Silent Circle: NIST encryption standards untrustworthy

The National Security Agency's apparent attempts to weaken encryption technology has led a private-communication startup to move away from encryption algorithms from the US government's National Institute of Standards and Technology.

Silent Circle co-founder Jon Callas called NIST encryption experts "victims of the NSA's perfidy" in a blog post Monday and said the company will move away from using encryption standards that NIST helped create. The standards will still be available, but not by default, he said.

"At Silent Circle, we've been deciding what to do about the whole grand issue of whether … Read more

How NSA snooping secures profits for famed privacy pro (Q&A)

In a double dose of irony, the National Security Agency's prying has given a big helping hand to Phil Zimmermann's business, Silent Circle.

The first irony is that Zimmermann was the very person the US federal government fought with in the 1990s over the release of the software called PGP, short for Pretty Good Privacy, which made encryption much easier to use. The second irony is that he's now president and co-founder of Silent Circle, a company that seeks to profit from making it harder for the NSA or anybody else to find out what people are … Read more

Phil Zimmermann's post-PGP project: privacy for a price

He rocketed to privacy stardom over two decades ago with the release of PGP, the first widely available program that made it easy to encrypt e-mail. Now Phil Zimmermann wants to do the same thing for phone calls.

Zimmermann's new company, Silent Circle, plans to release a beta version of an iPhone and Android app in late July that encrypts phone calls and other communications. A final version is scheduled to follow in late September.

This time around, Zimmermann is facing not the possibility of prison time on charges of violating encryption export laws, but a more traditional challenge: … Read more

PGP Desktop disks not mounting after OS X 10.7.4 update

Some users of Symantec's PGP Desktop encryption software are finding that after installing OS X 10.7.4, the program does not appear to respond properly and encrypted disks can no longer be accessed.

Judge: Americans can be forced to decrypt their laptops

American citizens can be ordered to decrypt their PGP-scrambled hard drives for police to peruse for incriminating files, a federal judge in Colorado ruled today in what could become a precedent-setting case.

Judge Robert Blackburn ordered a Peyton, Colo., woman to decrypt the hard drive of a Toshiba laptop computer no later than February 21--or face the consequences including contempt of court.

Blackburn, a George W. Bush appointee, ruled that the Fifth Amendment posed no barrier to his decryption order. The Fifth Amendment says that nobody may be "compelled in any criminal case to be a witness against himself,&… Read more

Encrypt your e-mail with Enigmail

An extension for Thunderbird and SeaMonkey, Enigmail is a must-use for anybody who's concerned about sending e-mail that can be read by anybody, including your Internet Service Provider. It's not intended to encrypt all of your mail, although you can certainly do that. Rather, it's best used for ensuring that even remotely sensitive e-mails don't get read by the wrong person.
