Here’s how it typically works: Message Encryption : The sender creates a message and encrypts it using a public key or another encryption method, rendering it unreadable to anyone without the corresponding private key or decryption tool. Posting to a Public Forum : Once encrypted, the message is posted in a public space, such as a discussion forum, comment section, blog, or even a social media platform.
