A demo client to illustrate encryption, decryption and hashing functions with AES, SHA2 and RSA.

IMPORTANT DISCLAIMER!! This is not a secure application, or a secure or recommended way of encrypting data, it's a simple demo to illustrate the principles only. Do not use this a secure encryption example / reference code for a secure system in any way. Please refer to the numerous articles and info on encryption and security on the interwebs for that!

• /public = CSS (stylesheet)
• /views = ejs based index.html page
• /controllers = controller code with HTTP UI rendering and encryption code
• app.js main app code

• encrypt plaintext to cipher using password/secret (AES)
• decrypt cipher to plaintext using password/secret (AES)
• hash plaintext, using an optional password/secret (SHA-2)
• rsa key generation create private and public keys
• rsa encryption using public key
• rsa decryption using private key
