Hi Daminan! Hmmm... thought about a little... when i use -vvv with ssh-keygen -Qf i see "debug1:..." So i think, debug is compiled in. ssh-keygen --help gives me ssh-keygen -k -f krl_file [-u] [-s ca_public] [-z version_number] file ... so... option -z is not the serial of the certificate, it is the version-number of the KRL-File... My openssh-Verision from Debian is 1:7.4p1-10+deb9u7. Maybe, this openssh-version does not support revoking a certificate by it's serialnumber. This leads me to the next question... The serial-number of a certificate is uniq over all certificates, or is it allowed, to increment serial-numbers for each certificate separate? How is the design? thank you jakob Am 16.09.19 um 04:18 schrieb Damien Miller: > On Fri, 13 Sep 2019, Jakob Schürz wrote: > >> Hi there! >> >> What am I doing wrong? >> >> I created a ssh-certificate >> >> id_user_rsa-cert.pub with this dump: >> >> id_user_rsa-cert.pub: >> root@host # ssh-keygen -Lf id_user_rsa-cert.pub >> Type: ssh-rsa-cert-v01@xxxxxxxxxxx user certificate >> Public key: RSA-CERT SHA256:kPitwgxblaUH4viBoFoozSPq9Pblubbedk >> Signing CA: ED25519 SHA256:8p2foobarQo3Tfcblubb5+I5cboeckvpnktiHdUs >> Key ID: "test@myhost.mydomain.example" >> Serial: 18 >> Valid: from 2019-07-29T02:08:00 to 2020-07-28T02:09:43 >> Principals: >> test >> Critical Options: (none) >> Extensions: >> permit-X11-forwarding >> permit-agent-forwarding >> permit-port-forwarding >> permit-pty >> permit-user-rc >> >> >> Now i try to revoke this certificate with >> >> ssh-keygen -s ../user_ca.pub -kf /etc/ssh/revoked_keys -z 17 >> id_user_rsa-cert.pub >> >> The serial is 1 less the serial of my created certificate >> >> Check, if my certificate is valid >> >> root@host # ssh-keygen -Qf /etc/ssh/revoked_keys id_user_rsa-cert.pub >> id_user_rsa-cert.pub (test on myhost - created by ansible (1564358942)): >> REVOKED >> >> Why?
