Compute HMAC using nCipher ENGINE and HSM-based symmetric key

[Ron Kundla]

Hello!

I have a requirement to generate a HMAC value using a secret/symmetric
key inside the HSM. I have seen examples that use public/private keys
to do such a thing, but nothing that would use an AES or a
nCipher-specific HMAC key.

Does OpenSSL support this function using the ENGINE subsystem?

Thanks,
Ron
