Java Cryptography Buffer Performance

Analysis of java cryptography performance using large buffers.

Running Locally

You may run using your preferred IDE using the main method in EncryptionBenchmark, or by executing ./gradlew run. Alternatively, you can build a zip archive using ./gradlew distZip for execution in another environment.
