Functions

func B2S

func B2S(b []byte) string

b2s converts byte slice to a string without memory allocation. See https://groups.google.com/forum/#!msg/Golang-Nuts/ENgbUzYvCuU/90yGx7GUAgAJ .

Note it may break if string and/or slice header will change in the future go versions.

func GenerateRandomBytes

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

GenerateRandomBytes returns securely generated random bytes. It will return an error if the system's secure random number generator fails to function correctly, in which case the caller should not continue.

func GenerateRandomString

func GenerateRandomString(s int) (string, error)

GenerateRandomString returns a URL-safe, base64 encoded securely generated random string. It will return an error if the system's secure random number generator fails to function correctly, in which case the caller should not continue.
