CryptoPressStream is a streaming compression and encryption library for Delphi and C++ Builder. It provides transparent access to compressed or encrypted data stored in the stream object. All stream objects are 100% compatible with TStream and have some advanced functionality like progress event, LoadFromStream, LoadFromFile, SaveToStream, SaveToFile methods, Lock and Unlock methods for multi-thread usage. CryptoPressStream includes TCPSManager thread-safe component that provides an easiest setting of compression and encryption parameters, and contains a list of opened streams. 

• Transparent streaming compression and encryption library with 100 % TStream compatibility.
• Forward and backward seeks to any position, partial rewriting of the stream, read cache.
• Support for large 64-bit streams (> 2 Gb).
• Compression and encryption component supporting buffers, strings, files.
• 3 data compression algorithms: ZLIB, BZIP, PPM.
• Strong customizable encryption with binary key support (12 algorithms and 4 modes): Rijndael (AES) 128 and 256, Blowfish, Twofish 128 and 256, DES single, double and tripple, Square.
• TCPSManager component for compression and encryption settings, list of opened stream, memory leaks prevention.
• Native VCL, does not require any DLLs.
