`ASN.1 <https://en.wikipedia.org/wiki/ASN.1>`__ (Abstract Syntax
-Notation One) is a standard for abstract data serialization.
-`DER <https://en.wikipedia.org/wiki/Distinguished_Encoding_Rules>`__
-(Distinguished Encoding Rules) is a subset of encoding rules suitable
-and widely used in cryptography-related stuff. PyDERASN is yet another
-library for dealing with the data encoded that way. Although ASN.1 is
-written more than 30 years ago by wise Ancients (taken from ``pyasn1``'s
-README), it is still often can be seen anywhere in our life.
