mts-asn1 is a multi-platform project written in JAVA. It aims to use protocols described in ASN.1 PER. In order to do that, it allows you to write your data in various format (JSON, XML, ...).

How to use it ?

• Create a new ASN1Translator which take ASN.1 encoding and the grammar in parameters

Example :

• Invoke decode or encode on it with proper parameter and your chosen dataformat

Example :
XMLFormatWriter formatWriter = new XMLFormatWriter(); asn1Translator.decode(type, this.getClass().getResourceAsStream(binaryPath), formatWriter);

or

JSONFormatReader jsonFormatReader = new JSONFormatReader(this.getClass().getResourceAsStream(expectedJsonPath), type); BitArray bitArray = new BitArray(); asn1Translator.encode(type, bitArray, jsonFormatReader);

If you want to test a single binary message, you may want to convert your hexadecimal file to a binary file using a converter (example : here).
