CryptoPressStream is a streaming compression and encryption library. 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 such as progress event, LoadFromStream, LoadFromFile, SaveToStream, SaveToFile methods, Lock and Unlock methods for multi-thread usage. CryptoPressStream includes TCPSManager thread-safe component that provides easy settings of compression and encryption parameters, and contains a list of opened streams.

CryptoPressStream contains TCPSManager visual component, Component Reference, 7 demos, License Agreement in License.txt file, History Of Changes in History.txt file and general information in ReadMe.txt file.
