RSA OAEP SHA2 vector creation
|
|
=============================
|
|
|
|
This page documents the code that was used to generate the RSA OAEP SHA2
|
|
test vectors as well as code used to verify them against another
|
|
implementation.
|
|
|
|
|
|
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
|
|
</development/custom-vectors/rsa-oaep-sha2/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
|
|
</development/custom-vectors/rsa-oaep-sha2/VerifyRSAOAEPSHA2.java>`
|
|
|
|
Using the Verifier
|
|
------------------
|
|
|
|
Download and install the `Java 8 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
