Functions

func CheckSignature

func CheckSignature(cert *Certificate, msg []byte, signature []byte) error

CheckSignature verifies that the signature is a valid signature over signed from the certificate.

func InitNodeStakingKeyPair

func InitNodeStakingKeyPair(keyPath, certPath string) error

InitNodeStakingKeyPair generates a self-signed TLS key/cert pair to use in staking. The key and files will be placed at [keyPath] and [certPath], respectively. If there is already a file at [keyPath], returns nil.

func LoadTLSCertFromBytes

func LoadTLSCertFromBytes(keyBytes, certBytes []byte) (*tls.Certificate, error)

func LoadTLSCertFromFiles

func LoadTLSCertFromFiles(keyPath, certPath string) (*tls.Certificate, error)

func NewCertAndKeyBytes

func NewCertAndKeyBytes() ([]byte, []byte, error)

Creates a new staking private key / staking certificate pair. Returns the PEM byte representations of both.

func NewTLSCert

func NewTLSCert() (*tls.Certificate, error)

Types

type Certificate

type Certificate struct {
	Raw       []byte
	PublicKey crypto.PublicKey
}

func ParseCertificate

func ParseCertificate(bytes []byte) (*Certificate, error)

ParseCertificate parses a single certificate from the given ASN.1.

This function does not validate that the certificate is valid to be used against normal TLS implementations.
