Text Steganography - Encrypt/Hide text using JavaScript and Decrypt/Unhide
using PHP

I've googled a lot about steganography for text and found this:
http://www.fourmilab.ch/javascrypt/javascrypt.html &
http://www.fourmilab.ch/javascrypt/stego.html
The basic fundamental of these url is to convert any text into encrypted
code & then using second url convert that encrypted code into NON SENSE
english words with punctuation.
This is done using javascript and it works perfect. My half work is done
here.
Now I'll be sending this NON SENSE english words, with punctuations, to my
server using form. I don't know how to decrypt the data at server end
using PHP because it is converted via JavaScript.
I don't want the data which is transferred via network to be read by
anyone. I want only english words to be transferred via network, nothing
else.
Do you know anything similar to this? Steganograph the form (only to
English Words with punctuations) before sending using JS/JQuery and decode
using PHP.
Or can anybody suggest how to make the server side part working from the
above links.??
Any help is welcomed.
Thanks
