JAC (Java Asn.1 Compiler) is a tool for you if you want to (1) parse your asn.1 file (2) create .java classes of data types defined in your asn.1 file and (3) do encoding/decoding of instances of your generated classes. BER, CER and DER are a

此代码主要是 一个用JAVA实现的ASN.1的编译器，能实现正常的ASN.1的编码和解码过程，对学习ASN的同学有帮助。-This code is mainly a JAVA implementation of the ASN.1 compiler, to achieve normal ASN.1 encoding and decoding process, the students learn ASN helpful.

ASN.1开源编解码代码。ASN.1抽象语法标记（Abstract Syntax Notation One） ASN.1是一种 ISO/ITU-T 标准，描述了一种对数据进行表示、编码、传输和解码的数据格式。它提供了一整套正规的格式用于描述对象的结构，而不管语言上如何执行及这些数据的具体指代，也不用去管到底是什么样的应用程序。-ASN.1 stands for Abstract Syntax Notation One. ASN.1 allows to describe complex dat
