Functions

func Fnv

func Fnv(data string) string

Fnv is a non-cryptographic hashing function based on non-cryptographic hash functions created by Glenn Fowler, Landon Curt Noll, and Phong Vo. This wraps the standard library FNV hash function by representing it as a 32 bit integer. Then it takes that number and "hashes" it by adding the rune's unicode value (as a uint 32) and then takes the modulus of 26, letting the number be represented as a letter of the alphabet. This is not a cryptographically secure operation, it is purely to replace numbers with a human-readable string to satisfy the requirement that any vhost with a "/" in it cannot end in a number (to avoid someone obtaining a vhost that is a cidr mask, it can cause issues).

func Hash

func Hash(data string, salt string) string

Hash is a simple wrapper around the MD5 algorithm implementation in the Go standard library. It takes in data and a salt and returns the hashed representation.
