When you download an aaxc book with `audible-cli` the voucher file is automatically downloaded. Or do you want the voucher file only?

Aaxc files make use of a key/iv pair to decrypt the book. The key/iv pair is responded with a [licenserequest](https://audible.readthedocs.io/en/latest/misc/external_api.html#post--1.0-content-(string-asin)-licenserequest). But the key/iv pair is encrypted. For decrypting the key/iv...

@M05QU170 If you use `audible-cli` you have to replace: 1. {voucher.content_license.license_response.key} with the `key` value from the voucher file. 2. {voucher.content_license.license_response.iv} with the `iv` value from the voucher file 3....

> Just quick question why there is chapter intergration work going on? If converting from aax/aaxc to m4b all it needs to pass "-c copy" flag to ffmpeg. If you...

Thank you for your PR. I have this already changed in the dev branch. This will be released with the next version.

@philgoetz Thanks for the information. This reminds me of issue #66. These file are created by a GitHub action using pyinstaller.

The metadata are written back using `utf-8`. Maybe this is the wrong encoding. I'll check these and report back. FYI: The metadata extracted using ffmpeg does not contain the full...

Hi @snowskeleton. Very good work. I'll take a deeper look on your project. Do you have some speed comparison against ffmpeg or [AAXClean](https://github.com/Mbucari/AAXClean)?

> On another other note, if nothing else, you could steal the key derivation so you can use the same methods for decrypting aax vs aaxc. What do you mean...

@snowskeleton Sorry for my late reply. I'll take a look at your project now. Can you tell me how long it takes to compute the key/iv from the activation bytes?
