CMS (PKCS#7) -sign not generating any output

[baileyje]

I am attempting to create a CMS message using the TPM2 provider. I am executing the following:

echo "test" | sudo openssl cms -binary -sign -signer ident.crt -inkey ident.key -keyform pem -outform pem -nodetach -provider tpm2 -provider default

The command succeeds with a successful return code, but no output is created. We use this command all the time with the default provider and I have confirmed it with a non TPM backed key.

Any ideas?
