S/MIME: Secure/Multipurpose Internet Mail Extensions

Secure Multipurpose Internet Mail (S/MIME), a secure version of MIME, is defined to support encryption of email messages. S/MIME provides the following cryptographic security services for electronic messaging applications: authentication, message integrity and non-repudiation of origin and privacy and data security. S/MIME can be used by traditional mail user agents (MUAs) to add cryptographic security services to mail that is sent, and to interpret cryptographic security services in mail that is received. However, S/MIME is not restricted to mail; it can be used with any transport mechanism that transports MIME data, such as HTTP.
