[MS-XCA]: Xpress Compression Algorithm

Specifies the three variants of the Xpress Compression Algorithm: LZ77+Huffman, Plain LZ77, LZNT1, and their respective decompression algorithms. This algorithm efficiently compresses data that contains repeated byte sequences. It is not designed to compress image, audio, or video data. Between the trade-offs of compressed size and CPU cost, it heavily emphasizes low CPU cost.
