Overview

Package hash contains different hash algorithms and utilities

Index

• func FileHash(file string) string
• func JCHash(key uint64, buckets int) int

Examples

• FileHash
• JCHash

Functions

func FileHash

func FileHash(file string) string

FileHash generates an SHA-256 hash for a given file

Example

hash := FileHash("/path/to/some/file")

fmt.Println(hash)

func JCHash

func JCHash(key uint64, buckets int) int

JCHash generates Google's Jump Consistent Hash More info: http://arxiv.org/abs/1406.2294

Example

var (
	key     uint64 = 0xDEADBEEF
	buckets int    = 128 * 1024
)

hash := JCHash(key, buckets)

fmt.Println(hash)
