Tin Foil Hat Show - Episode 001


Well to answer popular demands I am proud to announce my debut podcast episode on the Fuzion Podcast Network. This is my podcast where I will soap-box about digital human rights, personal security and the online age.

The intro show is the only one posted at the moment, and I won't say too much except to ask you all to be patient and give me a few shows to let it settle out.

I look forward to your feedback, you can send feedback for the show to tinfoilhatshow@gmail.com or you can contact me by any of the other methods listed here on this blog.

In the show I mention that there would be a couple of commands shared on this post. So in closing, I just want to say to use the following commands to get at the show notes. The number on the text file should change with each episodes, but it will be the only mystery text file in the directory after the other two commands.


eyeD3 --write-image=./ $Filename.mp3
steghide extract -sf FRONT_COVER.jpeg
less tfh-00X.txt

Enjoy and please do send me feedback and corrections, it can only make the show better. A permanent link to the show's rss feed is listed on the right side of the blog.

-----------------------UPDATE----------------------------

It seems that the mp3 file has ID3 tags processed during the workflow to get it in the feed. During these steps the original image becomes corrupted. Here is the original JPEG and I'll work with the production folks to make sure the original mp3 file gets fixed. Sorry for the problems with the commands, I hope that will work correctly in future episodes.

Where can I find the Podcast RSS-Feed for my podcatcher?

On http://www.fuzionpodcastnetwork.com/ I couldn't find the right feed. There are no media files included in the Tin Foil Hat Show Category Feed)

After I run this command
$ eyed3 --write-image=./ TFH-001.mp3
eyeD3 writes the file OTHER.jpeg

When I try to run
$ steghide extract -sf OTHER.jpeg
i couldn't manage to get the text file. steghide don't accept my passwords. I tried "tinfoilhat", "TinFoilHat", "Tin Foil Hat", "tin foil hat", "tinfoilhatshow" and "TinFoilHatShow"

But steghide print the following message:
steghide: could not extract any data with that passphrase!

What's wrong here?

Could be the file got corrupted. I'm pulling it down from the feed to replicate the experience you had. I'll try to run the commands and discover what might have happened.


I'll be back to update very shortly.

Well, I have tested and confirmed there is a problem with the file. The checksum on the image before and after is different. I will make an update post to the main blog post to add the original image. Please pull that down and run the steghide command. You had it correct with "tinfoilhat" and I'll double check, but I think there is a ID3 process that happens to my MP3 file that seems to have corrupted the file.

Thanks for reporting that to me, I'll post the original image for Episode 2 since it is already in the feed and try to get the tag issue resolved.

For me, I had to type in eyeD3, that is, with a capital D, for it to work.

Below is a simple bash script to get the notes. The passphrase I used is 'tinfoilhat'.

#!/bin/sh

EPISODE=`echo "$1" | cut -f1 -d.`

eyeD3 --write-image=./ $1

steghide extract -f -p 'tinfoilhat' -sf FRONT_COVER.jpeg -xf "$EPISODE"_notes.txt
