I recently gave a long presentation on the topic of lawful access to encrypted data, first during the CSIRTs Network meeting, then at a local security meetup.

I don't want to share the slides, as they heavily depend on the voice track. In order to make the content accessible, I converted it into two posts on the cert.at website:

* Why is this so hard? https://www.cert.at/en/blog/2026/2/lawful-access-to-encrypted-data-why-is-this-so-hard-to-do

* General considerations https://www.cert.at/en/blog/2026/2/lawful-access-to-encrypted-data-general-considerations

Feedback is welcome.

Oh, that reminds me. Some of you may find a thing I wrote about lawful access and end-to-end encryption of interest too: https://mort.io/blog/cosi-lawful-access/
