[imranmehdi5511]

I have a aes256 encryption code written in c programming language, How do I get the makefile and manifest file for it? How to create these files or automatically create them? I have been searching for months but no detailed answer on this topic

Hi @imranmehdi5511!

How do I get the makefile and manifest file for it? How to create these files or automatically create them?

For Makefiles, there's nothing special in working w/ Gramine, so you have to either create it on your own or use some build systems like CMake. Basically, you could just leverage your original Makefiles of this aes256 encryption code written in c programming language and sign the manifest with gramine-sgx-sign tool, see https://gramine.readthedocs.io/en/latest/manpages/gramine-sgx-sign.html.

For manifests, unfortunately there is no such auto-generation tool available in Gramine, i.e., you have to create your application-specific manifest file on your own by following https://gramine.readthedocs.io/en/latest/manifest-syntax.html. There are acutally a bunch of application examples available here: https://github.com/gramineproject/gramine/tree/master/CI-Examples. So you could start with a thoroughly documented example of Redis (https://github.com/gramineproject/gramine/blob/master/CI-Examples/redis/redis-server.manifest.template) to understand manifest options.
