S/MIME (Secure/Multipurpose Internet Mail Extensions) provides a standard way to send and receive secure electronic mail. Based on the popular Internet MIME standard (RFC 1521), S/MIME provides the following cryptographic security services for electronic messaging applications: authentication, message integrity and non-repudiation of origin (using digital signatures) and privacy and data security (using encryption).
