Simple NodeJS Backend Script Designed To Calculate & Manage Hashes

I need a good and cheap back-end developer with beginner-level or even better, mid-level NodeJs back-end dev skills to build me a script that I need for a bigger project ( I am trying to build a cool set of tools like [login to view URL] all related in different ways to generating passwords and how those passwords work ) and among those tools I need a simple api system calculate and manage Sha256 hashes and show if a string like a potential password already exists in the system to show somehow how weak that password is.

The backend needs to be something in NodeJs that acts like web service that has two end-points:

1. /messages takes a message (a string) as a POST and returns the SHA256 hash digest of that message (in an easy to digest format like the hex format)

2. /messages/< hash > is a GET request that returns the original message. A request to a non-existent should return a 404 error.

To sum-up, if you hit the api point with http://localhost/messages/XYZ ,

the api should respond for a message like

XYZ = 2c26b46b68ffc68ff99b453c1d30413413422d706483bfa0f98a5e886266e7ae

with { message: “foo” }

else you can just hit the api messages/ with your own string with something like a POST hidden method instead of get meaning if you hit with post your own post data it should reply with the hash.

Ideally the database should be in something like MongoDB and if you can find a service where I can host this DB for free that would be even better.

I am willing to pay a separate milestone if you can do another script for another type of hash algorithm like MD5 and another one for SHA1, maybe.

Project is not that urgent but I don’t wanna wait forever either…

I will provide more info if needed.


Note: No unit-testing script needed or anything over-complicated.

Note2: You can use your own [login to view URL] account or I can give you my account or if you know any other similar platforms do let me know as long as we are talking about a fee db platform.
