By default the TsgcHTTP1client uses blocking requests, so after calling an HTTP Request method, the client waits the response from the server. From sgcWebSockets 2025.3.0 you can use Asynchronous methods to execute these HTTP Requests in a secondary thread avoiding to block the thread where the requests is called. The following asynchronous methods...

By Default Indy defines the most common openssl functions needed to encrypt the communications, but sometimes you need more functions for encryption, signing... From sgcIndy 2025.3.0 you can use the new method IdOpenSSLSetLoadFuncsCallback to assign a callback for loading additional OpenSSL functions dynamically. IdOpenSSLSetLoadFuncsCall...

The OpenAI Assistant Client has been improved to implement the streaming responses when calling a run thread. Before this new feature, it requires to poll the run object status till it's completed. Now you can use the new Stream events to handle the streaming messages. Streaming Events Instead of waiting the full response from the assistant, y...

From sgcWebSockets 2024.10.0 you can use the OpenAI Assistants to search in your own files instead of using the generic model. File Search augments the Assistant with knowledge from outside its model, such as proprietary product information or documents provided by your users. OpenAI automatically parses and chunks your documents, creates and store...

From sgcOpenAPI 2024.9.0 the parser has been improved with the following new features: - Bundle Specification: if the specification is built with multiple schemas, the parser can bundle into a single specification file. - Output Parser Parameters: when creating the pascal interface, the parameters used to import the specifications are written in th...

OpenSSL 3.0 moved several deprecated or insecure algorithms into an internal library module called legacy provider. It is not loaded by default, so apps (or their language runtimes) that use OpenSSL for cryptographic operations cannot use such algorithms when loading certificates, creating message digests ... If you try to load a p12 certificate fo...

From sgcWebSockets 2024.5.0 PKCE, which stands for "Proof of Key Code Exchange" is an extension of the OAuth 2.0 protocol that helps prevent code interception attacks. PKCE is supported on OAuth2 Server and Client Components. What is PKCE PKCE (Proof Key for Code Exchange) is an OAuth 2.0 security enhancement designed to protect against a...

While the openSSL libraries 1.0 and 1.1 are not receiving any more updates, users should consider to use the latest openSSL 3.0 or 3.1 APIs.  Find below the differences between 3.0 and 3.1: OpenSSL 3.0 is a Long Term Support version and will be supported till 7th September 2026.OpenSSL 3.1 will be supported till 14th March 2025....

From sgcWebSockets 2024.2.0 the HTTP/2 server has been improved when receiving HTTP/2 requests. Now, by default, when the server receives a new HTTP/2 request, this is queued and dispatched by one of threads of the Pool of Threads. This avoid the problem when several requests are sent using the same connection and those are processed sequentially. ...

Indy supports RSA and EC Certificates when using the openSSL libraries, but by default, the EC certificates can be created different curves and the openSSL libraries only are configured with some of these curves. So if you're using an EC Certificate that it's not included by the default by the openSSL libraries, the certificate won't work...

Azure IoT allows to send data using several protocols like MQTT or AMQP, but in some cases, the size of the message is too big and requires to upload files to Azure Servers. To provide a solution to this issue IoT hub facilitates file uploads from connected devices by providing them with shared access signature (SAS) URIs on a per-upload basis...

From sgcWebSockets 2023.7.0 the Microsoft Azure OpenAI Service is supported.  Azure OpenAI Service can be used to create chatbots, generate text, translate languages, and write different kinds of creative content. As the platform continues to evolve, developers will be able to use it to build even more powerful and sophisticated applications. ...

In a previous post, we see how to use OpenAI Embeddings to add contextual information to OpenAI chat methods. Now, we'll see how to use the TsgcOpenAIEmbeddings component from sgcWebSockets package to build AI applications using our own data. In the post Delphi Voice ChatBot, we used the component TsgcAIOpenAIChatBot to build a ChatBot handled...

When we ask to OpenAI a question that requires some specific context, example: Who is my father? OpenAI can either hallucinate or answer that he doesn't know. To help OpenAI answer specific questions, you can provide extra contextual information in the prompt itself. My father lives in Barcelona and is 50 year's old. If we ask again to openAI the s...
