How to send encrypted emails

Email encryption 

Email, when not encrypted, is like a postcard. Hackers can intercept and read them easily. Since many corporate emails contain sensitive information, they need to be encrypted to prevent spy and electronic mail meddling. Encrypted electronic mail check two critical components of a guarantee e-mail. content integrity : The encrypted emails are decrypted upon delivery where the content of the e-mail is verified, and an error message is thrown if the verification process fails. This decoding process makes it potential to detect any meddle. message privacy : When an electronic mail is encrypted, its content can only be read by the transmitter and the recipient, hence protected from unauthorized people .

What is S-MIME encryption? 

S/MIME (Secure/Multipurpose Internet Mail Extensions) provides an extra layer of security to your emails by encrypting them between the transmitter ‘s and recipient role ‘s servers, preventing unauthorized access to the data in the electronic mail.

How S-MIME encryption works 

S/MIME secures emails with two winder features .

• Email encryption: S/MIME provides email encryption making it indecipherable for users other than the intended recipients.
• Digital signature: S/MIME encryption digitally signs the emails between two S/MIME enabled users, ensuring sender authenticity.

S/MIME executes both electronic mail encoding and digital signature with populace and private keys. To know more about populace and private keys and how they function in e-mail encoding and digital signature, refer to this help page

Configuring S/MIME
