This might be crazy but here is what I would like to do.

have a text box that I can type plaintext into, click a button which then calls for Actionscript to apply an encryption algorithm to each letter in the textbox and then return the ciphertext to a second textbox....then be able to decrypt the ciphertext back to plaintext.

The important part would be having access to each letter individually in order to apply the encryption.

The encryption would be written in the AS editor.

Just for fun, nothing important.

Anyone got any ideas?
