Asynchronous operation mode, on the other hand, gives you flexibility and complete control over your application communications. Synchronous operation mode gives you a linear programming approach without complicated callback functions. This approach saves your development time and reduces the number of errors. Simple SecureBlackbox components can be used for reliable data transfer no matter what type of proxy or firewall is used to protect the network. You can process huge files and not be bound by restrictions of 32-bit environments. This feature works on both 32-bit and 64-bit systems without any limitations. Cryptographic hardware gains more and more popularity every day. If your software deals with X.509 certificates or PKI in general (RSA keys etc.), it is time to support cryptocards and USB tokens. SecureBlackbox was written from the ground up by EldoS Corporation developers. It doesn't use third-party code to implement its cryptographic functions. This means that you are not bound by CryptoAPI or OpenSSL version when you need to use certain algorithm.
At the same time it's possible to plug third-party security libraries and hardware modules by utilizing the pluggable architecture of SecureBlackbox. No royalties means the licensing procedure which is clear and easy to understand and manage. Pay for the license once and use it for development and deployment with no other payments. We provide free technical support via web-based Forum and HelpDesk. Support is available for everyone, and the requests from clients who purchased a license are given priority. Also you can use our extensive knowledgebase. With SecureBlackbox you can create and convert SSH keys without the need for external key management software. SSHBlackbox package includes functions that let you generate and manage SSH keys in several formats. SecureBlackbox is the only component collection that lets you build SSH servers as well as SSH clients. With the wide choice of encryption, authentication and key exchange algorithms supported by SSHBlackbox, you will be able to meet the security requirements and get compatibility with the wide choice of differently configured servers and clients. SSH and SFTP protocols offer the number of very useful features, which don't actually require TCP transport. The protocols can be used with any low-level transport protocols, and SecureBlackbox makes this possible. SSH protocol can transport many connections of different types over one secured SSH connection. Tunnels are the types of simultaneous transport that you can use. It's handy to have an SFTP tunnel used in parallel with SSH shell tunnel so that you can transfer files and operate remote system at the same time.

SecureBlackbox supports all types of tunnels, defined by SSH protocol specification. SSH protocol can transport many connections of different types over one secured SSH connection. Tunnels are the types of simultaneous transport that you can use. Ability to open and close connections on-the-fly extends your possibilities and adds flexibility to your application. SSH protocol can transport many connections of different types over one secured SSH connection. Tunnels are the types of simultaneous transport that you can use. Ability to create custom tunnel types (subsystems) extends your possibilities and adds flexibility to your application. Shell and command tunnels are used to execute commands on the remote system by using terminal / shell application (in shell tunnels) or by executing the commands directly (using command tunnels). Support for both types of tunnels adds flexibility to your application by letting you execute commands without parsing the shell prompts and extra messages or emulating a full-featured terminal. With extensive authentication support you can build multi-level authentication schemes, thus increasing security and reducing the risks when the sensitive resources are accessed.
