Asymmetric Encryption in Five Minutes
Asymmetric Encryption
You generate both private and public keys.
You can share the public key (through email or host) which one who wants to message you.
He (who wants to send message) will encrypt the message from your public key and send you the encrypted message (through email or etc).
You received the message and you only can decrypt the message from your private key. Your private key has only with you.
Then no sharing the “message unlock key”.
