Is it possible to encrypt data inside a smart contract on Ethereum?

Hello, everyone!

I’ve been practicing with smart contracts in Solidity on Ethereum, and I came across a question: is it possible to encrypt data directly within a smart contract?

My goal was to use the blockchain itself to encrypt information using someone else's public key. However, I noticed that Ethereum doesn’t seem to have native support for this.

So, my question is: is there any way to encrypt data within Ethereum using another person's public key, whether with RSA, ECC, or some other approach? Has anything been developed to achieve this?
