Email Encryption & Decryption using C#

Question

Team, I want to send a secure encrypted email body & attachment using C#. I have seen some samples for encryption using S/MIME, but how the client will open the encrypted email and attachments from their email client (outlook). Kindly provide solution. Thanks, Suresh Rajamani

Hi sura,
You can try to use MimeKit to decrypt.
jstedfast provided a simple code example you can refer to.
Meanwhile, you can also try to encrypt a message with its public key, and then decrypt it with the private.
Here is a code example and hope help for you.
Best Regards,
