FAQS

What is S/MIME?

S/MIME stands for Secure/Multipurpose Internet Mail Extensions. It's a standard for securely sending and receiving emails using digital signatures and encryption.

What is an S/MIME certificate?
An S/MIME certificate is a digital certificate used to authenticate the identity of an email sender and encrypt email content. It contains information such as the email address of the user, their public key, and information about the Certificate Authority (CA) that issued the certificate.
How does S/MIME work?
S/MIME works by using asymmetric encryption techniques. The sender's email client uses the recipient's public key to encrypt the email message. The recipient's email client then uses their private key to decrypt the message. Digital signatures are created using the sender's private key and can be verified using their public key.
Where can I get an S/MIME certificate?
S/MIME certificates can be obtained from trusted Certificate Authorities (CAs) or through internal certificate authorities within an organization. Many CAs offer S/MIME certificates for purchase, and some may provide them as part of a broader certificate package.
How long is an S/MIME certificate valid?
The validity period of an S/MIME certificate can vary depending on the issuing Certificate Authority and the certificate type. Typically, S/MIME certificates are valid for one to three years, after which they need to be renewed.
Do both the sender and recipient need S/MIME certificates?
While it's not strictly necessary for both the sender and recipient to have S/MIME certificates, the full benefits of S/MIME encryption and digital signatures are realized when both parties have certificates. However, even if the recipient doesn't have an S/MIME certificate, the sender can still digitally sign the email for authenticity.
Can S/MIME certificates be used for document signing?
While S/MIME certificates are primarily used for securing email communications, they can also be used for digitally signing documents, including Microsoft Office files and PDFs. This allows users to verify the authenticity and integrity of electronically signed documents.
Are S/MIME certificates compatible with all email clients?
Most modern email clients support S/MIME encryption and digital signatures, including Outlook, Thunderbird, Apple Mail, and various mobile email apps. However, compatibility may vary, and some clients may require additional configuration to work with S/MIME certificates.
Can S/MIME certificates be revoked?
Yes, S/MIME certificates can be revoked if they are compromised or if the user's email address changes. Certificate Authorities maintain Certificate Revocation Lists (CRLs) or use Online Certificate Status Protocol (OCSP) to revoke certificates before their expiration date if necessary.
