I have a private EC key held in a TPM 2.0 platform hierarchy. I'm encrypting a
message like this:
openssl cms -encrypt -in message.txt -out message.cipher transport.pem
Here, transport.pem is the cert. for the EC key held in the TPM. I'm
attempting to decrypt like this:
openssl cms -decrypt -in message.cipher -out /dev/stdout -inkey
0x81800001 -keyform engine -engine tpm2tss -recip transport.pem
Instead of seeing the original message text, I'm getting the following error:
engine "tpm2tss" set.
Error decrypting CMS using private key

routines:ecdh_simple_compute_key:missing private
key:../crypto/ec/ecdh_ossl.c:61:
It seems that the code is expecting the actual private key instead of
using the key held in the TPM?
