Email encryption can rely on public-key cryptography, in which users can each publish a public key that others can use to encrypt messages to them, while keeping secret a private key they can use to decrypt such messages or to digitally encrypt and sign messages they send.mail encryption is encryption of email messages to protect the content from being read by other entities than the intended recipients. Email encryption may also include authentication. Email is prone to disclosure of information.
Generally, you use a certificate to encrypt other types of encryption keys in a database, or to sign code modules. Certificates and asymmetric keys can decrypt data that the other encrypts. Generally, you use asymmetric encryption to encrypt a symmetric key for storage in a database. A public key does not have a particular format like a certificate would have, and you cannot export it to a file. SQL Server contains features that enable you to create and manage certificates and keys for use with the server and database.
