Functions

func Hash

func Hash(salt, input string) string

Hash returns a secure hash of the provided input. If a salt is provided, the input is prepended with the salt prior to hashing.

func NewToken

func NewToken(tokenLength int) string

NewToken returns a new, unique, hard-to-guess token consisting of alphanumeric characters only. The token's length is the greater of 64 or the length specified. i.e. This function produces tokens with a minimum length of 64 characters. The generated tokens incorporate a UUID (v4) to ensure uniqueness. This minimum token length of 64 was selected so that any given token consists of at least as many random, hard-to-guess characters is it does more deterministic characters.
