Golang Password Generator
This is a fork of the sethvargo/go-password repository, which has made changes that, in my opinion, make the library safer and easier to use. But since the main developer did not accept these changes, so as not to break the established API, I created this fork.
This library implements generation of random passwords with provided requirements as described by AgileBits 1Password in pure Golang. The algorithm is commonly used when generating website passwords.
The library uses crypto/rand for added randomness.
Sample example passwords this library may generate:
0N[k9PhDqmmfaO`p_XHjVv`HTq|zsH4XiH8umjg9JAGJ#\Qm6lZ,28XF4{X?3sHj
7@90|0H7!4p\,c<!32:)0.9N

Since these are completely randomized, it's possible that they may generate passwords that don't comply with some custom password policies, such as ones that require both upper case AND lower case letters. If your particular use case needs a mix of casing, then you can either increase the number of characters in the password or check the output and regenerate if it fails a particular constraint, such as requiring both upper and lower case.
Installation
$ go get -u github.com/juev/go-password/password
Usage
package main
import (
"log"
"github.com/juev/go-password/password"
)
func main() {
// Generate a password that is 64 characters long with 10 digits, 10 symbols,
// allowing upper and lower case letters, disallowing repeat characters.
res, err := password.Generate(password.Input{
Length: 64,
Digits: 10,
Symbols: 10,
})
if err != nil {
log.Fatal(err)
}
log.Printf(res)
}
