Commit Message

tpm2: Use OpenSSL functions for encrypting and signing using RSA keys

Use the CRT (Chinese Remainder Theorem) method for doing the RSA
operations. Unfortunately it is not sufficient to just pass the
precalculated dP, dQ, and qInv parameters to OpenSSL private key
crypto functions but it also needs D, which is a bit more involved
to calculate.

We are not caching D (private exponent) as part of the OBJECT since
the OBJECT lives in size-limited NVRAM and we would need to add
'D' to the privateExponent_t, which would make it bigger and which
would allow less keys to fit into memory, which in turn could be-
come an issue if we wanted to resume a TPM that filled up the NVRAM
with keys and now less keys would fit into the NVRAM.
