A digital signature is a unique digital mark that verifies that an email message originated from the signer and that it has not been altered. It ensures that a message you're reading has not been changed since it was digitally signed, and that the message was not "spoofed" (sent by an impostor). At Indiana University, the primary means of digitally signing email is to use an S/MIME (Secure/Multipurpose Internet Mail Extensions) client certificate.
To use an S/MIME client certificate to digitally sign your email at IU, you need to:
- ARCHIVED: Get an S/MIME client certificate
- Install your certificate, using the instructions for your email client:
- Renew your client certificate when it expires
S/MIME client certificates also can be used to send and receive encrypted messages within the IU Exchange system. For more, see ARCHIVED: About email encryption using S/MIME client certificates at IU.
For more about digital signatures, see Microsoft's Digital signatures and certificates.
