Webb29 nov. 2024 · The public key is shareable, in that it’s a file that you can treat like an address in a phone book: it’s public, people know to find you there, you can share it widely, and people know to encrypt messages to you there. You can share your public key with anyone who wants to communicate with you; it doesn’t matter who sees it.
