• JarProtector is the most secure way to protect your java class files and resources from decompilation.

  • JarProtector completely encrypts your jar files into car files, which can be distributed to your customers.

  • The encrypted car files are inaccessible, so class and resource files are protected from extracting and decompiling.

  • JarStarter (part of JarProtector) lets you start java software containing car files in classpath.

  • Classes and resources will be created during runtime directly in native JVM without calling defineClass().

  • JarProtector runs in JRE 1.6, 1.7, 1.8, 1.9 on Microsoft┬« Windows XP/7/8/10, Mac OS X/maxOS and Linux┬«. JarProtector is not being developed anymore.
