SCXX Ballot proposal: Debian Weak keys
<div><br>

<div>This ballot modifies the “Baseline Requirements for the Issuance and Management of Publicly-Trusted Certificates” as follows, based on Version 1.7.9:</div>
<div><br>
</div>
<div><b>Proposed ballot language:</b></div>
<div><br>
</div>
<div>4.9.1.1 Reasons for Revoking a Subscriber Certificate</div>
<div> </div>
<div><b>REPLACE:</b></div>
<div><br>
</div>
<div>4. The CA is made aware of a demonstrated or proven method that can easily compute the Subscriber’s Private Key based on the Public Key in the Certificate (such as a Debian weak key, see https://wiki.debian.org/SSLkeys)</div>

<div><br>
</div>
<div>---</div>
<div><br>
</div>
<div>6.1.1.3. Subscriber Key Pair Generation</div>
<div><br>
</div>
<div><b>REPLACE:</b></div>
<div><br>
</div>
<div>The CA SHALL reject a certificate request if one or more of the following conditions are met:</div>
<div><br>
</div>
<div>1. The Key Pair does not meet the requirements set forth in Section 6.1.5 and/or Section 6.1.6;</div>
<div><br>
</div>
<div>2. There is clear evidence that the specific method used to generate the Private Key was flawed;</div>
<div><br>
</div>
<div>3. The CA is aware of a demonstrated or proven method that exposes the Applicant's Private Key to compromise;</div>
<div><br>
</div>
<div>4. The CA has previously been made aware that the Applicant's Private Key has suffered a Key Compromise, such as through the provisions of Section 4.9.1.1;</div>
<div><br>
</div>
<div>5. The CA is aware of a demonstrated or proven method to easily compute the Applicant's Private Key based on the Public Key (such as a Debian weak key, see https://wiki.debian.org/SSLkeys).</div>
<div><br>
</div>
<div><b>With:</b></div>
<div><br>
</div>
<div>The CA SHALL reject a certificate request if one or more of the following occurs:</div>
<div><br>
</div>
<div>1) The requested Public Key does not meet the requirements set forth in Sections 6.1.5 and/or 6.1.6;</div>
<div><br>
</div>
<div>2) The CA is aware of a demonstrated or proven method that exposes the Subscriber's Private Key to compromise;</div>
<div><br>
</div>
<div>3) The CA has previously been made aware that the Subscriber's Private Key has suffered a Key Compromise, such as through the provisions of Section 4.9.1.1;</div>
<div><br>
</div>
<div>4) The Public Key corresponds to an industry demonstrated weak Private Key, in particular:</div>
<div><br>
</div>
<div>a) In the case of ROCA vulnerability, the CA SHALL reject keys identified by the tools available at https://github.com/crocs-muni/roca or equivalent.</div>
<div><br>
</div>
<div>b) In the case of Debian weak keys (https://wiki.debian.org/SSLkeys), the CA SHALL reject keys generated by the flawed OpenSSL version with the combination of the parameters described in 6.1.1.4.<br>
<br>
<b>ADD:</b><br>
</div>
<div><br>
</div>
<div>6.1.1.4 Subscriber Key Pair Parameters</div>
<div><br>
</div>
<div>The CA SHALL reject keys (per 6.1.1.3(b)) if the following parameters apply:
</div>
<div><br>
</div>
<div>i) Big-endian 32-bit, little-endian 32-bit, and little-endian 64-bit architecture;</div>
<div><br>
</div>
<div>ii) Process ID of 0 to 32767, inclusive;</div>
<div><br>
</div>
<div>iii) All RSA Public Key lengths supported by the CA;</div>
<div><br>
</div>
<div>iv) rnd, nornd, and noreadrnd OpenSSL random file state.</div>
<div><br>
</div>
<div>These are some suggested tools that CAs MAY use to obtain lists of Debian weak keys:</div>
<div><br>
</div>
<div> - https://github.com/CVE-2008-0166 provides a generator, for the complete set of parameters listed above, that runs on any modern 64-bit Linux system; it also provides complete sets of pregenerated keys for the most common RSA key sizes.</div>
<div> - https://github.com/HARICA-official/debian-weak-keys provides a generator, for a subset of the parameters listed above, that can take advantage of a computer cluster.</div>

Hello Rob,<br>
<br>
Thanks for the useful suggestion. We've amended our proposed ballot language accordingly.<br>
<br>
We would still like to determine the best way to direct CAs to the weak key populations assembled through the work of yourself and HARICA.<br>
<br>
On the broader question of how to proceed, we see three options for community consideration:<br>
<br>
- Carry forward with this proposed ballot;<br>
- Consider adding this language to a future cleanup ballot; or<br>
- Declaring that current language and guidance are sufficient.<br>
<br>
To recap, the ur-issue is itself from 2006-2008, our initial request for input on this matter was made in April 2020 and this ballot language has been under (sporadic) discussion since December 2020. Given the narrow focus of the issue itself, this could certainly
be considered a low priority, and thus wrapped into a future cleanup ballot (rather than undergoing a separate ballot procedure).<br>
<br>
However, we note that the impetus for this ballot discussion was failure of a publicly-trusted CA to prevent issuance of a certificate using a Debian weak key in March 2020. We aim to ensure this doesn't happen again by clear delineation of expected practices
(and direction to appropriate resources) in our Baseline Requirements.<br>
<br>
We believe this proposal offers clearer guidance on this matter than the current BR language, and is an opportunity to make an ecosystem-wide improvement in CA practices.<br>
<br>
We hope to discuss this in our regular call and very much welcome community input.<br>
<br>
Regards,<br>
<br>
Chris K<br>

