Compression-Decompression algorithm

I have a computer (not a PC) that has a routine to compress-Uncompress data. I don't have the source of the program but I need to develop a routine in Windows able to compress-decompress data with the same algorithm. I can provide as many examples of compressed-decompressed strem as needed to discover the logic of the algorithm and then develop a corresponding equal algorithm on the PC side The pc program can be written in any language but must be the fastest possible and must be provided as a dll receiving a byte stream and producing the compression/decompression I include an example of compressed output ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform Windows (all 32 bit versions)
