My hobbyist coding updates and releases as the mysterious "Mr. Tines"

Smelling the coffee…

… before work goes crazy in the 4 weeks left to holidays — a first drop of; what may (ha! ha!) become a hybrid Java/Ruby CTClib equivalent for both JVM and CLR.

This contains code for various symmetric crypto algorithms, strong hashes, erasable big numbers and Zlib compression (based on JZlib 1.0.7); it contains some initial JUnit tests aimed at JUnit 3.8.2 in NetBeans 6.0 (currently using RC1). It also contains a project to build JUnit 3.8.2 (almost) as a J# project generating a command line executable (.exe also included). The "almost" is because the assertEquals() methods for Double and boolean have been taken from 3.8.1 to permit them to compile under J#.

The NetBeans project has been amended to use cobertura 1.9 to perform coverage analysis as the unit tests are run -- assumed to be in C:\cobertura-1.9, adjust build.xml to fit your location; or use it as a prototype for other projects. The VS 2005 solution builds the JUnit ~3.8.2 executable, the angerona.algorithms.dll library, and the unit tests as three projects; and as a post-build step for the last runs the tests under NCover (assumed to be installed to directory C:\Program Files\NCover) -- I'm using 1.5.4, having had some problems with 1.5.8 run over managed C++ code not contained in gc classes.

Also included is an FxCop project; I shall be using that run manually, and PMD as a live plug-in while the code is being groomed; they will get incorporated into the build process later when the noise level has been considerably reduced.

Note that the two build environments are set up to use the same source file structures, though J# has to be hand-held to point it at the files that NetBeans just picks up automagically.

The only files in any sort of stable state at the moment, the proofs of concept, are and, which have unit tests based on the FIPS PUB 180-1 test vectors. These tests all pass and give 100% coverage (including branch coverage) to the base SHA class and the two wrappers. The first phase will be getting the state of no PMD warnings, no FxCop warnings (except where naming conventions are involved, and there, Java conventions set out by PMD will win if there is a conflict), unit tests with ideally 100% coverage; this will overlap with doing some refactoring.

Then with a stable foundation, the plan will be to gradually migrate the rest of CTClib, primarily to Ruby, but probably with a few Java interface types to make the external interface more easily usable by other JVM or CLR projects.
