CryptographicMechanisms.Labs

Getting Started

There are three conditions in which this application can be run:

• Get test execution results for predefined values:

java -jar labs-1.3-SNAPSHOT-jar-with-dependencies.jar

• Execute multiplication operation for your own input parameters in hex interpretation:

java -jar labs-1.3-SNAPSHOT-jar-with-dependencies.jar <First input>  * <Second input>

• Generate comparison statistics for developed LongNumber and built-in BigInteger operations using randomly generated inputs (size: 768 and 1024 bits):

java -jar labs-1.3-SNAPSHOT-jar-with-dependencies.jar Statistics

Prerequisites

You need to use installation steps from here and download "labs-1.3-SNAPSHOT-jar-with-dependencies.jar" file from CryptographicMechanisms.Labs/target/ folder.
