Secure Token and FileVault on Apple File System | Der Flounder
As part of Apple File System’s FileVault encryption on mac OS High Sierra, Apple introduced Secure Token. This is a new and undocumented account attribute, which is now required to be added to a user account before that account can be enabled for FileVault on an encrypted Apple File System (APFS) volume. To help make sure that at least one account has a Secure Token attribute associated with it, a Secure Token attribute is automatically added to the first account to log into the OS loginwindow on a particular Mac.

Police Just Found Phone & USB Stick Belonging To Paris Suicide Bomber, After Misplacing It For Almost Two Years | Techdirt
Remember how, right after the Paris bombings, people started blaming encryption for the attacks, despite the fact it was later revealed that most of the planning was done in the open and communication occurred via unencrypted SMS messages? As we noted, it seemed pretty clear that the bombings were an intelligence and law enforcement failure rather than an encryption problem.

Now, just to add more evidence to that conclusion in the most ridiculous way possible, apparently Brussels police just found a mobile phone and USB stick that had belonged to one of the suicide bombers in the Paris attacks, Brahim Abdeslam. The police had seized the phone and USB stick during a drug raid back in February of 2015... and promptly misplaced them entirely. They were found under a stack of papers.

The Cryptopals Crypto Challenges
Quick plug: set 8 is out. It's all about attacks on elliptic curves and GCM.

This set is huge. There's as much content as in any two or three other sets.

This set is tough. It's easily the toughest set so far. And there is some math. But it's fascinating stuff and (I hope) pretty approachable.

This set is OG cryptopals. That means we're (for now) distributing it via email. If you want to check it out, send a mail to with subject "Crazy Flamboyant for the Rap Enjoyment"

French, German ministers demand new encryption backdoor law • The Register
In the lead-up to the meeting and in subsequent public comments from the ministers, they both made repeated mention of the issue of data encryption, even calling out the app Telegram as an example of a problem they wish to find a solution to.
French interior minister Bernard Cazeneuve even went so far as to argue that the European Commission (EC) should draft a new law that would require companies to work with the authorities to decrypt secure communications on demand and help track down terrorist suspects.

This proposed law would "impose obligations on operators who show themselves to be non-cooperative, in particular when it comes to withdrawing illegal content or decrypting messages as part of an investigation," Cazeneuve said to reporters.

Predictably, those remarks have led to concerns that the European Union will pass new legislation that would effectively ban secure end-to-end-encryption, and hence outlaw the use of apps such as Whatsapp and Telegram.

French & German interior ministers call on EU to enable access to encrypted data
In a joint press conference in Paris on Tuesday, the interior ministers of France and Germany called on the European Commission to enact laws that would give countries on-demand access to encrypted communications under some circumstances.
Exchanges via some apps "must be able, as part of court proceedings — and I stress this — to be identified and used as evidence by the investigation and magistrates services," said France's Bernard Cazeneuve, according to TechCrunch. […]
Cazeneuve and his counterpart, Thomas de Maizière, would like the European Commission to have laws enforcing the same rights and obligations for internet services and telecoms operators across Europe, even if they're not headquartered in the European Union. The ministers want their proposals discussed at a September Commission meeting.
