BigSpeed Secure Socket Library 2.0
BigSpeed Secure Socket Library is an ActiveX control that dramatically simplifies and accelerates the development of proprietary communication solutions over the Internet. It implements a flexible message-oriented protocol on top of a single TCP connection. The transfered data are scrambled using on-the-fly 128-bit AES encryption with random session keys, without need of SSL certificates. The security is provided in two different modes: symmetric encryption with shared secret key and asymmetric encryption with 1024-bit public/private keys. Transport level authentication is available with optional digital fingerprints or secret keys. Building a virtual private application network is just a matter of setting the same crypto key on two or more sites. BigSpeed Secure Socket Library can be used both on client and server side, with centralized management of all connections. Information is exchanged through typed data packets identified by a command code. The library takes care of all low-level tasks: packetizing/depacketizing, compression/decompression, encryption/decryption, sending, receiving, buffer congestion and flow control. There is support for automatic DNS name resolution and SOCKS proxy servers. BigSpeed Secure Socket Library 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 for chat, alert messaging, and file transfer are included in Visual Basic 6, Visual Basic .NET, Visual C++ .NET, and Delphi 7.
BigSpeed File Sharing SDK 2.0
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 Zipper 4.1
BigSpeed Zipper is a .zip format compression utility. Being simple and intuitive to use with its explorer-style interface, it boasts a large number of features the other utilities on the market do not have. The most notable one is the ability to extract files from archives on remote servers without having to download the archive.The possibilities given by this and other features change the whole concept of an archive utility. BigSpeed Zipper also allows you to search in all zip files on the disk for specified files or text inside them, view the contents of zip files while downloading them, automate frequently used compression operations, backup files in zip format to disk or FTP server, upload zip files to FTP servers, send zip files as email attachments, synchronize the contents of zip files and folders, split/join files to/from smaller chunks, repair damaged zip files, create self-extracting packages, create multiple volume zip archives (including on non removable drives). And even this isn`t all this program can do. If you require maximum functionality from a .zip utility, make this one your first choice. It`s free, by the way!
BigSpeed Peer-to-Peer SDK 1.0
BigSpeed Peer-to-Peer SDK is a set of two COM components (Agent and Hub) that lets you set up a virtual private peer-to-peer (P2P) network for secure file sharing and messaging. The transfered data are scrambled using on-the-fly 128-bit AES encryption, without need of SSL certificates. NAT traversal is implemented by using TCP hole-punching technology. The security is provided in two different modes: symmetric encryption with shared secret key and asymmetric encryption with 1024-bit public/private keys. The hub is responsible for keeping information on and authentication of online peers. All peers connected to a particular hub build a single private community. Each agent acts as both a client and a server at the same time. Fine grained access control is realized by a user-oriented permissions. They grant access control privileges to system resources and services in a flexible and secure manner. Two different kind of instant information can be exchanged between peers: alert and chat messages. In addition to standard FTP operations, such as upload, download, rename, delete, etc., the SDK also offers several advanced features. The broken file transfers are resumed automatically (if enabled), with MD5 integrity checking. The agent is able to run search operation on the peers. The server module is able to perform file compression and decompression by a request from the remote client module. 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 Peer-to-Peer SDK utilizes an elegant event-driven paradigm for easy integration into Windows applications. A special attention is paid to provide responsive user interface while avoiding multithreading problems and maintaining maximum bandwidth efficiency. Sample applications are included in VB .NET, VB 2005 and Delphi 7.
