Smallstep: End-to-end encryption for distributed applications and the people who manage them. (we’re on Pacific Time)
Hey @etudurd I believe that KeyCloak is possible, we just don’t have documentation for it (yet). We have this open ticket — smallstep/certificates#110. If you follow through with the KeyCloak integration we’d love to hear about it. KeyCloak, being an OIDC provisioner, should work similarly to Gsuite, Okta, Azure AD, etc.
https://smallstep.com/blog/build-a-tiny-ca-with-raspberry-pi-yubikey/ — we're partnering with yubico to give away five build kits for TinyCA run on a raspberry PI with a yubikey. Details in the post!
ill publish it in January, probably with an all internal acme solution, if testing proves successful
BTW, I want to say thank you to the smallstep team for building such a solid system. I don't have any huge deployment or complex configuration, just a little homelab I was tinkering with over the holidays, but smallstep was easy to set up and start distributing certs. Took a bit to fully grok the relationship of how cert requests work and how to maintain everything, but once I did it's a breeze. I ended up wanting to distribute ssh host certs in k8s, so I expanded autocert to support them, and put up a pull request at smallstep/autocert#24
As follow ups to that PR, I'd like to add more testing, and to add support for sending SIGHUP signals to the primary pod process to reload the certs. I'll wait until you have a chance to review that PR first, as both pieces require touching controller.go, and I don't want to keep moving the review goalposts
Hello, I have been trying to get the tiny-ca rpi system up and running but I am having some issues after getting everything installed and configured. I made a post of r/homelab, link here.
I have gotten some issues worked out like the ca not using my internal dns server, but now I am stuck on the following error.

any help would be super useful
same with an fqdn
it works but the ssl is not verified

Hi all, I was looking for some input on exposing a DIY CA (following smallstep's guides) to the internet directly? In theory if I use
ufw to allow only port 443 and also set my network's firewall rules accordingly, it should be secure enough... Ideally I'd like to be able to generate SSH certificates from anywhere (whether I'm at home, which is 90% of the time these days, or out) to connect to my hosts. I've tried using Cloudflare, but testing with the step ca certificate command yielded x509: certificate signed by unknown authority errors. I guess I could also setup VPN to my home network (where the CA is hosted) and connect via VPN for SSH cert generation once per day if I'm not home, too...

Hi, sorry for the continued messages, but I've come across another question when working with step's SSH certs. I've also got some feedback on the step-ca docs but am not sure where to send it, or if you'd like me to send some here.
In any case, I've managed to get my SSH cert CA up and running and working with 90% of my hosts. I then had the thought to implement it with my GitHub account (non-enterprise), since GitHub can use SSH keys for authentication. Ultimately, I'm hoping that every time an SSH cert is generated on my machine, I'd setup a script so that it would replace the previous SSH cert on my GitHub account, so that way I'd have SSO for GitHub as well, in a sense.
In my preliminary testing, I have been trying to add my SSH cert public key to my Github account online manually and then testing with their
I guess what I'm wondering is, is something like this possible to do? I feel like I'm very close but can't quite extract the correct public key for some reason. I know on GitHub's enterprise plans I could even add my SSH CA user key, but can't justify the purchase of an enterprise plan for 1 user/myself. Thanks in advance, and apologies for the wall of text!

ssh -T git@github.com test. I've been extracting the currently active step SSH public key like this step ssh list --raw | step crypto key format --ssh on my local machine, with output looking something like this ecdsa-sha2-nistp256 AAAAE2VjZHNhLXN..., then adding it to my github account. However, that didn't seem to work and I keep getting Permission denied (publickey). errors when testing SSH. I've also tried uploading the output of step ssh list --raw, but their web UI didn't like that, even after changing the ecdsa-sha2-nistp256-cert-v01@openssh.com head to ecdsa-sha2-nistp256.I guess what I'm wondering is, is something like this possible to do?

A weird ask, but is it possible to have a custom web page at https://tinyca.lan? I would like to host the root CA for downloading on local clients.

Hello, while trying to deploy line by line the script provided in the SSH DIY example on the Host, i received the following error: The request lacked necessary authorization to be completed. Please see the certificate authority logs for more info. - at the “step ssh certificate ... —token $TOKEN” line. Do you know what I am missing and where i can find the step ca logs? Thank you!

Why isn't there a -Principal switch for "step ssh login ..." when this switch exists for "step ssh certificate ..."? It seems like an oversight since both commands generate a new SSH certificate and the ability to control the certificate principals should be equally useful in either situation. I posted this question earlier but retracted the post thinking that the -Identity switch listed in the documentation for "step ssh login ..." took the place of the -Principal switch, but no. In fact, I can't tell what it does. It doesn't cause any errors, doesn't have any effect on the generated certificate, and I can't find where it is handled in the code.

Hi all! Sorry if I've been away for so long. Issue in integration of Smallstep ACME with Proxmox certification system has now been solved. Reference: https://bugzilla.proxmox.com/show_bug.cgi?id=2462#c9

I'm continuing to work through the step ssh tools and revoked a ssh cert for the first time. It finally worked, but I still see the host in the list when I issue step ssh hosts. Should the host still be in there even though it's a principal on a revoked cert and doesn't appear on any active cert? Is there no way to clean this up?

Hello! Can somebody explain how stepca acme server checks the email in incoming requests?
I have stepca with admin@***.com JWK provisioner created during ca init and if I use this email for ACME - all works fine.
But I can't use any other emails. I tried to add another JWK provisioner with acme@***.com but I can't get the certificate for this email.
Can i get the certificate for other emails/provisioner emails or I should use only the first provisioner email?
I use Caddy as ACME client with simple config:
{
email acme@***.com
acme_ca https://acme.***.corp/acme/acme/directory
acme_ca_root /etc/caddy/root_ca.crt
}Provisioner List:
[
{
"type": "JWK",
"name": "admin@***.com",
"key": {
"use": "sig",
"kty": "EC",
"kid": "***",
"crv": "P-256",
"alg": "ES256",
"x": "***",
"y": "***"

The jwk provisioner doesn’t have anything to do with the ACME provisioner.
The JWK provisioners are, as you’ve probably found, just password provisioners. If you have the password to decrypt the JWK you can create any certificate you want.
ACME is separate, and in our implementation does not require an email.
When you say “use this email for ACME all works fine”, what do you mean?
In
step-ca the way to use ACME is by selecting the ACME provisioner from the provisioners drop down when you do step ca certificate.
So, give me an example of the
step ca certificate command you’re trying to run that is failing.
Looking to use certs for mTLS on clients.
and want to automate the renewal via task manager.
Guessing I may just need to one-time install the private key + cert as a p12 and then I can script the re-install of the .crt file during renewals.

Will validate that these settings actually work tomorrow when it's supposed to renew the cert. :)
Somewhat torn on whether it'd be better to run in
--daemon mode or just trigger task scheduler a couple times throughout day.
With manually I mean using yubico-piv-tool or something similar
