When generating WKD entries using gpg-wks-client --install-key, any uid with a URL in the comment results in a key file without the uid.
For example, given the following key with two uids:
pub rsa3072 2022-06-21 [SC] [expires: 2022-06-22]
7E1D0490C2604F4E162C47B63072E16A50CD434E
uid [ultimate] Jane Doe (https://www.example.org/~jane.doe) <noreply@example.org>
uid [ultimate] Jane Doe <jane.doe@example.org>
sub rsa3072 2022-06-21 [E] [expires: 2022-06-22]By following these instructions (retrieved 20 June 2022), WKD files can be created:
root@9ae492ba558c:/# gpg --list-options show-only-fpr-mbox -k "@example.org" | /usr/lib/gnupg/gpg-wks-client -v --install-key gpg-wks-client: gpg: Total number processed: 1 gpg-wks-client: using key with user id 'Jane Doe (https\x3a//www.example.org/~jane.doe) <noreply@example.org>' gpg-wks-client: gpg: Total number processed: 1 gpg-wks-client: directory 'openpgpkey/example.org' created gpg-wks-client: directory 'openpgpkey/example.org/hu' created gpg-wks-client: policy file 'openpgpkey/example.org/policy' created gpg-wks-client: key 7E1D0490C2604F4E162C47B63072E16A50CD434E published for 'noreply@example.org' gpg-wks-client: gpg: Total number processed: 1 gpg-wks-client: using key with user id 'Jane Doe <jane.doe@example.org>' gpg-wks-client: gpg: Total number processed: 1 gpg-wks-client: key 7E1D0490C2604F4E162C47B63072E16A50CD434E published for 'jane.doe@example.org'
This creates two key files, however only the key without a URL in the comment field includes the uid:
root@9ae492ba558c:/# gpg openpgpkey/example.org/hu/nwnwrk3rczw4ou5x56ibcrdatrgf1xag
