Java Obfuscator

The java-tool.jar can be used both for obfuscating a folder of files (folder mode) or splitting (into its methods) and obfuscating an individual .java file (file mode)

Folder Mode

Provide args:

• -s - Source directory of java files
• -t - Target directory for obfuscated files
• -pNum - Partition number we are currently in (i.e. 1, 2, 3, ... up to pTotal)
• -pTotal - Total number of partitions (e.g. 4: partition the folder of files into 4 parts)
• -threads - How many threads to use for the processing
• -r - Optional flag, obfuscate the files using Random obfuscation (default uses type obfuscation)

The obfs-script.sh script is the recommended way to use the tool, change the appropriate variables to suit your system and run the script file

File Mode

In this mode, the script reads in a single file, applies some obfuscation (if any), then prints to standard out each individual method, delineated by _METHOD_SPLIT_. This output can then easily be parsed to get a list of all methods in a file.

Args:

• -o - Type (O)bfuscation
• -r - (R)andom obfuscation
