feature : Stronger Encryption Algorithm for Passwords

[vedanthv]

Is your feature request related to a problem? Please describe.
Yes it is related to a problem. In #38 I have used bcrypt for password encryption with salt = 10. We can improve the security using other encryption techniques.

Additional context
Check out the code in #38. You can find the hashing code in user.model.js. Here is the link to the JS script.

Specifications
Algorithm design and implementation in JS is preferred instead of Python. If you manage to do it in Python create a PR and link it to this issue. I will refactor in JS.

Action Items

• Reference and Review Material to save some time : Auth0 Blog Storagecraft Blog
• Draft a README with a short explanation of how the algorithm is better than bcrypt.
• Implement the algorithm in JS(preferred). If written in Python, please include clear and concise comments!
• Algorithm Implemented in Python[Optional] click convert to issue if you do this ----->
