Email encryption is a method used to protect the content of emails from unauthorized access. By converting the email's information into a coded format, only the intended recipient with the correct decryption key can read the message. This ensures that sensitive information, such as personal data or business secrets, remains confidential during transmission. There are various types of encryption methods, including symmetric and asymmetric encryption. Symmetric encryption uses the same key for both encryption and decryption, while asymmetric encryption employs a pair of keys: a public key for encryption and a private key for decryption. This technology is essential for maintaining privacy and security in digital communication.
