Description
I have been using CMAC with AES-128, or AES-CMAC as specified in RFC 4493, with the help of a gem that targets that RFC.
In several months, I will need to use CMAC with more ciphers, which is outside the scope of such gems.
After looking for alternative implementations, I think it would be best to make OpenSSL's CMAC implementation available to Ruby code.
Contributor guide
First steps
- Read the whole issue, then the project's contributing guide.
- Comment on the issue to say you are picking it up — it saves two people doing the same work.
- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
Research direction
Start by reviewing OpenSSL's CMAC implementation and how this extension exposes cryptographic APIs to Ruby. Define the Ruby-facing support for CMAC across ciphers and verify the supported behavior; the issue names no files or tests, so repository navigation and API design are required.
