ASN.1阅读材料

Question

Is there any place where i could get some materials to know about ASN.1. I want to know about the syntax's to be used and also some examples to get some overview.

Any help is appreciated.

Answer 1

There are a few more or less free documents on ASN.1.

A good short intro is A Layman's Guide to a Subset of ASN.1, BER, and DER , especially if you need it in the context of X.509 or similar stuff.

Another good resource would be the book from Olivier Dubuisson which can be downloaded after a free of charge registration from: ASN.1 Reference Book , another book there is from John Larmouth ASN.1 Complete , might also be worth a look.

You can also go in depth with the appropriate standards documents from the ISO, but those tend to be rather cryptic, you can find all the references at wikipedia http://en.wikipedia.org/wiki/Abstract_Syntax_Notation_One#References

Answer 2

我发现ASN1C文档和示例在过去非常有用。

Answer 3

It would be good to start at A Layman's Guide to a Subset of ASN.1 but if you have some konwledge on asn1 syntax then for practice or understanding you can make some sample on http://asn1-playground.oss.com/
