Free API lets course providers issue tamper-proof certificates with one HTTP call

·7 views

Novadyne has released Attestify, a free API that allows course providers and training programs to issue cryptographically signed completion certificates without requiring an account or API key. Each certificate is backed by a server-side record and an Ed25519 digital signature, making any alteration instantly detectable during verification. Recipients receive a permanent public verification URL that anyone — including employers — can open without creating an account or installing an app. The API integrates with automation tools like n8n and supports batch issuance for multiple recipients in a single request. Attestify positions itself as a lightweight alternative to full credentialing platforms, focusing solely on free, programmatic certificate issuance and public verification.

ADT Confirms Data Breach After ShinyHunters Claims 10 Million Records Stolen

Home security giant ADT confirmed a data breach on April 24, 2026, after hacker group ShinyHunters posted what they claim are roughly 10 million customer records on a leak forum the previous day. The stolen data reportedly includes full names, email addresses, home addresses, phone numbers, and service plan details, though ADT stated that payment card numbers, Social Security numbers, and alarm credentials were not compromised. Multiple cybersecurity outlets independently verified records from the leaked sample, and several affected customers also confirmed their own information appeared in the data. ADT said its security team has contained the unauthorized access and is now notifying impacted customers while offering complimentary credit monitoring. The company has not disclosed how attackers gained entry, and no details have been shared about whether the breach involved an internal system, a customer-facing application, or a third-party service provider.

Developer Ditches Paid AI Coding Tools for Free Local Alternative MonkeyCode

A software developer with five years of experience has switched from paid AI coding assistants like Cursor, GitHub Copilot, and Windsurf to MonkeyCode, a free open-source platform that runs entirely on a local machine. The primary reasons cited were privacy concerns, since most commercial tools send code context to remote servers, and cumulative subscription costs that can reach hundreds of dollars per year per developer. MonkeyCode supports multiple AI models, including local options via Ollama, and integrates with popular editors such as VS Code and JetBrains IDEs. The developer reported using the tool daily for three weeks across tasks including code completion, refactoring, and code review, with no usage limits or account requirements. The project is self-hosted via Docker and has accumulated over 3,700 stars on GitHub, though the developer noted its UI and English documentation are less polished than commercial rivals.

How Pinned UI Strings in Smoke Tests Masked a Real Production Bug for a Week

A software team at nlqdb discovered that their acceptance test walkers, which assert exact UI strings, all reported 0/9 failures for an entire week after a homepage redesign, a copy edit, and a catalog update simultaneously broke the tests. Two of the three failures turned out to be test drift — outdated string expectations — while one was an actual production issue, but the identical failure score made them indistinguishable without manual investigation. The team concluded that pinned literals are a valid regression tool, but only when failures are triaged quickly and test output clearly names the failing element and its expected value. A pre-existing rule requiring walkers to re-run on any PR touching a walked surface was skipped because it was a convention rather than an enforced gate. The key lessons are that unexplained test failures accumulate noise that can obscure real outages, and that unenforced testing conventions offer no real protection.

Why Reading a JWT Is Not the Same as Verifying It

JSON Web Tokens (JWTs) consist of three dot-separated segments — header, payload, and signature — where the first two are merely Base64url-encoded JSON readable by anyone without a key. Because the payload is not encrypted, developers should never store sensitive data such as passwords or API keys inside a token, as it is effectively public. Security in JWTs comes entirely from the third segment, a keyed HMAC or digital signature computed using a server-held secret, which makes tokens tamper-evident but not confidential. A common and dangerous mistake is decoding the payload to read claims and acting on them without first verifying the signature, which leaves applications open to forgery attacks. Base64url encoding is used instead of standard Base64 to ensure tokens remain intact when placed in URLs, as standard Base64 characters like '+', '/', and '=' carry structural meaning in web addresses.
