JAR files are ZIP-compatible. You can rename the extension from .jar to .zip and extract the contents to view the structure, class files, and manifest.
It is not possible to provide the specific content of "obf-jar-id-353911.jar-out.jar" without access to the file itself, as this appears to be a unique, obfuscated, and likely renamed Java archive (JAR) file. obf-jar-id-353911.jar-out.jar
Knowing the context helps me guide you on the best analysis tools. JAR files are ZIP-compatible
