README

password-bcrypt-service

Overview

The service uses the bcrypt algorithm to encrypt an incoming password to a hash string. As bcrypt may be computationally expensive, the service uses the pool of workers to do the job. If there are too many incoming requests and all workers are busy more than given BusyTimeout, the service returns 429 status Too Many Requests.

• /bcrypt - use the POST method and x-www-form-urlencoded parameter password. Returns bcrypt encrypted password.
