asn-one - ASN.1 library for Java

What is asn-one

asn-one is a pure Java implementation of an ASN.1 encoder and decoder. It supports the BER and DER encoding rules of the bytestream. It is designed to be as lightweight as possible by having minimized the external dependencies. It only depends on the SLF4J logging API.

Getting asn-one

To get asn-one, you have two options:

1. Add a dependency to asn-one to your project.

2. Build asn-one yourself.

Binary releases of asn-one are not provided here, but you can download it straight from the Maven Central repository if you want to.

Depending on asn-one

If you’re building your project using Maven, you can add the following dependency to the pom.xml:

<dependency>
  <groupId>com.hierynomus</groupId>
  <artifactId>asn-one</artifactId>
  <version>0.7.0</version>
</dependency>

If your project is built using another build tool that uses the Maven Central repository, translate this dependency into the format used by your build tool.

Building asn-one

1. Clone the asn-one repository.

2. Run the command ./gradlew clean build.
