Before issuing a certificate to a customer, DigiCert validates the customer’s control or ownership over the domain name for which they are requesting a certificate using one of several methods approved by the CA/Browser…
Among the cryptographic missteps we see at Trail of Bits, “let’s build our own tool out of a hash function” is one of the most common. Clients have a problem along the lines of “we need to hash a bunch of different values together” or “we need a MAC” or “we need […]

A post by Eshel Yaron with details and advice about a long standing arbitrary code execution vulnerability in Emacs
When it comes to designing secure protocols, I have a principle that goes like this: if you have to perform any cryptographic operation before verifying the MAC on a message you’ve received, it will somehow inevitably lead to doom.
The Consumer Finance Protection Bureau (CFPB) has just finalized a rule that makes it easy and safe for you to figure out which bank will give you the best deal and switch to that bank, with just a couple of clicks. We love this kind of thing: the coolest thing about a digital world is how easy it...
