BigSpeed File Sharing SDK  Downloads: | Views:

BigSpeed File Sharing SDK includes two ActiveX controls (client and server) that dramatically simplify and accelerate the development of private file sharing solutions over the Internet. In addition to standard FTP operations, such as upload, download, rename, delete, etc., the library also offers a number of advanced features which give the local application full control over the remote files. The client is able to open seekable streams on the server, either in read-only or read-write access mode. The application can seek, read, an write bytes to the stream as it is a local file. The client is able to run search operation on the server. The searching criteria may include file name masks (wildcards), text strings inside the files, or both of them. The found items are reported in real-time, while the operation is running. The server is able to perform remote file compression and decompression by a request from the client. During zipping or unzipping detailed progress information is provided back to the client about the current and total file and byte counts. The transfered data are scrambled using on-the-fly 128-bit AES encryption, without need of SSL certificates. The security is provided in two different modes: symmetric encryption with shared secret key and asymmetric encryptionwith 1024-bit public/private keys. There is an option to compress on-the-fly the outgoing data before encrypting, which may reduce greatly the transfer time for large files. BigSpeed File Sharing SDK utilizes an elegant event-driven paradigm for easy integration into Windows applications. A special attention is paid to provide responsive user interface while maintaining maximum bandwidth efficiency. Carefully designed set of properties, methods, and events offers great flexibility to develop innovative communication software. Sample applications are included in Visual Basic 6, Visual Basic .NET, Visual C++ .NET, and Delphi 7. Main Features:   All standard FTP operations - download, upload, rename, delete, etc.   Open/seek and read/write bytes from/to seeakable streams   Remote file ant full text search   Remote file compression to zip archives   Remote file decompression from zip archives   On-the-fly 128-bit AES encryption with random session keys   Symmetric encryption mode with shared secret key   Asymmetric encryption mode with 1024-bit Public/Private keys   Protocol level authentication with digital fingerprints or secret keys   Transparent data compression (Deflate algorithm)   Centralized management of all connections (server)   Automatic DNS name resolution (client)   SOCKS proxy support (client)   Elegant event-driven paradigm for easy integration into Windows applications   Responsive user interface while maintaining maximum bandwidth   Simple and well-organized set of properties, methods and events   Multi-threaded, fully self-contained ActiveX control
