ASN.1 toolbox for Burp Suite

Right now, this is just a proof of concept which decodes Base-64 encoded SEQUENCE objects and pipes them through OpenSSL's asn1parse with some usability improvements like automatically diving into appl entries and formatting hex dumps producing an output that mimics hd.

In the future, I plan on having an editor, native java codec and insertion points for the Scanner module to use.

Building

Execute ant, and you'll have the plugin ready in burp-asn1.jar

Dependencies
