OK. That’s done
I m compressing first encrypting second Next question: I m compressing 1Mb chunks at a time. Can I encrypt those chunks safely instead of waiting for the compression to finish and then encrypt it all ?

Generate a symmetric key, use that to encrypt the payload, and encrypt the key itself under the public key. Composing this in a safe manner is tricky though, so you may want to consider PyNaCl for this.

Not much of a python dev but I managed to put together some code to encrypt/decrypt files using RSA But like the entire fine, not just some intermediate password public_key.encrypt of 11 Mb ( ~47 000 * 190 byte pieces) file took about 8 seconds private_key.decrypt of the same file took 143 seconds profiler said 142 of those came from _openssl.EVP_PKEY_decrypt I m running x64 Python version 3.8.5 And I just installed the cryptography module today through pip Am I being stupid trying to do this and not go with asymmetric encryption for the intermediate and go symmetric from there ?
