Is it possible to have the public component of a key pair being capable only of decryption?

Sure? If you encrypt with the private key? That's kind of how the whole thing works. Are you asking something else?– schroeder ♦Nov 12, 2019 at 10:49

I thought the public key usually encrypts only and the private key decrypts and encrypts– CaharpukaNov 12, 2019 at 10:52

Here's the question, though. Is it really protected if you have the key to unlock it as a public key?– schroeder ♦Nov 12, 2019 at 10:58

The question is what is protected, if I just want to prove my identity by showing that I have the ability to encrypt arbitrary messages, shouldn't that be fine?– CaharpukaNov 12, 2019 at 11:42

You just described the "signing" process.– schroeder ♦Nov 12, 2019 at 11:48
