Functions

func AppendNewCertsToTrustRoots

func AppendNewCertsToTrustRoots(tlsTrustRoots *ChainTrustRoots, chainId string, certPemBytes []byte) (bool, error)

AppendNewCertsToTrustRoots will load all cert from cert pem bytes, then append them to chain trust roots.

func GetCertAndPeerIdWithKeyPair

func GetCertAndPeerIdWithKeyPair(certPEMBlock []byte, keyPEMBlock []byte) (*tls.Certificate, string, error)

GetCertAndPeerIdWithKeyPair will create a tls cert with x509 key pair and load the peer id from cert.

func NewTlsConfig

func NewTlsConfig(
	certificate tls.Certificate,
	certValidator *CertValidator,
) (*tls.Config, error)

NewTlsConfig create a new tls config for tls handshake.

Types

type CertValidator

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

CertValidator wraps a ChainTrustRoots instance and a common.MemberStatusValidator. It provides a function for verifying peer certificate when tls handshaking. In handshaking process, the function will load remote tls certificate and verify it by chain trust roots, also load remote peer id and cert id. All these infos will stored in validator. These infos could be queried with QueryDerivedInfoWithPeerId function, and could be removed with CleanDerivedInfoWithPeerId function.

func NewCertValidator

func NewCertValidator(tlsTrustRoots *ChainTrustRoots, memberStatusValidator *common.MemberStatusValidator) *CertValidator

NewCertValidator create a new CertValidator instance.

func (*CertValidator) QueryDerivedInfoWithPeerId

func (v *CertValidator) QueryDerivedInfoWithPeerId(peerId string) *DerivedInfoWithCert

QueryDerivedInfoWithPeerId return all infos that loaded with VerifyPeerCertificateFunc and stored in validator.

func (*CertValidator) VerifyPeerCertificateFunc

func (v *CertValidator) VerifyPeerCertificateFunc() func(rawCerts [][]byte, _ [][]*x509.Certificate) error

VerifyPeerCertificateFunc provides a function for verify peer certificate in tls config. In handshaking process, the function will load remote tls certificate and verify it by chain trust roots, also load remote peer id and cert id. All these infos will stored in validator.

type ChainTrustRoots

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

ChainTrustRoots keep the trust root cert pools and the trust intermediates cert pools of all chains.

func BuildTlsTrustRoots

func BuildTlsTrustRoots(chainTrustRoots map[string][][]byte) (*ChainTrustRoots, error)

BuildTlsTrustRoots build the cert pool with cert bytes of chain.

func NewChainTrustRoots

func NewChainTrustRoots() *ChainTrustRoots

NewChainTrustRoots create a new ChainTrustRoots instance.

func (*ChainTrustRoots) AddIntermediates

func (ctr *ChainTrustRoots) AddIntermediates(chainId string, intermediates *x509.Certificate)

AddIntermediates add a trust intermediates cert to cert pool.

func (*ChainTrustRoots) AddRoot

func (ctr *ChainTrustRoots) AddRoot(chainId string, root *x509.Certificate)

AddRoot add a trust root cert to cert pool.

func (*ChainTrustRoots) AppendIntermediatesFromPem

func (ctr *ChainTrustRoots) AppendIntermediatesFromPem(chainId string, intermediatesPem []byte) bool

AppendIntermediatesFromPem append trust intermediates certs from pem bytes to cert pool.

func (*ChainTrustRoots) AppendRootsFromPem

func (ctr *ChainTrustRoots) AppendRootsFromPem(chainId string, rootPem []byte) bool

AppendRootsFromPem append trust root certs from pem bytes to cert pool.

func (*ChainTrustRoots) IntermediatesPool

func (ctr *ChainTrustRoots) IntermediatesPool(chainId string) (*x509.CertPool, bool)

IntermediatesPool return the trust intermediates cert pool of the chain which id is the id given.

func (*ChainTrustRoots) RefreshIntermediatesFromPem

func (ctr *ChainTrustRoots) RefreshIntermediatesFromPem(chainId string, intermediatesPem [][]byte) bool

RefreshIntermediatesFromPem reset all trust intermediates certs from pem bytes array to cert pool.

func (*ChainTrustRoots) RefreshRootsFromPem

func (ctr *ChainTrustRoots) RefreshRootsFromPem(chainId string, rootsPem [][]byte) bool

RefreshRootsFromPem reset all trust root certs from pem bytes array to cert pool.

func (*ChainTrustRoots) RootsPool

func (ctr *ChainTrustRoots) RootsPool(chainId string) (*x509.CertPool, bool)

RootsPool return the trust root cert pool of the chain which id is the id given.

func (*ChainTrustRoots) VerifyCert

func (ctr *ChainTrustRoots) VerifyCert(cert *x509.Certificate) ([]string, error)

VerifyCert verify the cert given. If ok, return chain id list.

func (*ChainTrustRoots) VerifyCertOfChain

func (ctr *ChainTrustRoots) VerifyCertOfChain(chainId string, cert *x509.Certificate) bool

VerifyCertOfChain verify the cert given with chainId. If ok, return true.

type DerivedInfoWithCert

type DerivedInfoWithCert struct {
	TlsCertBytes []byte
	ChainIds     []string
	PeerId       string
	CertId       string
}

DerivedInfoWithCert contains infos loaded from tls cert when verifying peer certificate.
