Security Audit

[ulissesferreira]

It is important for us to keep our data safe. We need to make sure we are not vulnerable to any of the following attacks. Add some more for our audit.

• SQL Injection (do we escape all char entrances? the API only accepts requests from connect.upframe.io and beta.upframe.io but this can be easily spoofed...)
• Brute forcing (add timers)
• Are hashes complex enough? (make sure we are up to date in the difficulty stage. Our hashing algo is safe, but our steps are a little low I believe)
