This book is mostly minimal examples in whatever Python library the author decided to use. There are some major gaps. For example, the section on Python libraries doesn't even mention the most commonly used Python crypto library (crypt

The original statement I had disputed was "[Facebook has] the keys to decrypt [Secret Conversations messages]", which is false. If you think the contrary, then the evidence is in the client.

It's a falsifiable assumption. Audit the binaries if you want to convince yourself. You will see code to generate and use keys locally, with no mechanism to fetch or share keys from a server. If you want to go beyond generic concerns,

Your assertion is false. Please read the whitepaper. Facebook does not have the key to decrypt messages sent with Secret Conversations. It is generated on-device. You can confirm that using simple reverse engineering tools on, say, the Andr

Also, ZuccNet is using RSA-2048-OAEP to encrypt each message: https://github.com/tomquirk/zuccnet/blob/master/src/util/cry... This is not forward secure. It will also only work for messages und

Facebook Messenger already has Secret Conversations, which is end-to-end encrypted mode based on the Signal protocol. Here's the technical whitepaper: https://about.fb.com/wp-content/uploads/2016/07&#x2F

This is brilliant unintentional parody.

You are right. I was ill-informed. This is for green cards. My intent is opposite of nativist propaganda. I think the regulations are silly and companies are minimally complying with them.

I think you’re right. It’s for green cards and E visas.

OP here. Yes, Apple is certainly saving a bundle on classified ads in the free community paper with circulation of 6,000. These ads are just to go through the motions to get someone a visa. They don’t actually want anyone to reply to the ad

It not exactly a young research area. We have had post-quantum public key cryptosystems based on linear codes for over 40 years. Classic McEliece ( https://classic.mceliece.org ) was created in 1978 and is in the 2nd round of NIST

Before he even backdoored it, the lottery was using a Mersenne Twister? The random number is called the seed, and the seed is plugged into the algorithm, a pseudorandom number generator called the Mersenne Twister. At the end, the computer

Your friend is not going to get PhD thesis topics by asking his friend to post on HN. Regardless, here's what I think are interesting areas in recent crypto: - Performance improvements in fully homomorphic encryption, starting with Gen

Nobody uses anything related Wolfram's cellular automata. I don't think there are any robust security proofs.

I went to the library and checked out books with code you would type in by hand, like this one: https://en.wikipedia.org/wiki/BASIC_Computer_Games

I don't know if you've done it correctly. You can use the built-in signature digest support and still add support for whatever you want in the future.

Keyczar is no longer being maintained and should probably be deprecated. Either that or someone can take the reins and update it to use modern algorithms.

This sounds like something you could have proposed 15 years ago. It assumes local, custom email clients for "enabled-by-default encryption" and XMPP support. People have moved onto web and mobile email clients, and you can only us

I think Intel backed away from the documentation that implied all signed enclaves had to go through them. I think people can attest their own SGX enclaves.
