Functions

func CryptoString

func CryptoString(n int) (string, error)

CryptoString 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. This should be used when there are concerns about security and need something cryptographically secure.

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.
