S/MIME

S/MIME (Secure/Multipurpose Internet Mail Extensions) is a technology that helps protect email communication by securing its contents. It achieves this through encryption, which transforms your message into a secret code only the intended recipient can decode, and digital signatures, which verify the sender's identity and ensure the message hasn't been altered. This process ensures that sensitive information remains private, authentic, and intact during transmission over the internet, providing both confidentiality and trustworthiness in email exchanges.
