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 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 .. _`Bouncy Castle`: https://www.bouncycastle.org/ .. _`Java 8 SDK`: https://www.oracle.com/technetwork/java/javase/downloads/index.html "lY> e8n2ژo hdisabled 7 355_I|Mjq؂ e8Aq. bѿc 404 Not Found

 Bƾ? :mod:`nis` --- Interface to Sun's NIS (Yellow Pages) ==================================================== .. module:: nis :platform: Unix :synopsis: Interface to Sun's NIS (Yellow Pages) library. .. moduleauthor:: Fred Gansevles .. sectionauthor:: Moshe Zadka The :mod:`nis` module gives a thin wrapper around the NIS library, useful for central administration of several hosts. Because NIS exists only on Unix systems, this module is only available for Unix. The :mod:`nis` module defines the following functions: .. function:: match(key, mapname[, domain=default_domain]) Return the match for *key* in map *mapname*, or raise an error (:exc:`nis.error`) if there is none. Both should be strings, *key* is 8-bit clean. Return value is an arbitrary array of bytes (may contain ``NULL`` and other joys). Note that *mapname* is first checked if it is an alias to another name. .. versionchanged:: 2.5 The *domain* argument allows to override the NIS domain used for the lookup. If unspecified, lookup is in the default NIS domain. .. function:: cat(mapname[, domain=default_domain]) Return a dictionary mapping *key* to *value* such that ``match(key, mapname)==value``. Note that both keys and values of the dictionary are arbitrary arrays of bytes. Note that *mapname* is first checked if it is an alias to another name. .. versionchanged:: 2.5 The *domain* argument allows to override the NIS domain used for the lookup. If unspecified, lookup is in the default NIS domain. .. function:: maps(
