Secure/Multipurpose Internet Mail Extensions

An implementation of RFC 8551 also known as Secure/Multipurpose Internet Mail Extensions (S/MIME). S/MIME provides a consistent way to send and receive secure MIME data. Based on the popular Internet MIME standard, S/MIME provides the following cryptographic security services for electronic messaging applications: authentication, message integrity, and non-repudiation of origin (using digital signatures), and data confidentiality (using encryption).

Like other rasn core crates. This crate does not provide the ability to do authentication or encryption on its own, but instead provides shared data types for creating your own S/MIME clients and servers.
