— but it serves well as a way of verifying message authenticity.Someone who receives an encrypted message that's purportedly from you can use your public key to decrypt the message and compare it with some expected value.

When your public key is used to encrypt a message, only you (as the holder of the private key) can decrypt that message.

This ensures confidentiality, one of the three aspects of secure message exchange.

If the result matches, they know that created the message.

In practice, more is involved in signing messages than just encrypting with your private key.

Anyone with access to the public key can use it to encrypt messages, which can then be decrypted only by the key owner.

Because separate keys are used for encrypting and decrypting messages, this form of cryptography is called .

With public-key cryptography, a party wanting to receive encrypted messages creates a pair of .

Each key value can be used separately to encrypt messages, but it cannot be used to decrypt the messages it was used to encrypt.

The secret could even take other forms, such as a language unknown to other parties who might have access to the messages.

The shared secret made the message exchange secure.

Instead, the other key in the pair must be used for the decryption.
