I wrote up a deep dive of the Linux random number generator highlights for the upcoming 5.17 & 5.18. There should be something for everyone in there - kernel programming, cryptography, a tiny bit of Windows reversing, and plenty of commit links. Enjoy!

cryptography ships numerous legacy symmetric algorithms that, anecdotally, have very low use. These algorithms have a variety of security drawbacks when compared to more modern equivalents (namely ...

We just released pyca/cryptography 35.0.0 to PyPI. Now with pure rust X.509 parsing! Super proud of the work @alex_gaynor and I did (but more Alex than me!). We're also shipping musllinux wheels, which makes our adoption of Rust simpler for Alpine users. 🎉

Exercise for cryptography students: the IND-CCA definition, but the challenge (encryption) oracle evaluates an unspecified adversarially-generated black-box predicate F(), and outputs plaintext anytime F(M)=1. Do you deploy this scheme?

The single biggest challenge I have in Rust right now is not lifetimes or ownership. It is that I cannot stop typing "fun" when I mean "fn". And the rust compiler is not hugely helpful when you do this.

I avoid commenting on members of congress & their inane remarks. But as a recent recipient of multiple death threats, this clear call to violence by a member of congress is beyond the pale. It’s disqualifying & un-American. If you associate w/ this, you’re part of the problem.
