Encrypt in mysql, decrypt in javascript
View README.md

What is this?

A way to encrypt data on mysql and then decrypt in javascript.

Why is this useful?

Sometimes you have data in your mysql database and you want to pass this data to a JS app.
For example, say you want to run an email campaign and you want to send emails to users from your mysql database. In this campaign you want ppl to click a link and when clicked you want the target site (your site) to be able to identify the user. You could pass the user-id as plaintext. Or the email as plain text. But that would be insulting the user's intelligence plus you might leak information "in the face" of a user. If you want to pass information from mysql to javascript and be able to obfuscate this info such that it isn't in the face of a user, this method is simple and effective.

This is not "secure"
