Key consistency checks

This requirement looks ready for approval, but has not been approved yet.

Every Debian member needs a GPG key of sufficient strength. In addition, all keys should be certified so we can link them to a real-world identity.

The normal requirements are:

the key should be type RSA and version 4 or greater, or an Eliptic Curve based key
the key should have the sign, certify and encrypt capabilities (subkeys are encouraged)
for an RSA key, the primary cryptographic material should be at least 4096 bits
the UIDs used by an applicant to work in the project should be signed (certified) by at least two existing Debian members (1 for DM applications)
as an alternative to the previous requirement, the key can be endorsed (see link at the bottom of the page) by multiple Debian Members (the number of required endorsements depends on the endorsement's age and nature)
pseudonyms or anonymity are acceptable in certain circumstances

If the key does not meet these requirements, and you would struggle to create one which does, contact Front Desk.

Keys are first searched in hkps://keyring.debian.org. If no key is found, then the key will be imported from hkps://keyserver.ubuntu.com/. Please ensure that you have sent your key to Ubuntu's key server. Sending public keys to keyring.debian.org will only work if your key is already in Debian's keyring and will only be taken into account after the Keyring Maintainers updated it. For Debian Maintainers and Developers, please remember to send your key to both servers.

This check will be approved manually by Front Desk as the application progresses.

For nm.debian.org, at 2026-06-09:
For the past 36 months, I have worked with Ivan Hu on acpica-unix.

For this past work, Ivan Hu sent mails using the email address ivan.hu@canonical.com
which is the one they're using on nm.debian.org, and they signed their work and
email using a GPG key with fingerprint AFAA 7BBA 1237 9356 93A2  0DD1 BD22 5722 BB40 051B.
Examples of those mails and contributions signed with that key are visible here
https://launchpad.net/~ivan.hu

I've made sure that they are able to decrypt encrypted messages sent to this key
and that they're able to sign messages with the same key.

Due to the long-term interactions we had, I'm convinced that Ivan Hu as they
present themselves on nm.debian.org is the rightful owner of both email
ivan.hu@canonical.com and GPG key AFAA 7BBA 1237 9356 93A2  0DD1 BD22 5722 BB40 051B.

Signed with key A368 78F4 6410 8681 600C B648 4417 3FA1 3D05 8888
