Use public/private keys for data encryption?

[Niami 0]

I'm not sure if this is possible as the encrypt function can only use an AES key. Are there any other methods that use the public/pricate key from the generateKeyPairs function?

You should look to the docs. I'm not versed in pub/priv key pairs but I imagine the decrypt function takes either key(but usually the private?) to decrypt encrypted data

@Niami Here is a link https://ocdoc.cil.li/component:data

Basically it works like this: user A and B both generate a key pair. Then they exchange their public keys. Then the actual AES encryption key is calculated from own private and other users public key these calculations end up in the same result. In other words: A public + B private = B public + A private. Thus allowing encryption and decryption. 

This is explained in the docs, but poorly.

I may have some examples,I might share if you're interested.

@SpaceBeeGaming If you could share those examples that would be great as when I try to do this the ecdh() function generates a string that is larger than 16 characters and keeps the AES encryption from working.

I'm a wee bit late to the show, but for future reference for anyone googling this issue, If you take the combined key you get from the Diffie-Hellman function and run it through the md5 function it comes out as a 128 bit binary. it is really odd that the key generator makes keys that are too long for the only real encryption program that came with it. There's also a set of libraries and programs available on open programs, called lua-lockbox, that have a whole heap of different encoding and encrypting files and functions, though i haven't tried them myself, so i'm unsure if they still work

lua-lockbox should work. There's also Pure Lua Crypto, which I use (it's a bit smaller).
