imranansari / go-password

A Golang library for generating high-entropy random passwords similar to 1Password or LastPass.

Golang Password Generator

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.
