This great feedback. I'm definitely not a crypto expert. I'm happy to update the post with a different padding algorithm if you want to suggest one. I'm a little hesitant on swapping out RSA because I intentionally picked something relatively simple and familiar to folks, but yeah, will still do some research. Others had suggested ECC which I think is totally worth noting in the post one way or another.

Thank you!

The answer to your question is OAEP but I feel like I'd still be doing you a disservice there because I am convinced the answer ought to be box/secretbox or Fernet or AESGCM maybe -- but that hinges on my question about asymmetric cryptography which is elsewhere in the thread :)

Okay, it's updated to use OAEP and PSS padding. Thank you!
