SecureBridge is a library of non visual components for Delphi, C++Builder, and Lazarus (Free Pascal) designed to protect network connections from unauthorized access.

SecureBridge can protect any TCP traffic using SSH or TLS/SSL protocol. These secure transport layer protocols provide authentication, strong encryption, and data integrity verification. SecureBridge can be used in conjunction with data access components to prevent data interception or modification in an untrusted network.

The SecureBridge library is actively developed and supported by the Devart Team. If you have a questions about SecureBridge, email the developers at [email protected] or visit SecureBridge online at https://www.devart.com/sbridge/.

 

Advantages of SecureBridge Library

SecureBridge is very convenient in setup and usage. It is enough to place several components on the form and specify the server address and the user login information to establish a secure connection. Applications that have to work with secure information are easy to deploy, as they do not require any external files.

Wide Support for Secure Protocols

SecureBridge supports SSH and TLS/SSL protocols, which are one of the most reliable protocols for data encryption and integrity verification. These protocols are acknowledged industry standards in the area of secure data transfer through unprotected connections.

SSH Client

SecureBridge SSH Client, that is implemented in the TScSSHClient component, can work with different SSH servers like OpenSSH, WinSSHD. It allows you achieve high performance due to connection parameters management. SSH client unites several unprotected channels from client to server in one protected connection. Logical channels can exist in different threads.

SSH Server

High-performance SSH server with wide abilities for connection setup and users management. SSH Server works with different types of SSH clients such as OpenSSH, PuTTY etc. Number of the clients connected simultaneously is limited only by system resources.

SFTP Client

SecureBridge SFTP client, that is implemented in the TScSFTPClient component, serves for secure file transfer.

SFTP Server

SecureBridge SFTP server, that is implemented in the TScSFTPServer component, serves for secure file transfer.

SSL Client

SecureBridge TLS/SSL client, that is implemented in the TScSSLClient component, can work with other applications using TLS 1.3, 1.2, 1.1, 1.0, and SSL 3.0 protocols. It allows you achieve high performance due to connection parameters management. SecureBridge does not require external units.

SSL Server

SecureBridge TLS/SSL server, that is implemented in the TScSSLServer and the TScSSLServerConnection components, can work with different types of TLS/SSL clients using TLS 1.3, 1.2, 1.1, 1.0, and SSL 3.0 protocols. SecureBridge does not require external units.

FTPS Client

SecureBridge FTP/FTPS client, that is implemented in the TScFTPClient component, serves for secure file transfer.

HTTP/HTTPS Server

SecureBridge HTTP/HTTPS server, that is implemented in the TScHttpServer component, supports request/response model for accessing data from a Web server by the HTTP protocol.

HTTP/HTTPS Client

SecureBridge HTTP/HTTPS client, that is implemented in the TScHttpWebRequest component and the TScHttpWebResponse class, supports request/response model for accessing data from a Web server by the HTTP protocol.

WebSocket Client

SecureBridge WebSocket client, that is implemented in the TScWebSocketClient component, serves for accessing data from a Web server by the WebSocket protocol.

SignalR Client

SecureBridge SignalR client, that is implemented in the TScHubConnection component, serves for connection with a hub server.

SMTP/SMTPS Client

SecureBridge SMTP/SMTPS client, that is implemented in the TScSMTPClient component, serves for sending email messages to recipients using the SMTP server.

REST compatibility

SecureBridge allows to create REST applications using the TScHttpWebRequest component.

 

Protection Against Diverse Attacks

SecureBridge protects transferred data against different kinds of attacks. SecureBridge uses the Diffie-Hellman key exchange algorithm for connection establishing. A reliable random number generator is used for keys generating. To protect data against illegal access, information is encrypted by symmetric algorithms that provide high speed and reliability. For data integrity verification hash algorithms like SHA2 are used.

 

Support for CMS format to encrypt and sign data

The TScCMSProcessor component implements the Cryptographic Message Syntax (CMS) - syntax for data protection. It supports digital signatures and encryption.

 

Support for Third Party Components

SecureBridge supports Internet Direct components (Indy), MySQL Data Access Components (MyDAC) and PostgreSQL Data Access Components (PgDAC). This allows you to implement all the advantages of the encrypted connection within a single application without any external files.
