Description of problem:
When I use different encryption and signing algorithm in keylime.conf, than default RSA the agent cannot be registered and registration fail. I used ECC instead of RSA for encryption and ECSCHNORR instead of RSASSA for signing.
Version-Release number of selected component (if applicable):
TPM Manufacturer: swtpm
Keylime version: keylime-99-1.noarch
How reproducible:
First method:
1.Install tmt via sudo dnf install -y tmt-all
2.Clone specific branch where is test scenario for different algorithm
- git clone --branch default_algorithm https://github.com/Koncpa/keylime-tests.git
3.Run test scenario with needed setup tasks, need to be inside cloned repo dir.
- tmt run -vvv plan --name rust-keylime prepare discover -h fmf provision --how virtual -i Fedora-36 -c system execute --how tmt --interactive login finish
Second method:
1.Setup swtpm on machine
2.Install keylime package
3.Change in keylime.conf encryption algorithm to tpm_encryption_alg = ecc and signing algorithm to tpm_signing_alg = ecschnorr
4.Run keylime verifier,registrar,agent and wait for registration of agent.
Actual results:
Agent registration will fail.
Expected results:
Agent registration will be succesfull.
