I’m contributing to OpenFHE Python from last year; today I’m pushing a new PR to allow for len() method for Ciphertext and Keys in Openfhe-Python/dev branch here.

Besides, I have reviewed the other two pending PRs, which seem to be OK to merge per me.

  2. Docker instance with Jupyter looks good as well : PR
