encryption?

I'm not sure if the Espruino can support encryption features.... If I had to guess, Espruino probably can't due to resources needed to encrypt data.

If that is the case, does anyone know of a way to encrypt data before sending the data out of the Espruino; eventually gets sent out of my WiFi module to a TCP server? I found https://www.sparkfun.com/products/11551 which is a way to securely store a key.

At the moment I am sending out unencrypted text such as login credentials that should be encrypted on the Espruino side then unencrypted at the server side.

You may use crypto-js (i didn't test it personally but should work) and there are tons of JavaScript implementation of the cryptographic algorithms out there on the net.

if your only concern is username/password, hash the password (with a seed) and send it to server. I think sha1 is the smallest/lightest hashing implementation.

Or if you want to spend less memory and have less security, check this XOR String Example, I just wrote for you.

@Kay, Thanks! I greatly appreciate you taking the time to create XOR.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

```

Just like Github, a blank line must precede a code block.
