re-encryption

i am trying to figure out a way to re-encrypt a decrypted epub file ... if any have gone through the process of decrypting there epub files with ignobleepub and python, they might have discovered that the encryption.xml and key.xml files are stripped from the epub ... which, of course, is the point ... but, if you were decrypting epubs (interactive / javascript epubs like The Elephants Child) for the purpose of education to understand how the epub was compiled ... and having done so (comprehended how it was constructed) you may want to create your own ... for the purpose of testing ... and, then, may discover that not only does your NookColor have an internal manifest file, but it will NOT accept an unencrypted interactive epub. Has anybody found a relatively easy way of re-encrypting the decrypted files using the encryption key created by ignoblekey generator?

A good rule to follow is to always backup/copy the original files before decrypting, and only decrypt the copy. Depending on where you bought the ePub, you might be able to re-download it. Most ePub stores allow you to re-download the books you purchased.
