End-to-end encryption
End-to-end encryption is a highly effective email encryption solution that ensures that only the sender and the intended recipient can read the message. This method encrypts the message on the sender's device and decrypts it on the recipient's device, making it nearly impossible for anyone else to intercept and decipher the message.
Transport Layer Security (TLS)
TLS is a protocol that encrypts email communications between mail servers, providing a secure channel for data transmission. It is widely used by email service providers to protect emails in transit, ensuring that they cannot be intercepted or tampered with by unauthorized parties.
OpenPGP and S/MIME
OpenPGP and S/MIME are standards for email encryption that use public key cryptography to secure email communications. OpenPGP is often used for personal email encryption, while S/MIME is commonly employed in corporate environments. Both standards provide strong encryption for email content and attachments.
Advanced Encryption Standard (AES)
AES is a symmetric encryption algorithm that is widely used to secure email data at rest. It provides a high level of security by encrypting the contents of email messages and attachments stored on email servers, ensuring that unauthorized access to the data is prevented.
