| //! |
| //! This module is used by [`x509`] and other certificate building functions |
| //! to describe time, strings, and objects. |
| //! |
| //! Abstract Syntax Notation One is an interface description language. |
| //! The specification comes from [X.208] by OSI, and rewritten in X.680. |
| //! ASN.1 describes properties of an object with a type set. Those types |
| //! can be atomic, structured, choice, and other (CHOICE and ANY). These |
| //! types are expressed as a number and the assignment operator ::= gives |
| //! the type a name. |
| //! |
| //! The implementation here provides a subset of the ASN.1 types that OpenSSL |
| //! uses, especially in the properties of a certificate used in HTTPS. |
| //! |
| //! [X.208]: https://www.itu.int/rec/T-REC-X.208-198811-W/en |
| //! [`x509`]: ../x509/struct.X509Builder.html |
| //! |
| //! ## Examples |
| //! |
| //! ``` |
| //! use openssl::asn1::Asn1Time; |
| //! let tomorrow = Asn1Time::days_from_now(1); |
| //! ``` |
