What is S/MIME?

S/MIME (Secure/Multipurpose Internet Mail Extensions) is a widely used standard for public key encryption and signing of MIME data. It provides a way to send encrypted and digitally signed emails, ensuring the confidentiality, integrity, and authentication of electronic communications. This allows recipients to verify the sender's identity and be confident that the message hasn't been tampered with during transit.
