Functions

func CertificatesWithSamePublicKey added in v1.4.9

func CertificatesWithSamePublicKey(der1, der2 []byte) error

CertificatesWithSamePublicKey returns nil if both byte slices are valid DER encoding of certificates with the same public key.

func ExpiresAt added in v1.1.0

func ExpiresAt(identityBytes []byte) time.Time

ExpiresAt returns when the given identity expires, or a zero time.Time in case we cannot determine that

func GetRandomBytes

func GetRandomBytes(len int) ([]byte, error)

GetRandomBytes returns len random looking bytes

func GetRandomNonce

func GetRandomNonce() ([]byte, error)

GetRandomNonce returns a random byte array of length NonceSize

func LogNonPubKeyMismatchErr added in v1.4.9

func LogNonPubKeyMismatchErr(log func(template string, args ...interface{}), err error, cert1DER, cert2DER []byte)

LogNonPubKeyMismatchErr logs an error which is not an ErrPubKeyMismatch error

func TrackExpiration added in v1.4.4

func TrackExpiration(tls bool, serverCert []byte, clientCertChain [][]byte, sIDBytes []byte, info MessageFunc, warn MessageFunc, now time.Time, s Scheduler)

TrackExpiration warns a week before one of the certificates expires

Types

type IdentitySerializer added in v1.2.0

type IdentitySerializer interface {
	// Serialize converts an identity to bytes
	Serialize() ([]byte, error)
}

IdentitySerializer serializes identities

type LocalSigner

type LocalSigner interface {
	SignatureHeaderMaker
	Signer
}

LocalSigner is a temporary stub interface which will be implemented by the local MSP

type MessageFunc added in v1.4.9

type MessageFunc func(format string, args ...interface{})

MessageFunc notifies a message happened with the given format, and can be replaced with Warnf or Infof of a logger.

type Scheduler added in v1.4.4

type Scheduler func(d time.Duration, f func()) *time.Timer

Scheduler invokes f after d time, and can be replaced with time.AfterFunc.

type SignatureHeaderCreator added in v1.2.0

type SignatureHeaderCreator struct {
	SignerSupport
}

SignatureHeaderCreator creates signature headers

func NewSignatureHeaderCreator added in v1.2.0

func NewSignatureHeaderCreator(ss SignerSupport) *SignatureHeaderCreator

NewSignatureHeaderCreator creates new signature headers

func (*SignatureHeaderCreator) NewSignatureHeader added in v1.2.0

func (bs *SignatureHeaderCreator) NewSignatureHeader() (*cb.SignatureHeader, error)

NewSignatureHeader creates a SignatureHeader with the correct signing identity and a valid nonce

type SignatureHeaderMaker added in v1.2.0

type SignatureHeaderMaker interface {
	// NewSignatureHeader creates a SignatureHeader with the correct signing identity and a valid nonce
	NewSignatureHeader() (*cb.SignatureHeader, error)
}

SignatureHeaderMaker creates a new SignatureHeader

type Signer added in v1.2.0

type Signer interface {
	// Sign a message and return the signature over the digest, or error on failure
	Sign(message []byte) ([]byte, error)
}

Signer signs messages

type SignerSupport added in v1.2.0

type SignerSupport interface {
	Signer
	IdentitySerializer
}

SignerSupport implements the needed support for LocalSigner