Hi Christopher. What sort of "actions" are envisaged here? If a CA is processing a certificate request that contains a (for example) RSA-4088 public key (i.e., a key size not covered by an available Debian weak list), either the CA is going to issue the cert
or they're not. What, concretely, does "minimize the probability of certificate issuance" actually mean?</div>

<br>
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>

<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>
<ul>

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
(e.g., 2432 is 2048+384). Is it worth generating Debian weak keys/blocklists for any of these key sizes?</div>

<div dir="ltr">Thanks for your continued efforts to improve this part of the BRs! Let's Encrypt is in theory interested in endorsing, but I think it still needs a bit of work. Thanks for incorporating my most recent comments on endianness and word size vs 11
platforms.<br>
<br>
Goals: We want CAs to consistently not issue certificates for weak keys in general, and also in the specific case of Debian and ROCA keys. We want the definition of Debian and ROCA keys to be clear and actionable for as long as possible - say, at least twenty
years.<br>
<br>
We have three ways to specify Debian and ROCA keys: With a list, with a tool, or with an algorithm*. The original revision of this ballot proposed to use a list (<a href="https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.cabforum.org%2Fpipermail%2Fservercert-wg%2F2020-April%2F001821.html&data=04%7C01%7Crob%40sectigo.com%7Ca505320417514683604108d962906fbc%7C0e9c48946caa465d96604b6968b49fb7%7C0%7C0%7C637649196427648716%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=YvYqBm1HlforxiPN1zQbeSUf4AW04sLaYCuEjiLfFzA%3D&reserved=0" originalsrc="https://lists.cabforum.org/pipermail/servercert-wg/2020-April/001821.html" shash="AZXChxEe7L7Uriz+JjF9FbHaBQotKLobWwqav3S5ml6TEWL8R34iE+6sX3/iEILo9Hnhojzca+IvYjvotdeQ7dCyTO3GCbU7NfYgt0XQus/j/W3eu1BliVsuCTBCGu7Y3o919gT4aeU+WN3Fj8UmDpKf5q4eq29sQIlIq0TmJr4=">https://lists.cabforum.org/pipermail/servercert-wg/2020-April/001821.html</a>).
There were two objections:<br>
<br>
- The list (openssl-blacklist) is subject to change or removal.<br>
- The list only covers 2048 and 4096 bit keys.<br>
<br>
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%7Ca505320417514683604108d962906fbc%7C0e9c48946caa465d96604b6968b49fb7%7C0%7C0%7C637649196427658670%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=Ybwh7xp1zVuEj8avYqsDHslP2NrZEzoOPOx4bEI4%2B5I%3D&reserved=0" originalsrc="https://github.com/crocs-muni/roca" shash="uYowUAts3PcSd7iXWK6RAjClS6SwfaKj/Er4AhlmV3ZD+l3jQzt+ppfWzJ2aA4rIhaGsUkdq8ajovInHUY5zbR52KoiYtvu73A23wmyhlTIHoNKj72dANG3q/zBty7UwqBR5YjdqLjcfkzX+2iOOFT1Tc33kne6tKNv740bmO8g=">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%7Ca505320417514683604108d962906fbc%7C0e9c48946caa465d96604b6968b49fb7%7C0%7C0%7C637649196427658670%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=6550FZqHPDF6KM3F17d6rKeCfP0Zau%2BGWYwPYal7acY%3D&reserved=0" originalsrc="https://crocs.fi.muni.cz/public/papers/rsa_ccs17" shash="O8NGLs/FjVlItXhJzexXojjO0O+llkrxJIRf9xtgKUOBa9eJcfn7aqHPZXlKMfE36it8tJRzW2m5d349Y8XDD1q0YjSvnmuCK840/JKGXZlYJkwDCBXpkim2z/blAuaQg1GwNIvqziLBIA0NyvxI6xjqBe8GlmG7A838k1DHY6E=">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 -
<a href="https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fcve.mitre.org%2Fcgi-bin%2Fcvename.cgi%3Fname%3D2008-0166&data=04%7C01%7Crob%40sectigo.com%7Ca505320417514683604108d962906fbc%7C0e9c48946caa465d96604b6968b49fb7%7C0%7C0%7C637649196427658670%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=QdZIVGYB%2B3jgtU05nS52CnLACgzSkjXmC%2FonOtuWFa4%3D&reserved=0" originalsrc="https://cve.mitre.org/cgi-bin/cvename.cgi?name=2008-0166" shash="oAdhV+ApQ0aqAK/NbjorqR5EeoCkWzOECn6xPUsDFK9tbMq++myyK8BhkKPKRFwyInFQcGqh6sn1ha9Heo8KM0ZGxWGWqAev8+Ncczx5bg5DNFUbsptPERsOhbteZOwVXonwYb+lSNikRcMKTFU8bGk7qpGMvBaNVd7kQYFzz5I=">
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%7Ca505320417514683604108d962906fbc%7C0e9c48946caa465d96604b6968b49fb7%7C0%7C0%7C637649196427668630%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=%2FmV%2BEdnUMMSfAiJBQfFxfcq98T5WzVgTj%2Bhqjbt7AJY%3D&reserved=0" originalsrc="https://sources.debian.org/data/main/o/openssl-blacklist/0.5-3/examples/gen_certs.sh" shash="cPRUtVb/SlGHTMBUyuetnjDmOeJcU5HzoIPdR5qQ3LYeWp1gyh9noY5zbo33DuXLfqdEsmAl4pzYwL/UfQWb8GCRhHFKonUPNpAx9ukRwVvsZ4LIp2fx05xDCJOQ2aAicpsFfiNznXeOYftg1v2qsH88BDAguVZU52WGU7Q+biU=">
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>
