FlexCompress is a high-speed compression library developed to provide archive functionality for your applications. This solution provides flexible compression and strong encryption algorithms that allows you to integrate archiving or backup features into your programs in a fast and easy way. FlexCompress includes our new unique technology, a transaction system. This innovative solution gives you a rapid and simple way of updating archive files providing data integrity like a reliable database system.

Features
Compression and encryption algorithms
Wide range of compression algorithms: ZLib, BZip and PPM with different compression levels
Creates encrypted archives using strong encryption algorithms: Rijndael 128 and 256 bit version, Advanced Encryption Standard (AES) winner, DES Single and Tripple, Blowfish 256 bit, Twofish 128 and 256 bit, Square 128 bit, hash RipeMD-128 and RipeMD-256
Fastest compression levels are extremely fast
Good balanced compression levels provide both good compression rate and high speed
Maximum compression levels provide much better compression rate than Zip, RAR and BZIP
Speed
Special tuning for compression algorithms implementations
One of the fastest Deflate implementations available today
Transaction system optimizing a group of archive modifications
Functionality
Adds, moves, extracts, deletes, updates, tests, refreshes a group of files by a single operation
Supports in-memory archives
Stores archives in TStream descendant objects like BLOB streams
