I agree that this is a good idea in principle. However, the TPM code probably just uses a few flavors of SHA and nothing else, and this is not the part of CryptoPkg that I'd be concerned about. Most of the issues with OpenSSL are in the TLS part of the library, with the insanely complex ASN.1 parsing and X.509 handling etc etc. Could we build CryptoPei with fewer algorithms built into it? > > > If there are no objections I happily drop the USE_CRYPTO_DRIVER option > > > and switch over to the crypto driver unconditionally. > > > > Yeah, I'd prefer that. > > Noted for v2 next week. > > take care, > Gerd > -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
