#13 - Update SSH_SK_VERSION_MAJOR from 7 to 9

Open madaster97 opened this issue 1 year ago • 4 comments

Addressing issue 13, I copied this version of sk-api.h and changed a couple variables to match the names within (from message to data).

After that, I was able to create a key against Openssh_9.0p1, OpenSSL 1.1.1q Jul 5 2022 using my yubikey + windows hello.

By bumping from 7 to 9, we'll notably be missing support for 8 and a. See mentions of SSH_SK_VERSION_MAJOR in the OpenSSH release notes, and these commits that edit the sk-api.h file.

Many thanks! I’ll release a preview version based on this!

This is also working for me. I tested with OpenSSH_9.0p1 in cygwin (64-bit).

With OpenSSH_9.1p1, this is broken again:

Provider "/usr/lib/winhello.dll" implements unsupported version 0x00090000 (supported: 0x000a0000)
sign_and_send_pubkey: signing failed for ED25519-SK "/cygdrive/c/home/.ssh/id_ed25519_sk": invalid format

but it can be fixed with:

@tavrez , how do you think we should handle these frequent version bumps in OpenSSH-portable? Should we tag a release for major version 9, and then make a new one for major version a?

@ivan , it looks like this commit did more than just update the version number, and may have introduced other changes we need to make. Did you take a look at/test that?
