Short answer - it's only an exchange of public keys; private keys don't go anywhere. Public key is safe to share.
Long answer - With asymmetric cryptography, your private key doesn't have to be sent anywhere. Your public key is the key to encrypt messages for sending to you; your private key is the key to decrypt those messages from others, after they've sent things to you using your public key for encryption.
Your private key is also used to calculate checksums, which can be verified without the private key, using the public key instead - but the checksum can't be calculated with the public key, so it basically proves the private keyholder created the checksum.
Since nostr public keys aren't really dangerous to share, there's. The bigger concern is backdoors in your own system, especially since most modern electronics include hardware-level backdoors.
Some people like @hzrd149 have "signer devices" that should in theory be very secure because the device should have no backdoors in it, leaving no reasonable way the private key is leaving the device.
I have to apologize though for wasting this time with my caveman-brained, backdoor-mentioning reply instead of suggesting you go ask a chat bot, as the almighty GrapheneOS (npub1235…0ht5) devs have told me many times how I'm "not technical," I'm worse at providing input than an LLM, no better than a spam bot, and no one wants my input.
Regretfully, the glorious GrapheneOS folks didn't show up to answer your question in the first hour after you posted, and neither did anyone else I can see on my nostr relays, and I have this arrogance that makes me think I deserve to interact with my fellow humans; even though I don't know if I've been able to protect Digit, the person who made me care enough about questions like yours to take time answering you. In fact, I'm such a failure that so far, I haven't even been able to get the GrapheneOS devs to apologize for refusing to say they hope Digit is safe a single time throughout their many replies attacking me. I'm not even sure why I'm answering you when most people on nostr constantly make it clear that they agree with GrapheneOS, don't want my input, and don't care if Digit is alive.

quoting nevent1q…xy9ewhoever relays stuff 🇵🇸🏴☠️🇺🇲 (nprofile…djma) You baselessly claim there are backdoors without substantiating any of it. It's worthless input equivalent to a spam bot. You're less capable of holding a conversation than an LLM. No one is fooled by it. You haven't tricked anyone into believing you're technical. You're simply wasting your time and other people's time posting the equivalent to auto-generated spam.
