    I can encrypt a message with your public key, and only you can decrypt it. The db will store the encrypted version.

    For example.

    This is not necessarily what/why they do it, just one example of how asymmetric ciphers can be useful in an email scenario.

      Just about nobody uses that. Your bank, your online store, your doctor, the state, and about everybody except Alice and Bob send you unencrypted mail.

      Encrypting your email once received is like storing your postcards in a safe.
