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.
Execute ant, and you'll have the plugin ready in burp-asn1.jar
- JDK 1.7+ (tested on OpenJDK 8, Debian/Ubuntu package:
openjdk-8-jdk) - Apache ANT (Debian/Ubuntu package:
ant) - OpenSSL command line utilities (more specifically
asn1parse(1SSL), Debian/Ubuntu package:openssl)
