I'm making a “safe” chatroom, but I need to know how to encode/decode, any help?

I haven't looked at any other projects that do this, so there may be superior solutions, but I thought it was an interesting challenge, so I whipped up an encoder:

http://scratch.mit.edu/projects/11748261


The notes in the project mostly explain how it works. Let me know if you have any questions.

(I didn't include the decoder. For that, you would take the encoded text, split it up into 2-digit bundles, and look up the that item number on the encoding list.)

thanks @fleurymarc for the decoder!
I'm going to use it in one of my programs,
but should I call you fleurymarc or Mark in the credits section of the page?

check here http://scratch.mit.edu/projects/23616013/#player for a fast encoder that can encode a whole 70 item long list in 1.14 seconds

My encoder is https://scratch.mit.edu/projects/51262342/. Hope you like it!

If you're using a white list of words or phrases you don't actually need to encode or decode text - just put the item number of the list in a cloud variable using a fixed-length number. So if you have less than 100 words and phrases each can be added to the cloud variable as two digits.

So ‘230956’ would convert to item 23 from the list, followed by item 09 followed by item 56.

This will use fewer digits in the cloud variable and be quicker than encoding/decoding individual text characters.

JacobyJr, your encoder isn't shared.
