Certainly :-) the RSA-2048 keys already match the fingerprints from the openssl-blacklist Debian package.<br>

<br>

We did this work several months ago but never found the time to make it publicly available. We managed to break down the big task and run jobs in parallel which made things a bit more interesting.<br>

<br>

It's nice we did this independently, I guess it increases the accuracy level of the resulted keys :)<br>

<br>

<br>

Cheers,<br>

Dimitris.<br>

<div>Dear friends,<br>

<br>

HARICA has generated the weak keys (RSA 2048 and 4096 bit lengths) from the vulnerable openssl package. We will generate 3072 bit keys as well and add them soon. The methodology is described in the following GitHub repo along with the produced keys:<br>

Some of the lesser used key sizes are mostly likely due to Subscriber typos (e.g., 2408 and 3048 were probably intended to be 2048, 4048 was probably intended to be either 2048 or 4096, etc), but some of the other ones look like they were deliberately chosen

The current draft proposes specifying a tool for ROCA (<a href="https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fcrocs-muni%2Froca&data=04%7C01%7Crob%40sectigo.com%7C97e795cc98524463488208d98fe8a506%7C0e9c48946caa465d96604b6968b49fb7%7C0%7C0%7C637699053033538098%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C2000&sdata=TW1BNTAMnhex5oKfM9X5zQYuV3PsvzpW8anj3EXOes8%3D&reserved=0" originalsrc="https://github.com/crocs-muni/roca" shash="YSZBrtaXEH1nm0LPIgVrqbO7b9Z+F3X7QSsr7ONdCCSA+32CBS1cumNzFm2AE/g5SZyzjygBsIptWXKSk1BW39KFk+9PSdtp4iRgB9YADl85QYQYJq/E4sHH/cd7Ad9N31ln5itv/P51bE/JUJxMcxcTbUleID9KIZvn92oq/XU=">https://github.com/crocs-muni/roca</a>)

 and an algorithm for Debian keys.<br>

<br>

The ROCA tool is subject to change or removal, just like the openssl-blacklist package. I propose we instead specify ROCA detection in terms of the paper (<a href="https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fcrocs.fi.muni.cz%2Fpublic%2Fpapers%2Frsa_ccs17&data=04%7C01%7Crob%40sectigo.com%7C97e795cc98524463488208d98fe8a506%7C0e9c48946caa465d96604b6968b49fb7%7C0%7C0%7C637699053033548058%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C2000&sdata=qNEwn8zBfVfKRnY5U5tyKoRU9Bn7gQPaVDUcWmSIbA4%3D&reserved=0" originalsrc="https://crocs.fi.muni.cz/public/papers/rsa_ccs17" shash="lF7We/ZX7z3WhVWC14nlzCy/EwgUPdoy8dCCJbQjYTg/86+GPdZAKP9eXuuPasJm/QLIZxWe89hMfk7fh9Sjt6q7dqpJ5/g6gbmzKBznMvTAHCNjLABb7MCS+03vHgrErgkE2Qn4onTSq0zDeyAJhagdX4f+7edEGFrhh7cUTcE=">https://crocs.fi.muni.cz/public/papers/rsa_ccs17</a>)

 and ask for permission from the authors to archive an unchanging copy as an addendum to the BRs.<br>

<br>

For Debian keys, what looks like an algorithm specification is actually a tool + algorithm specification. The tool is "OpenSSL 0.9.8c-1 up to versions before 0.9.8g-9 on Debian-based operating systems" (per CVE-2008-01666 -

https://cve.mitre.org/cgi-bin/cvename.cgi?name=2008-0166</a>). To ensure an unchanging copy of that, we should archive 3 copies of Debian, for the 3 word size + endianness combinations.<br>

<br>

The algorithm also needs an additional line: "v) using the command 'openssl req -nodes -subj / -newkey rsa:<Public Key length>'" (adapted from

<a href="https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fsources.debian.org%2Fdata%2Fmain%2Fo%2Fopenssl-blacklist%2F0.5-3%2Fexamples%2Fgen_certs.sh&data=04%7C01%7Crob%40sectigo.com%7C97e795cc98524463488208d98fe8a506%7C0e9c48946caa465d96604b6968b49fb7%7C0%7C0%7C637699053033558011%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C2000&sdata=NDhMEZBtAuxjnQAdEykDJCQ87zGKOzIi235AC6ceHr8%3D&reserved=0" originalsrc="https://sources.debian.org/data/main/o/openssl-blacklist/0.5-3/examples/gen_certs.sh" shash="rnzZUWOO06i9SoNFFiz+WQeJFPr2784VkVMhyf6PkZ6LNLLC/6RrGtQJUvvxeQm/lM+6+Kz31CdGeWfruWtuNIBK0lN6PxFSCGbFJC1OzppNW6wNsi7waXZuiM7Yc9g0xoILKdrCsHcoEhchrfMIh8nfBgi6rKuTDJ2h8WZhUto=">

https://sources.debian.org/data/main/o/openssl-blacklist/0.5-3/examples/gen_certs.sh</a>). Other tools that linked OpenSSL, like openvpn and openssh, generated different sets of keys. We can include or exclude openvpn and openssh keys, but should thoroughly

 specify.<br>

<br>

Lastly, I think we should archive openssl-blacklist, and include in the BRs: "A CA may reject the full set of Debian weak keys by rejecting this superset of the Debian weak keys:<br>

<br>

 - All RSA public keys with modulus lengths other than 2048 or 4096, and<br>

 - All RSA public keys with exponents other than 65537, and<br>

 - All RSA public keys that are detected as vulnerable by the openssl-vulnkey program in the openssl-blacklist package version 0.5-3 (see addendum), or an equivalent program."<br>

<br>

My reasoning: Given the difficulty of correctly setting up old Debian versions and generating weak keys for sizes that are not part of openssl-blacklist, I expect most CAs will choose this path. Given that, we should just say what we mean: the pregenerated

 list is fine if you restrict key sizes, but you don't *have* to restrict key sizes, so long as you have an alternate method to ensure you're not issuing for Debian weak keys at other sizes.<br>

<br>

*I'm considering specifying an algorithm to be functionally equivalent to specifying an "outcome," though I recognize this may be too hand-wavy.<br>
