I'm currently implementing Charm for a project, and I have realized that abenc_adapt_hybrid.py calls to symcrypto.py underneath for symmetrically encrypting the original message.
I wondered which symmetric encryption algorithm is implemented, and I realized that it is AES-CBC. CBC mode seems a bit outdated, and I wonder if there is any way of implementing AES-GCM instead.
I've been trying to import a MODE-GCM from charm.core.crypto.cryptobase with no luck so far. I guess there are many dependencies I'm not considering and that changing from CBC to GCM is not as straightforward as it seems.
Is anyone working on this, or is there a plan to substitute AES-CBC for AES-GCM?
Of course, there is also the possibility of having misunderstood everything and AES-GCM having already been implemented 😄. In which case, some pointers would be lovely 😊
