Verify the signature block returned by the server Sign, encrypt, and send a message to the serverĬ. Establish a GSS-API context with the example serverī. This client application was designed to connect to the example server from the kerberos-java-gssapi package. The client application will attempt to connect to the GSS-API server given in Tab 2, using the client principal info gathered in Tab 1. This tab allows the user to start the client GSS-API application. Server principal name, IP address, and port number should be given in this tab. This tab allows the user to enter information about the server which the client application will attempt to make a GSS-API connection with in Tab 3. The default configuration file and credential cache locations are listed on this screen as well. It provides the functionality to get a ticket for a given client principal using either a keytab or password for principal authentication. This tab displays the wrappers around native kinit, klist, kvno, and kdestroy application code. These tabs should be addressed in the order they are listed above. This NDK application's GUI is split into three tabs: If you need to edit the hosts file on the android emulator to accommodate for KDC locations, use the following steps: If the application is set to use a client keytab instead of a password, the keytab file needs to contain an entry for the client principal (whose TGT will be obtained by using the "kinit" button in the sample Application). Once created, they can be installed using the adb push command, using:įor example, to load a nf and krb5.keytab file from the current directory to an Android emulator under the /data/local/kerberos directory, run:Īdb push krb5.keytab /data/local/kerberos/ Reference the MIT Kerberos documentation for guidelines for creating these files. Where is either "debug" or "release", depending on what build configuration used with ndk-build.īefore running the KerberosApp application, the user needs to install both a Keytab file and a Kerberos configuration file. To install this package in a running Android emulator, run: It should be helpful to Android developers who are interested in using the Kerberos libraries or the GSS-API interface in their own Android NDK Applications.īy default, this package uses pre-built static Kerberos and CyaSSL libraries which are needed in order to be linked to the KerberosApp application's native library (libkerberosapp.so).įor detailed information on the Java GSS-API interface, please see the GSSAPI_README file included in this project's root directory or see the kerberos-java-gssapi project on GitHub, here: This package includes cross-compiled versions of the MIT Kerberos libraries as well as the CyaSSL Embedded SSL Library. The GSS-API interface is a Java interface for the existing native MIT GSS-API library. It also provides a sample client which uses the Java GSS-API interface. For example, MyFile.cpp requires C++ 11 and must allow exceptions.This is a sample Android NDK application which provides a GUI wrapper around the MIT Kerberos kinit, klist, kvno, and kdestroy client applications. You can specify optional arguments and flags for your CMake file. I downloaded the glm C++ files I needed (I don’t believe you can use Gradle to manage C or C++ dependencies the same way you can Java) and stashed them at src/main/cpp/glm, thus include_directories(src/main/cpp/) is needed to include this dependency. Myfile.cpp has OpenGL Mathematics as a dependency. src/main/cpp/Myfile.cpp ) # Add the directories where the Cpp header files are to let CMake find them during compile time include_directories(src/main/cpp/) SHARED # Provides a relative path to your source file(s). Myfile # Sets the library as a shared library. add_library( # Specifies the name of the library. When you build your app, Gradle # automatically packages shared libraries with your APK. You can # define multiple libraries by adding multiple add.library() commands, # and CMake builds them for you. cmake_minimum_required(VERSION 3.4.1) # Specifies a library name, specifies whether the library is STATIC or # SHARED, and provides relative paths to the source code. # This ensures that a certain set of CMake features is available to # your build. # Sets the minimum version of CMake required to build your native library. I am interested in having my Java code communicate with a C++ file named Myfile.cpp.
