+1 to the hatedpatriot for posting an excellent article.For the "tldr" crowd, this has to do with potential weaknesses in the RSA cryptosystem which underpins the security of PGP messages, as well as Onion routing and even the Bitcoin network itself.Before we begin weeping into our cereal just yet I would like to make an observation, in that while I know only a small amount about cryptography but it's clear even to me that if one of the many mathematical experts in the world (not all of whom live in the USA!) were to discover a fundamental flaw in RSA, using the resources of one of the well funded mathematical institutions around the world, then they would instantly have fame and wealth beyond measure so this begs the question, if this has weakness has been rediscovered, why hasn't anyone else mentioned it? It is certainly a very hot topic in Cryptographic circles.Let's assume however that the flaw is either very obscure or that the FBI has somehow managed to convince every other major government / academic institution to keep its discovery quiet. This is not unthinkable - the British government hushed up their cracking of the Nazi enigma code after the war and redistributed captured Enigma machines amongst their former colonies as supposed gifts - they merrily cracked their confidential messages for decades afterwards!You have probably seen already the dilemma here - indeed it was one the British faced during the war which was that in acting upon information received they could accidentally reveal they had broken what the Germans believed was an unbreakable form of encryption and force the Nazis to use a more advanced way to code the messages. The FBI would be faced with the same dilemma - by decrypting your e-mail revealing your address to receive drugs for instance would be tantamount to revealing their hand. Do you really think they're going to do this for the sake of the miniscule amounts of narcotics on SR or would you simply not act on any correspondence unless the security of your country was at stake?The point is also moot for those of us outside the USA in any case. I know for certain that the Police in the UK cannot crack RSA encryption having being used as a consultant during two investigations. Both times the investigating officers frankly admitted they couldn't break open correspondence protected in this way any more than they could AES encrypted file containers. For this reason, British Police have resorted to RIPA (Regulation of Investigatory Powers Act) which empowers them to insist individuals reveal their passwords or be faced with up to two year's imprisonment.All in all with PGP I'd say you are PDS (Pretty Damn Safe).V.
