1RSA OAEP SHA2 vector creation 2============================= 3 4This page documents the code that was used to generate the RSA OAEP SHA2 5test vectors as well as code used to verify them against another 6implementation. 7 8 9Creation 10-------- 11 12``cryptography`` was modified to allow the use of SHA2 in OAEP encryption. Then 13the following python script was run to generate the vector files. 14 15.. literalinclude:: /development/custom-vectors/rsa-oaep-sha2/generate_rsa_oaep_sha2.py 16 17Download link: :download:`generate_rsa_oaep_sha2.py 18</development/custom-vectors/rsa-oaep-sha2/generate_rsa_oaep_sha2.py>` 19 20 21Verification 22------------ 23 24A Java 8 program was written using `Bouncy Castle`_ to load and verify the test 25vectors. 26 27 28.. literalinclude:: /development/custom-vectors/rsa-oaep-sha2/VerifyRSAOAEPSHA2.java 29 30Download link: :download:`VerifyRSAOAEPSHA2.java 31</development/custom-vectors/rsa-oaep-sha2/VerifyRSAOAEPSHA2.java>` 32 33Using the Verifier 34------------------ 35 36Download and install the `Java 8 SDK`_. Initial verification was performed 37using ``jdk-8u77-macosx-x64.dmg``. 38 39Download the latest `Bouncy Castle`_ JAR. Initial verification was performed 40using ``bcprov-jdk15on-154.jar``. 41 42Set the ``-classpath`` to include the Bouncy Castle jar and the path to 43``VerifyRSAOAEPSHA2.java`` and compile the program. 44 45.. code-block:: console 46 47 $ javac -classpath ~/Downloads/bcprov-jdk15on-154.jar:./ VerifyRSAOAEPSHA2.java 48 49Finally, run the program with the path to the SHA-2 vectors: 50 51.. code-block:: console 52 53 $ java -classpath ~/Downloads/bcprov-jdk15on-154.jar:./ VerifyRSAOAEPSHA2 54 55.. _`Bouncy Castle`: https://www.bouncycastle.org/ 56.. _`Java 8 SDK`: https://www.oracle.com/technetwork/java/javase/downloads/index.html 57
