# gonss3

Package documentation: https://godoc.org/github.com/rusq/gonss3

Package gonss implements the subset of Mozilla NSS3 library. It implements

just enough to decrypt the firefox profile passwords.

I take no credit, implementation is entirely based on [this project][4] which

is based on [Dr Stephen Henson research for "Netscape Key Databases"][1].

Supports only `key4.db` (sqlite).

This library is created for educational purposes and licenced under LGPL 3.0.

## Usage

```go

package main

import "github.com/rusq/gonss3"

func main() {

  profile, err := gonss3.New("/path/to/profile", []byte("masterpass"))

  // handle err

  userCt, passCt := // fetch some data from logins.json

  user,err := profile.DecryptField(userCt)

  // handle err

  pass,err := profile.DecryptField(passCt)

  // handle err

  fmt.Println(user, pass)

}

```
