Functions

func DeriveKey

func DeriveKey(secret, salt, info []byte, length uint) ([]byte, error)

DeriveKey derives a key from a secret.

func GenerateCertificateSerialNumber

func GenerateCertificateSerialNumber() (*big.Int, error)

GenerateCertificateSerialNumber generates a random serial number for an X.509 certificate.

func GenerateRandomBytes

func GenerateRandomBytes(length int) ([]byte, error)

GenerateRandomBytes reads length bytes from getrandom(2) if available, /dev/urandom otherwise.

func PemToX509Cert

func PemToX509Cert(raw []byte) (*x509.Certificate, error)

PemToX509Cert takes a list of PEM encoded certificates, parses the first one and returns it.
