EMailVerschlüsselung

EMailVerschlüsselung, also known as email encryption, refers to the process of encoding the content of an electronic mail message to prevent unauthorized access. This ensures that only the intended recipient can read the message. There are two primary methods for achieving email encryption: transport layer encryption and end-to-end encryption.

Transport layer encryption, commonly implemented using TLS/SSL, protects the email as it travels between mail servers. While this secures the email during transit, the message may be temporarily stored unencrypted on the servers themselves.

End-to-end encryption, on the other hand, encrypts the email on the sender's device and can only be decrypted by the recipient's device. This provides a higher level of security, as the email content remains confidential even if the mail servers are compromised. Popular protocols for end-to-end email encryption include PGP (Pretty Good Privacy) and S/MIME (Secure/Multipurpose Internet Mail Extensions).

Implementing email encryption is crucial for protecting sensitive information, maintaining privacy, and complying with data protection regulations. While it can add a layer of complexity to sending and receiving emails, the security benefits are significant for individuals and organizations alike. Many email clients offer built-in support or integrations for encryption tools, making it increasingly accessible.
