    Secure/Multipurpose Internet Mail Extension or Certificate is a technology that helps you to encrypt your valuable emails. It is an advanced way through which you can password-protect Outlook email so that only you and the required recipients can access the message. S/MIME certificate is the most effective way to encrypt email in Outlook because it provides you excellent security. However, It is a premium encryption technique.

    Prerequisites and Initial Setup

    Before using the S/MIME certificate, you need to make some necessary setups. These are mandatory to enable email encryption. You need to fulfill the below conditions.

    • Buy the S/MIME certificate for yourself and import it to MS Outlook. Also, you have to share it with all the recipients that you want to share your file.
    • The selected recipients should also install the Outlook encryption certificate to their Outlook application or any other S/MIME compatible email application. To open their encrypted emails, you must have their security certificate.

    Difference Between Encryption And Password Protection

    I will use the terms Encryption and Password Protection throughout this post, so lets first understand the difference between these two terms.

    Email encryption is to convert the contents of an email message from plain, readable text to cypher text which cant be deciphered by anyone other than the intended recipients. This prevents the contents of your email message from being seen by any unauthorized recipient. Whereas, we usually apply password protection to email attachments so that only authorized recipients can view such confidential attachments.

    What Is S/smime And What Is An S/mime Certificate

    Office 365 Encrypted Email Made EASY (Do Not Forward too!)

    When looking at ways to encrypt your email, you have to talk about S/MIME. An email security protocol called secure/multipurpose internet mail extension S/MIME certificates are used for end-to-end email encryption. Once you go through a validation process from a trusted CA, youll be issued a S/MIME certificate. Because it comes from trusted roots, these S/MIME certificates will tell email clients that youre trustworthy, which means that your S/MIME certificate will be supported by such mail clients.

    As mentioned, S/MIME certificates provide end-to-end encryption for your emails. They also allow the recipient of the email to verify the identity of the sender. This is done with the use of a digital signature. Only you can sign an email with your unique digital signature, allowing your recipient to verify it is you sending the email. This is not to be confused with an electronic signature, which is just a typed name.

    With end-to-end encryption and the digital signature, your email will be protected from being tampered with at all times and your recipients will be able to verify your identity. To learn more about S/MIME, their validation levels and the features they come with, I recommend reading our recently published blog on the topic.
