End-to-end encryption
End-to-end encryption ensures that only the sender and intended recipient can read the email. This is achieved by encrypting the message on the sender's device and decrypting it on the recipient's device, making it inaccessible to anyone in between.
Transport Layer Security (TLS)
TLS encrypts the communication between email servers, ensuring that the data is protected while in transit. It provides a secure channel for the exchange of emails, preventing unauthorized access and tampering.
Public Key Infrastructure (PKI)
PKI utilizes a system of public and private keys to encrypt and decrypt emails. The sender uses the recipient's public key to encrypt the message, and the recipient uses their private key to decrypt it, ensuring secure communication.
