It works! Beyond passkeys, I can encrypt a file in the browser with typage and WebAuthn, and then decrypt it with the same YubiKey from the CLI with age-plugin-fido2prf.

what's the go-to binary security check tool? Just for basic stuff like source fortification, stack canaries etc.

Is github.com/slimm609/che... the go-to tool?

Stability in AFL++/LibAFL is quantified by the percentage of edges in the target that are considered “stable”. If repeatedly sending identical inputs results in the data traversing the same path through the target each time, then the stability is determined to be 100%.

I thought I'd share some fuzzing tips.

In AFL, filename of a crash gives rough information about where it originated. The name id:000000,sig:06,src:000002,time:286,execs:13105,op:havoc,rep:4 indicates that the crash with ID 0 caused a signal 6 in the target program...

Just submitted my first small kernel patch 🎉 I have to admit the experience was both intimidating and only partially clear.

I included typos, sent the patch only to maintainers and not the mailinglist and top-posted - all no-goes 😓
