cself

PkgGoDev Build Status

Fork of checksum.

Computes checksum (such as SHA256) from files or stdin in Go. Uses chunking to support large files.

Computes key from KDFs (such as Argon2id) with either given parameters or sane defaults.

Usage

binary
§ cself -h
NAME:
   cself - generate hashes for files, passwords, and stdin

USAGE:

COMMANDS:
   list-alg, l  list algorithms
   hash, h      hash mode
   kdf, h       hash mode

GLOBAL OPTIONS:

library
package main

import (
	"fmt"
	"git.gryffyn.io/gryffyn/cself/checksum"
)

func main() {
	file := "~/Downloads/ubuntu-gnome-16.04-desktop-amd64.iso"
	md5, _ := checksum.MD5sum(file)
	fmt.Println(md5)
	sha256, _ := checksum.SHA2sum(file, 256)
	fmt.Println(sha256)
