Jenny, (alt. spelling J[e]ni), found a nice Java program to reverse engineer. It's Java, so it's easy to reverse engineer, right (since there's a lot of decompilers out there)? Prove to her that this is easy -- or hard -- good luck! https://mega.nz/#!2WoRzaZY!NH8XQ1_qbp1ZOrknng198nLvR6dMC6eDIQs1TlRi3pY

    Here's a big fat HINT: when I wrote this challenge, it was on Java 8 (so probably use that to run it ;) There will be multiple valid passwords, but only one of them make sense!

      Are you able to tell an exact version of JVM that this challenge works with? I'm interested in version number and vendor (oracle JVM / opejdk...)

      • thekidofarcrania moderator badge

        Keep in mind the date of when this challenge was written :)

        I don't actually remember the exact JVM version, I think when I wrote it it was using openjdk, but I recently tested and it works in the latest version of openJDK 8

        • nza777

          Oh, the information that it was openjdk is enough for me. I was using oracle jdk, what could have been a point of failure. Thank you for info.

    It is getting difficult to obtain the version of OpenSSL this is compiled for. Can a link be provided to the exact binary so that is not the stumbling block?

    This challenge has been tested under a ubuntu18.04 machine (using Java 8)
