Digital Signatures and Encryption for Emails
S/MIME (Secure Multipurpose Internet Mail Extensions) is a standard for public key encryption and signing of MIME data.Through encryption and the use of digital signatures, S/MIME helps to protect users from email-related threats and increase email security.
Digitally signed emails help against spoofing and phishing attacks – the sender’s identity is clearly visible to the recipients to protect them from any fake emails.
