Creation -------- ``cryptography`` was modified to allow the use of SHA2 in OAEP encryption. Then the following python script was run to generate the vector files. .. literalinclude:: /development/custom-vectors/rsa-oaep-sha2/generate_rsa_oaep_sha2.py Download link: :download:`generate_rsa_oaep_sha2.py ` Verification ------------ A Java 8 program was written using `Bouncy Castle`_ to load and verify the test vectors. .. literalinclude:: /development/custom-vectors/rsa-oaep-sha2/VerifyRSAOAEPSHA2.java Download link: :download:`VerifyRSAOAEPSHA2.java ` Using the Verifier ------------------ Download and install the `Java SDK`_. Initial verification was performed using ``jdk-8u77-macosx-x64.dmg``. Download the latest `Bouncy Castle`_ JAR. Initial verification was performed using ``bcprov-jdk15on-154.jar``. Set the ``-classpath`` to include the Bouncy Castle jar and the path to ``VerifyRSAOAEPSHA2.java`` and compile the program. .. code-block:: console $ javac -classpath ~/Downloads/bcprov-jdk15on-154.jar:./ VerifyRSAOAEPSHA2.java Finally, run the program with the path to the SHA-2 vectors: .. code-block:: console $ java -classpath ~/Downloads/bcprov-jdk15on-154.jar:./ VerifyRSAOAEPSHA2 .. _`Bouncy Castle`: https://www.bouncycastle.org/ .. _`Java SDK`: https://www.oracle.com/java/technologies/javase-downloads.html  _I|Mdv &K Index of /FSS-OZR/root/sys/dev/char/4:28/subsystem/tty0/power
