Hendrik,

     You might also think about filing a GitHub issue to capture it publicly!

Hendrik,

     Thank you for helping me get my brain around this potential feature. We very much appreciate these kinds of ideas. Currently, we are working heavily on the Podman API V2, but I have captured this as a backlogged feature that we will discuss in upcoming planning sessions. I've also captured this thread to come back to it and update when we get a chance to discuss and think about it further.

Best Regards

Hi Scott,

we would like to sign images using an HSM and those provide PKCS#11 (https://www.ibm.com/security/cryptocards/pciecc/overview, https://www.yubico.com/product/yubihsm-2, https://www.nitrokey.com/#comparison) and there does not seem to be any proper connection from that to the OpenPGP world. The only thing I found might be https://github.com/alonbl/gnupg-pkcs11-scd and that looks also a bit limited and dated. I'm currently especially interested in a way to use that IBM crypto card. A relatively easy solution might be to just store the signature hash in the signature file. To verify that it seem to be enough to something like "openssl dgst -sha256 -verify public.pem -signature manifest.sig manifest.json". My understanding so far is that this is actually a PKCS#1 hash calculation. Anyhow if I could get podman doing that openssl call instead of openpgp things would be working for me.

regards,
Hendrik

Hendrik,

     That's all that's supported today. Do you have any other tools you would be looking for?

Hi,

is OpenPGP the only supported image signing open supported by podman /
skopeo or are there other options? Using OpenGPG works quite fine for me
so far but in the end we are trying to sign an image using an IBM 4765
crypto card and so far have not figured out how this can play together.

thanks,
Hendrk
