Release announcements, deep dives and tutorials from the blog. The 20 most recent, newest first.
A TLS 1.3 and TLS 1.2 engine written in Object Pascal, so a Delphi client or server speaks TLS with no DLL beside the executable, and negotiates hybrid post-quantum key exchange while it is at it…
TsgcSSEClient reads a Server-Sent Events stream, reconnects on its own and resumes with Last-Event-ID, so a dropped connection does not lose a message. Coming in sgcWebSockets 2026.10…
A PDF invoice or a photo of a receipt goes in, validated JSON comes out, with a confidence for every field. TsgcAIDocumentExtractor is coming in sgcWebSockets 2026.10…
Describe a page in a sentence, or point it at a screenshot, and the sgcHTML designer builds it out of your own components, through a schema that cannot name anything you did not register…
A signing server does not need your installer, only its digest. The sgcSign Server hash routes sign an MSI or MSIX from a few dozen bytes, and the package never leaves the build agent…
TsgcMSISigner and TsgcAppxSigner sign .msi, .msp, .msix and .appx files from Delphi with a timestamp, and refuse an MSIX whose publisher does not match the certificate…
An MCP tool that answers with a page instead of a paragraph: sgcHTML pages now render inside ChatGPT, Claude and VS Code, and the clicks come back to your Delphi application…
Authenticode signing no longer needs Windows. A short Delphi program built for Linux 64-bit signs an EXE with a timestamp, and Windows accepts the signature like any other…
Czech EET 2.0 reporting starts on 1 January 2027. TsgcEETClient signs and sends each sale, reads the pok and verifies the acknowledgement, with verification mode and an offline queue…
Release 2026.9.0 for sgcWebSockets, sgcWebSockets .NET, sgcSign, sgcIndy and sgcOpenAPI: a native WebRTC media engine, a new cryptography package, trust anchors in verification…
sgcWebRTC is a new WebRTC media engine for Delphi and C++ Builder: SDP signalling, ICE with STUN and TURN, DTLS-SRTP, SCTP data channels and Opus, G.711, VP8 and H.264 media, with no browser and no WebView…
sgcOpenAPI 2026.9.0 rewrites the parser: OpenAPI 3.1 and 3.2, a Warnings list instead of silent failures, working schema composition, correct enums, safe external references and a scriptable command line…
sgcSign 2026.9.0: trust anchors in verification, richer certificate lists, multi-slot PKCS#11 without a PIN, two new PAdES profiles, signed timestamp requests and one shared HTTP transport…
sgcHTML adds CameraScanner, NumPad, CommandPalette and EmptyState, then puts all four to work in five brand new live demos: a Warehouse, a Point of Sale till, Reports & Analytics, a Multi-Tenant SaaS platform and Field Service…
A Huobi and HTX signing defect mixed the local date with the UTC time, so a host running outside UTC had every private request fail for part of the day. It read as an intermittent authentication problem, and it was a two-line fix…
Four Kraken defects fixed in 2026.9: the spot WebSocket client was speaking v1 while connected to a v2 endpoint, Futures REST orders went out as GET with the signed body discarded, and private subscriptions never replayed after a reconnect…
sgcWebSockets 2026.9.0 adds the sgcHTML Design Surface, so pages can be composed visually on a VCL form instead of only in code, using the exact same components and producing the exact same HTML…
Your AI assistant has never read the eSeGeCe source, so it invents properties that do not exist. Agent skills fix that, free and MIT licensed…
sgcCrypto is a new 43-unit cryptography library for Delphi and C++ Builder: AES-GCM, ChaCha20-Poly1305, SHA-3, Argon2, Ed25519, X.509 and post-quantum ML-KEM, ML-DSA and SLH-DSA, included free from sgcWebSockets Standard up…
