Fair warning: I'm not a cryptographer or any sort of expert in security. Use at your own risk.

Installation

go get github.com/jlpellicer/xkcdpass

Usage

import "github.com/jlpellicer/xkcdpass"

config := xkcdpass.Config{
	MinLength: 12,
	MaxLength: 18,
	Language:  "es",
	Separator: ".",
	Numbers:   3,
}

password, err := xkcdpass.Generate(config)

if err != nil {
	log.Printf("Error: %s", err)
}

log.Printf("Password: %s", password)

Notes

xkcdpass will try it's best to give you a password based on your parameters.

MinLength: a minimum possible length will be calculated, based on the language file of your choice and an error will be returned if MinLength is less than the shortest word in the file
MaxLength: also, if MaxLength is less than the shortest word, an error will be returned (ok, fringe case, but, hey, one tries to be thorough)
Language: currently English (en) and Spanish (es) are supported. You can add your own %s_words.txt to static and if you would like to add your language to this repo then send me a PR. These lists have been curated to contain mostly words that are reasonably less common to be used in each language. If you want to compile a list of words for your language, try to find a source that can help you apply the same kind of filter and keep a high number of words
Separator: can be any string you want, probably best to keep it to one character, such as a period, dash, space or none (use an empty string or leave it out)
Numbers: add an amount of random numbers to the end of word list
