JCE DES Operation Mode Testing Program Result
This section provides testing results of a tutorial example program to test DES operation modes implemented in the JDK JCE package.
I used my testing program, JceSunDesOperationModeTest.java, to test the cases listed in the http://www.itl.nist.gov/fipspubs/fip81.htm:
herong> javac JceSunDesOperationModeTest.java herong> echo Test with ECB herong> java JceSunDesOperationModeTest 1 Key : 0123456789ABCDEF Message : 4E6F77206973207468652074696D6520666F7220616C6C20 Cipher : 3FA40E8A984D48156A271787AB8883F9893D51EC4B563B53 Expected: 3FA40E8A984D43156A271787AB8883F9893D51EC4B563B53 herong> echo Test with CBC herong> java JceSunDesOperationModeTest 2 Key : 0123456789ABCDEF IV : 1234567890ABCDEF Message : 4E6F77206973207468652074696D6520666F7220616C6C20 Cipher : E5C7CDDE872BF27C43E934008C389C0F683788499A7C05F6 Expected: E5C7CDDE872BF27C43E934008C389C0F683788499A7C05F6 herong> echo Test with CFB herong> java JceSunDesOperationModeTest 3 Key : 0123456789ABCDEF IV : 1234567890ABCDEF Message : 4E6F77206973207468652074696D6520666F7220616C6C20 Cipher : F3096249C7F46E51A69E839B1A92F78403467133898EA622 Expected: F3096249C7F46E51A69E839B1A92F78403467133898EA622 herong> echo Test with OFB herong> java JceSunDesOperationModeTest 4 Key : 0123456789ABCDEF IV : 1234567890ABCDEF Message : 4E6F77206973207468652074696D6520666F7220616C6C20 Cipher : F3096249C7F46E5135F24A242EEB3D3F3D6D5BE3255AF8C3 Expected: F3096249C7F46E5135F24A242EEB3D3F3D6D5BE3255AF8C3
Outputs of the first 3 test cases match well with the expected values documented in http://www.itl.nist.gov/fipspubs/fip81.htm. The output of the last test case can not be compared, since it is not documented in FIPS 81.
