Functions

func FastXor

func FastXor(dst, a, b []byte)

Xor 16 bytes the fastest way

From https://github.com/lukechampine/fastxor Stores (a xor b) in dst, where a, b, and dst all have length 16.

func GetConn

func GetConn(network, address, certFile, keyFile string) (net.Conn, error)

Get a connection with/without TLS

TODO: remove InsecureSkipVerify from tls.Config

func GetListener

func GetListener(network, address, certFile, keyFile string) (net.Listener, error)

func GetName

func GetName(id []byte) string

Returns base64url encoding of id

Used for block filename

func GetNumber

func GetNumber(id []byte) uint64

Returns big endian uint64 of id

func HashStr

func HashStr(val string) []byte

Uses Go's built-in fast hash func FNV version 128a

func RandomId

func RandomId() ([]byte, error)

func SlowXor

func SlowXor(dst, a, b []byte)

For benchmark comparison
