Dear Dimitris (and all), I don’t think that „SHOULD effective date of 15 September, 2024” is necessary. It’s been long-standing best practice to do some form of linting. So making it mandatory in March 2025 shouldn’t be a problem.  However, I’m wondering how “…checked for conformance with the

Dear colleagues, We have started internal discussions about possible architectures to implement this new feature. This of course also involves the vendor of our CA system because architecture of the remote perspectives has big impacts on the changes needed in the CA system. One of the ideas

Dear Aaron, Interesting line of argumentation. Wouldn’t that conclude that -every- mis-issuance of a leaf certificate would be a violation of "all certificates that it issues MUST comply with one of the following certificate profiles" and thus would require the ICA to be revoked? That can’t be

Could we limit the Debian Weak keys to key sizes up to RSA 4096 bit? I don’t think that anybody “accidentally” creates an 8192 bit RSA key on a system vulnerable to Debian Weak keys. Kind regards Roman PS: Can somebody explain, why we only test close primes with 100 rounds and not e.g. 1000?

I would propose a pragmatic approach: Limit the Debian weak keys to be considered/rejected by CAs to an upper bound (e.g. 4096 or 8192 bits) assuming that any weak key above that has been intentionally manufactured by a security researcher. -Roman From: Servercert-wg On Behalf Of Wayne

Dear Ben, Mandatory participation has in my experience never resulted in more or better discussions. People will dial into the telco and let it run in the background to “earn the credits”. Also, what would happen after the 90 day suspension? Would the organization be removed as a CA/B member?
