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.
