We currently use OpenSSL 1.0.2h, we are in the process of
upgrading to OpenSSL 1.1.1. To address some legacy functionalities we are planning
to write engines for OpenSSL 1.0.2h offload crypto operation to external components.
We have few queries regarding the same
we offload all crypto operations (Digest, Encryption/decryption, RSA,
ECDSA, DRBG etc) using Engines in OpenSSL 1.0.2h
not, is it must to upgrade to OpenSSL 1.1.1 to achieve the same?
