Command line tools and library to work with hashes and various encodings

About

Command line tools and library to work with hashes and various encodings.

Compatibility: All platforms supported by go, notably Linux, macOS and Windows.

Commands

coder encode / decode pipes or files between various encodings

hasher calculate hashes from stdin or files

findhash search for plaintext matching known hashes

Install everything

See Releases for binary packages for macOS and Windows. To compile from source with the go toolchain:

go get -u github.com/martinlindhe/gohash/...

Library example

import "github.com/martinlindhe/gohash"

func ExampleNewCalculator() {
	r := strings.NewReader("hello world")
	calc := NewCalculator(r)
	h, _ := calc.Sum("sha1")
	fmt.Printf("%x", h)
	// Output: 2aae6c35c94fcfb415dbe95f408b9ce91ee846ed
}
