是否有用于BER-TLV的Java解析器? [英] Is there a Java parser for BER-TLV?

问题描述

我是Java的新手，所以我想将标准解决方案用于标准任务.标签和值的长度未知.

I'm new to Java, so I would like to use the standard solution for, I think, the standard task. The length of tags and values ​​are not known.

推荐答案

您可以使用以下BER-TLV解析器:

You can use this BER-TLV parser: source code on git.
Examples:

How to parse

byte[] bytes = HexUtil.parseHex("50045649534157131000023100000033D44122011003400000481F");
BerTlvParser parser = new BerTlvParser(LOG);
BerTlvs tlvs = parser.parse(bytes, 0, bytes.length);

如何构建

byte[] bytes =  new BerTlvBuilder()
                .addHex(new BerTag(0x50), "56495341")
                .addHex(new BerTag(0x57), "1000023100000033D44122011003400000481F")
                .buildArray();
