[microsoft/vscode] Extension Signature Verification Failed: BLACKBOXAI Agent - Coding Copilot

### ROOT CAUSE The extension "BLACKBOXAI Agent - Coding Copilot" is unsigned or its signature is invalid/expired, preventing VS Code from verifying its authenticity. This typically occurs when extensions are not properly signed by a trusted publisher, or the signature is outdated. ### CODE FIX Sign the extension using a certificate from a trusted Certificate Authority (CA) or VS Code's built-in signing process. Here's the minimal fix for the publisher: ```bash # Install vsce globally npm install -g vsce # Navigate to the extension's root directory cd path/to/extension # Sign the extension with your certificate vsce sign --cert path/to/certificate.pem --key path/to/privatekey.key ``` **Notes:** - Use a certificate from a trusted CA (e.g., Microsoft or OpenSSL) for production. - For development/testing, VS Code allows unsigned extensions in `File > Preferences > Workbench > Extensions > Disable Extensions Security Check`. Avoid this for production.
