The full list of new and improved features in this release:

  • macOS 64-bit is supported
  • Lazarus 2.0.4 is supported
  • Support for the SignalR protocol version 2.2 is added
  • The TScHubConnection component to support the SignalR client is added
  • Support for the x25519 algorithm for the TLS/SSL/SSH protocol is added
  • Support for Certificate Revocation List (CRL) is added
  • Certificate server validation in the TLS/SSL protocol is improved
  • The chunked transfer encoding for sending out data via HTTP/HTTPS is added
  • The TScHttpWebRequest.BeforeSendData event is added

x25519 Key Exchange

x25519 is an elliptic Diffie-Hellman key exchange algorithm using Curve25519. It allows a TLS/SSL/SSH client and a server to agree on a shared secret over an insecure channel.

Certificate Revocation List

A Certificate Revocation List (CRL) is a list of digital certificates that have been revoked by the issuing Certificate Authority (CA) before their expiration date. SecureBridge now verifies whether a certificate is valid and trustworthy.


SignalR is a protocol that makes it easier to add real-time web functionality to apps. It lets server-side code push content to connected clients in real time without waiting for the clients to request data. SignalR uses hubs to communicate between clients and servers. We added the TScHubConnection component to SecureBridge to support this communication protocol.

SecureBridge Features

SecureBridge offers components that can be used as clients and servers for SSH, SFTP, SSL, FTPS, HTTP/HTTPS, WebSocket, and SignalR protocols to protect data flow over an untrusted network. SecureBridge are compatible with data access components to prevent data interception and theft. To establish a secure connection, you only need to put a few components onto the form and specify server address and client credentials.
