte) (AEAD, error)

NewAEADAESGCM12 creates a AEAD using AES-GCM with 12 bytes tag size

func NewNullAEAD

NewNullAEAD creates a NullAEAD

type CertChain

type CertChain interface {
	SignServerProof(sni string, chlo []byte, serverConfigData []byte) ([]byte, error)
	GetCertsCompressed(sni string, commonSetHashes, cachedHashes []byte) ([]byte, error)
	GetLeafCert(sni string) ([]byte, error)
}

A CertChain holds a certificate and a private key

func NewCertChain

func NewCertChain(tlsConfig *tls.Config) CertChain

NewCertChain loads the key and cert from files

type CertManager

type CertManager interface {
	SetData([]byte) error
	GetCommonCertificateHashes() []byte
	GetLeafCert() []byte
	GetLeafCertHash() (uint64, error)
	VerifyServerProof(proof, chlo, serverConfigData []byte) bool
	Verify(hostname string) error
	GetChain() []*x509.Certificate
}

CertManager manages the certificates sent by the server

func NewCertManager

func NewCertManager(tlsConfig *tls.Config) CertManager

NewCertManager creates a new CertManager

type KeyExchange

type KeyExchange interface {
	PublicKey() []byte
	CalculateSharedKey(otherPublic []byte) ([]byte, error)
}

KeyExchange manages the exchange of keys

func NewCurve25519KEX

func NewCurve25519KEX() (KeyExchange, error)

NewCurve25519KEX creates a new KeyExchange using Curve25519, see https://cr.yp.to/ecdh.html

type TLSExporter

type TLSExporter interface {
	ConnectionState() mint.ConnectionState
	ComputeExporter(label string, context []byte, keyLength int) ([]byte, error)
}

A TLSExporter gets the negotiated ciphersuite and computes exporter
