• SSH channel encryption. SecureBridge implements the SSH protocol to create secure tunnels. It establishes encrypted connections between client and server. The encryption applies cryptographic algorithms to the entire data stream. The transmission remains protected against network interception.
• Public key authentication. The component supports authentication methods based on RSA and DSA keys. It verifies the identity of the parties without transmitting passwords. The system uses digital certificates to authorize connections. This method eliminates risks associated with weak passwords.
• Secure SFTP file transfer. SecureBridge includes SFTP clients and servers. It allows file operations over existing SSH channels. The transfers maintain data integrity and confidentiality. Supports standard operations such as download, upload, and directory listing.
• Secure SSH terminal. The component emulates a remote terminal session. It executes commands on remote systems through an encrypted connection. Provides a secure environment for server administration. Transmits command input and output via SSH tunnel.
• Telnet server and client. SecureBridge offers an implementation of the Telnet protocol. It is used for unencrypted network connections where security is not critical. Includes virtual terminal capabilities for system interaction. Supports basic username and password authentication.
• SSL/TLS data encryption. The library incorporates SSL and TLS protocols for custom applications. Adds encryption to any existing TCP/IP connection. Implements cryptographic handshake and parameter negotiation. Protects against eavesdropping and data modification in transit.
• X.509 certificate generation. SecureBridge includes tools to create and manage digital certificates. Generates public and private keys for party identification. Certificates follow the X.509 standard for interoperability. They facilitate the implementation of public key infrastructures.
• Real-time data compression. The component applies compression algorithms to data streams. Reduces bandwidth used during transmissions. Implements compression before encryption for greater efficiency. Supports multiple configurable compression methods.
• Detailed operation logging. SecureBridge provides an extensive logging system. Logs connection, authentication, and transfer events. Logs aid in auditing and troubleshooting. Configures detail levels according to security requirements.
• Multi-factor authentication. The component supports a combination of authentication methods. Allows requiring both password and public key for access. Increases security through multi-stage verification. Integrates with existing authentication systems.
• Centralized key management. SecureBridge offers secure storage for cryptographic keys. Organizes certificates and private keys in structured repositories. Simplifies credential management for multiple connections. Supports standard formats such as PKCS#12.
• Configurable cryptographic algorithms. The library allows selecting specific encryption algorithms. Includes options like AES, Blowfish, 3DES, and RC4. Configures key length and operation modes. Allows adaptation to organizational security policies.

SecureBridge was developed by Devart. Development began in 2004. The first version was released in 2005. The components are written in Delphi and C++Builder. The development team maintains periodic updates. The solution has evolved with security standards.
