Post Quantum Cryptography (PQC) Liboqs algorithm facts

This article just gives an overview about the algorithm facts from the library OpenQuantumSafe liboqs-java. The values were generated during running the JUnit-tests.

For details see my article Post Quantum Cryptography (PQC) with library Liboqs overview.

Do you provide your source files to let me get the details as well?

In my GitHub repository PostQuantumCryptography with Liboqs: JavaChanges I'm providing the changed and appended files so you are been able to run this as well.

For each algorithm I created a log file with all details, get all log files in my GitHub repository PostQuantumCryptography with Liboqs: LogFiles.
