-<p>Pcompress is an attempt to revisit <strong>Data Compression</strong> using unique combinations of existing and some new techniques. Both high compression ratio and performance are key goals along with the ability to leverage all the cores on a multi-core CPU. It also aims to bring to the table scalable, high-throughput Global <strong>Deduplication</strong> of archival storage. The deduplication capability is also available for single-file compression modes providing capabilities that probably no other data compression utility provides. Projects like <a href="http://ck.kolivas.org/apps/lrzip/">Lrzip</a> and <a href="http://www.exdupe.com/">eXdupe</a> provide similar capabilities but do not have all of the abilities that Pcompress provides.</p>
+<p>Pcompress is an attempt to revisit <strong>Data Compression</strong> using unique combinations of existing and some new techniques. Both high compression ratio and performance are key goals along with the ability to leverage all the cores on a multi-core CPU. It also aims to bring to the table scalable, high-throughput Global <strong>Deduplication</strong> of archival storage. The deduplication capability is also available for single-file compression modes providing very interesting capabilities. Other projects providing some of these features include <a href="http://ck.kolivas.org/apps/lrzip/">Lrzip</a>, <a href="http://www.exdupe.com/">eXdupe</a>. Full archivers providing some of the similar features include the excellent <a href="http://freearc.org/">FreeArc</a> and <a href="http://peazip.sourceforge.net/">PeaZIP</a>. Pcompress is not an archiver but provides a unique combination of features to both maximize compression ratio and provide high speed.</p>
 
 <p>Pcompress can do both compression and decompression in parallel by splitting input data into chunks. It has a modular structure and includes support for multiple algorithms like LZMA, Bzip2, PPMD, etc, with SKEIN/SHA checksums for data integrity. It can also do Lempel-Ziv-Prediction pre-compression (derived from libbsc) to improve compression ratios across the board. SSE optimizations for the bundled LZMA are included. It also implements chunk-level Content-Aware Deduplication and Delta Compression features
-based on a Rabin Fingerprinting style scheme. Other open-source deduplication software like <a href="http://opendedup.org/">OpenDedup</a> and <a href="http://www.lessfs.com/wordpress/">LessFS</a> use fixed block dedupe while <a href="http://backuppc.sourceforge.net/">BackupPC</a> does file-level dedupe only (single-instance storage). Of course OpenDedup and LessFS are Fuse based filesystems doing inline dedupe while Pcompress is only meant for archival storage as of today.</p>

-<p>Delta Compression is implemented via the widely popular bsdiff algorithm. Chunk Similarity is detected using an adaptation of <a href="http://en.wikipedia.org/wiki/MinHash">MinHashing</a>. It has low metadata overhead and overlaps I/O and compression to achieve maximum parallelism. It also bundles a simple slab allocator to speed repeated allocation of similar chunks. It can work in pipe mode, reading from stdin and writing to stdout. It also provides adaptive compression modes in which some simple data heuristics are applied to select a near-optimal algorithm per chunk.</p>

 <p>Pcompress also supports encryption via AES and uses Scrypt from <a href="http://www.tarsnap.com/">Tarsnap</a> for secure Password Based Key generation.</p>
