I found this article and liked it because it gave me a lot of information about the Beale Cipher and treasure, even more information than Singh. I especially was interested in the reasons describing the possibility of it being real or a hoax.

This blog has information about military cryptography and privacy in general, including this post about the Zimmermann Telegram. Is it ethical to lie to an ally if it is in their best interest? What are the ethics behind spying on one's allies? Do ethics hinder one's ability to win a war, and if so, should ethics be disregarded in times of war? Another interesting post examines how Snowden should be viewed as a patriot, not a traitor. This made me question where one's loyalty should remain- to the government or to the people?

This article describes how, during the Cold War, the major distributor of cryptography machines (Crypto AG) worked with the NSA. This professional relationship provided the NSA with shortcuts on how to break ciphers created from the different machines. Also, Crypto AG was revealed as not having given the most up to date models to all countries, probably through deception. This raises the question of morality involving basic warfare. How is it moral for this supposedly trusted third party company to have special allegiances with the United States?Would the United States have the same opinion on this actions morality if they were the ones being sold out of date equipment? Or if one of their opponents had shortcuts?

Example of how improving technology requires new encryption that hasn't yet been cracked

Hidden messages? Check. Cheating? Check. Seems on-topic for this course!

Interesting article that shows how even though we think we're very advanced at cryptography, sometimes an old and outdated technique slips through the cracks in our defenses.

Non-U.S. users frequently encounter the annoyance of geo-blocked content when trying to access popular sites like Hulu, but every now and then we feel the burn in the States, too. Reader hengehog details how to access BBC's iPlayer from outside the U.K.

Interesting that ~35% of 1000 surveyed have upped the strength of their passwords, but only 6% turned on two-factor ID, which was a major cause of the iCloud hacks going undetected for so long.

It seems that two-factor authentication would not have prevented those iCloud hacks (according to this piece: http://www.tuaw.com/2014/09/02/think-iclouds-two-factor-authentication-protects-your-privacy/), but since Apple has now changed the triggers for two-factor to include things like iCloud access, two-factor will be more helpful going forward. So it is a little surprising that more people haven't enabled it.

I'm also reminded of the ACLU's Chris Soghoian's point (https://www.aclu.org/blog/technology-and-liberty/lessons-celebrity-icloud-photo-breach) that one reason people have crappy Apple passwords is that Apple makes you use your password so darn often. I know I get frustrated when I have to enter my (crazy long) Apple password on my iPhone just to download a free app.

This is a website introducing codes and ciphers in WW II by Tony Sale. Given this specific war context, is there really a guideline of what an action is ethical and what is not in terms of cryptoanalysis? Would an action be ethical whenever the majority's well-being is satisfied, or there's a line that should not be crossed?
