Functions

func GetConfigForClientFunc

func GetConfigForClientFunc(certFile, keyFile, caCertFile string) func(*tls.ClientHelloInfo) (*tls.Config, error)

GetConfigForClientFunc returns a function for tls.Config.GetConfigForClient

func GetServerCertificateFunc

func GetServerCertificateFunc(certFile, keyFile string) func(*tls.ClientHelloInfo) (*tls.Certificate, error)

GetServerCertificateFunc returns a function for tls.Config.GetCertificate

func LoadCAFile

func LoadCAFile(caFile string) (*x509.CertPool, error)

LoadCAFile reads and parses CA certificates from a file into a pool. The file must contain PEM encoded data.

func LoadKeyPair

func LoadKeyPair(certFile, keyFile string) (*tls.Certificate, error)

LoadKeyPair reads and parses a public/private key pair from a pair of files. The files must contain PEM encoded data.

func LoadPwdFile

func LoadPwdFile(passwordFile string) (map[string]string, error)

LoadPwdFile reads the redis password file and returns the password map
