What are the two main purposes of s MIME?
S/MIME provides the following cryptographic security services for electronic messaging applications: Authentication. Message integrity. Non-repudiation of origin (using digital signatures)
Does Gmail use S MIME?
Beyond that basic form of encryption, Gmail supports an enhanced standard known as S/MIME — or Secure/Multipurpose Internet Mail Extensions (gesundheit!). It’s available only for paid Google Workspace Suite accounts, so if you’re using a regular free Gmail account, it doesn’t apply to you.
What is the difference between MIME and S MIME?
S/MIME is a security-enhanced version of Multipurpose Internet Mail Extension (MIME).

What are the four principal services provided by S MIME?
The basic security services offered by S/MIME are authentication, non-repudiation of origin, message integrity, and message privacy.
What is PGP and S MIME?
S/MIME and PGP are both protocols used for authentication and privacy to messages over the internet.PGP is widely used for signing, encrypting and decrypting electronic data to maximize the security issues of data exchange. The protocol S/MIME refers to Secure/Multipurpose Internet Mail Extensions.
