Project mention: Heartbleed and XZ Backdoor Learnings: Open Source Infrastructure Can Be Improved Efficiently With Moderate Funding | dev.to | 2024-04-07Today, April 7th, 2024, marks the 10-year anniversary since CVE-2014-0160 was published. This security vulnerability known as "Heartbleed" was a flaw in the OpenSSL cryptography software, the most popular option to implement Transport Layer Security (TLS). In more layman's terms, if you type https:// in your browser address bar, chances are high that you are interacting with OpenSSL.
Project mention: CyberChef from GCHQ: The Cyber Swiss Army Knife | news.ycombinator.com | 2024-02-01I also discovered Ciphey. Neat little tool indeed, but it's being deprecated. It's mentioned in this issue[1] and being replaced with Ares[2]. Neither could decipher this strange encryption[3] I used it on :(

[3] "dEFLWWFKQWxRQW16RnkvbTZML0lsdz09" original text is "hacker"
I don't need/use IDA, Nemlei just used https://obfuscator.io/, which just obfuscates the crap out of the code using various known methods (which I won't go into detail, it's public knowledge) and an un-obfuscation was cooked up by others. The one fucked-up thing the website does is randomizing function names, it just changes every variable/function name. We can't "un-obfuscate" those, so it's up to our brains to figure out what the code does, and change the names back.
Project mention: Libsodium: A modern, portable, easy to use crypto library | /r/hackernews | 2023-09-18
Project mention: Dropbox: How to opt out of 3rd party AI partner access to your Dropbox | news.ycombinator.com | 2023-12-13the best way to do this is with https://cryptomator.org

Incentives are much harder but smart contracts can handle the tech part.
Going this route eventually you quickly have "quantum AI app store" and your system of government is a 12GB download. Can't even say if it's a good idea compared to e.g. anarcho-primitivism.

Congratulations to the authors, this was a feature that was dearly missing from pyca/cryptography. It took a long time to get right.
For the history: https://github.com/pyca/cryptography/issues/2381
Super intriguing. Thanks for sharing!
It reminds me a bit of an early Go project called Upspin [1]. And also a bit of Solid [2]. Did you get any inspiration from them?
What excites me about your project is that you're addressing the elephant in the room when it comes to data sovereignty (~nobody wants to self-host a personal database but their personal devices aren't publicly accessible) in an elegant way.
By storing the data on my personal device and (presumably?) paying for a managed relay (and maybe an encrypted backup), I can keep my data in my physical possession, but I won't have to host anything on my own. Is that the idea?

Project mention: The Hidden World Of Dumps Store | CVV Shops: The Lucrative World of Credit Card Fraud! | /r/darknetplan | 2023-07-09This sub is not about TOR and all the seediness that goes on there but rather about creating darknets, by which we/they mean mesh networks and encrypted networks using tools like https://github.com/cjdelisle/cjdns/
Only XMR and GRIN. Everything else lacks transactional uniformity, or is centralized corpo garbage, or both!
