My Dell XPS 9310 has secure boot enabled and the BIOS is up to date and there are no manual keys added there.
Can I download a ubuntu .ISO from anywhere and flash into any computer without worrying about malwares? Will it boot the USB driv… Continue reading Do I need to verify a .ISO before flashing, if my laptop has secure boot?
We recently adopted Sigstore to do signing of our binary artifacts using a keyless approach. The framework allows to use the OIDC token provided by the EKS cluster (https://docs.sigstore.dev/certificate_authority/oidc-in-fulcio/#kubernetes… Continue reading Using keyless signing from sigstore cosign
I was thinking about how to ensure the authenticity of Node.js packages that are installed from a public registry like npmjs.com. The only mechanisms (optionally) in place to my understanding are:
