Please don't repeat terrible 90s pedagogy about RSA. Even in RSA, the padding for signatures and for encryption is different (for very important reasons). The fact that RSA encryption and RSA signatures share code (but are not identical) is just a quirk of RSA that instead of making the thing simpler to explain made it harder to explain well - people think this generalizes and try to understand where is the encryption in Ed25519 or whatever and are very confused.

If you want to point out the difference between "public key operation" (encrypt, verify) and "private key operation" (decrypt, sign), use those terms. That makes sense and the distinction is important.

People end up with basically misinformation in their heads and other people on stackoverflow (and IRL) spend lots of time trying to sort them out. You just made the problem a little worse. Please don't do that.
