crypt provides pure golang implementations of UNIX's crypt(3).

The goal of crypt is to bring a library of many common and popular password hashing algorithms to Go and to provide a simple and consistent interface to each of them. As every hashing method is implemented in pure Go, this library should be as portable as Go itself.

All hashing methods come with a test suite which verifies their operation against itself as well as the output of other password hashing implementations to ensure compatibility with them.

I hope you find this library to be useful and easy to use!

To install crypt, use the go get command.

go get github.com/GehirnInc/crypt

package main

import (
    "fmt"

    "github.com/GehirnInc/crypt"
    _ "github.com/GehirnInc/crypt/sha256_crypt"
)

func main() {
    crypt := crypt.SHA256.New()
    ret, _ := crypt.Generate([]byte("secret"), []byte("$5$salt"))
    fmt.Println(ret)

    err := crypt.Verify(ret, []byte("secret"))
    fmt.Println(err)

    // Output:
    // $5$salt$kpa26zwgX83BPSR8d7w93OIXbFt/d3UOTZaAu5vsTM6
    // <nil>
}
