I have never seen security and privacy checklists used for any other purpose but deception. After pondering this observation, I’m left seriously doubting if comparison checklists have any val…| Dhole Moments

I’ve been reading up on the Double Ratchet algorithm and its implementations lately, as it’s an exciting piece of crypto that offers some very nice guarantees: forward secrecy (ie. by breaking a key at some point you can’t read older messages), eventual break-in recovery (ie. by breaking a key you can only read a few messages before the protocol recovers), and of course confidentiality and deniability. It’s all done through the use of “ratchets”, which are used to update the key u...| nikofil's blog
Threema boldly claims to be more secure than Signal. Does this hold up to scrutiny?| Dhole Moments

This article discusses several open-source implementations of the HKDF scheme for Android. Since HKDF is a relatively simple algorithm, it allows for a good case study of cryptographic code. The primary audience are applied cryptographers and software engineers working on protocols. Key derivation functions (KDFs) are an important building block for practical protocols. They take as input the input keying material (IKM), an optional salt, and a context string (info). Their output is a pseudor...| Daniel Hugenroth

The Signal Protocol is a set of cryptographic specifications that provides end-to-end encryption for private communications exchanged daily by billions of people around the world. After its publication in 2013, the Signal Protocol was adopted not only by Signal but well beyond. Technical informat...| Signal Messenger
