⏰LAST CHANCE to fix #BillC22! It threatens 🇨🇦’ rights, #encryption, and privacy!

Tell senators to reform it: https://openmedia.org/ReformC22-mtd

The bill will require digital services to retain metadata for 6 months and enable secret orders forcing apps, messaging services, and others to build backdoors!

THIS WEEKEND! Lockdown Systems will be at HOPE 26! 🌐🐢

Our collective member @redshiftzero will be giving a talk about post-quantum encryption and where we are in the post-quantum transition!

The arrival of a cryptographically relevant quantum computer means that encrypted data collected now could be at risk of getting decrypted later. This is why we need to prepare now! 🔒️

Harvest Now, Decrypt Later

When: Sunday, August 16th at 10am
Where: New York City (USA), New Yorker Hotel, Gramercy Park Suite

The Register: Signal adds an extra layer of security to make sure you’re actually chatting with the right person. “Signal has introduced a new layer of security to help make sure no one has secretly interfered with your encrypted chats. The chat app is favored by diplomats, activists, and journalists for its security. It uses end-to-end message encryption and ‘safety numbers’ – cryptographic […]

For people like me who are obsessed with details, the blog post is a long and fun read.

Not that it is in any corporates' interest to allow their customers to encrypt communications entirely, but signal's work on encryption is worthy to be a product of its own.

The 12 words that lock Catchlight are called a Privacy phrase, not a seed phrase, and that was deliberate.

Seed phrase carries crypto baggage and puts the emphasis in the wrong place. It sounds like a recovery afterthought you jot down once and forget.

Those words are the whole reason nobody else can read your writing.

Same shape as a seed phrase, 12 words, a completely different job.

Hi @threemaapp,
What are your developments on Post #Quantum #Encryption, especially since the EU debate on the storing data longer…

@threemaapp I am curious about the progress, any news?

A locksmith fits your front door and hands you a key. The lock is exactly as good as he said it was. What you don't know is whether he dropped a spare in a drawer at the shop on the way home.

Encrypted software has the same story. Two apps, identical encryption, and one of them can read everything you write, because it kept a copy of your key.

There's a 2 minute test that settles it. Start a password reset and watch what you're offered.

Steganography 101 by Benn Jordan

When our government is spying on everything we post, we probably will still need to hide stuff.

WIth good steganography, hidden messages in plain sight will survive also social media compression, spotify, etc.

My husband and I use tuta (@Tutanota) for sending encrypted email. The account also includes a calendar.

I started with a free account just to test it out and then moved to the paid tier to get some more features.

No affiliation with the company, just a customer.

Anthropic’s Mythos found weaknesses in quantum resistant encryption algorithms HAWK and AES. There is no immediate risk, but this it highlights how frontier AI models are significantly increasing their capabilities to identify and exploit weaknesses in software, hardware, algorithms, processes, and people.

Some thoughts about Anthropic’s new cryptanalysis results

#AI #cryptography #encryption

Hey #encryption experts: has anyone thought about something similar to what three words, but for key fingerprints? This would be a huge #accessibility win. Right now, we have long hex strings we have to compare by hand, and a few visual/barcode type systems. I would love to be able to just verify "Correct Horse Battery Staple" with a friend. Easier to hear with a screen reader (b and c and d and e can sound similar in noisy environments when you're in a hurry), and of course none of the visual systems are really workable. Does the thing I want already exist somewhere? #a11y

@cryptography it would be a great idea to use #aes 256 for the #encryption for this task, but the problem is that aes (even in a secure authentication mode such as #gcm ) is static. this would revive the static problem. sure, more secure than the current key generation setup, but it's still static. and that means the NVDARemote server still has to have the key in order to work correctly.
any compromise of the NVDARemote server itself means that your key will be exposed. forget the compromise vector, even a rogue server administrator (something a cupple of NVDARemote servers are known for doing) can see the static key, hence why i want to use #public #key #cryptography for this project.
