[Bug]: Yubikey AES management keys

[scj643]

Steps to Reproduce

1. Have a yubikey with an AES128, AES192, or AES256 management key.
   1. Generated with ykman piv access change-management-key -t -g -a AES256
2. Try to generate a key.

Your Environment

• OS - Fedora
• Version - 36

Expected Behavior

Key generation should succeed.

Actual Behavior

Get error Error: failed to load key manager: invalid managementKey: length is not 24 bytes or Error: failed to create key: error generating key: authenticating with management key: get auth challenge: smart card error 6a80: incorrect parameter in command data field if the key type is AES192

Additional Context

https://docs.yubico.com/hardware/yubikey/yk-5/tech-manual/yk5-piv-tech-desc.html#piv-aes-management-key documents the AES Key which then references https://csrc.nist.gov/publications/detail/sp/800-78/4/final

Hi @scj643, unfortunately, the YubiKey implementation is based on go-piv that only supports Triple DES management keys. I would recommend you to create an issue on go-piv.

But you might be able to use the PKCS#11 module using YubiKey YKCS11 driver available with yubico-piv-tool
