inline-asset-probe

Fetch a URL with curl/wget, extract inline base64 data URIs, and best-effort decode any content to inspect embedded assets.

Practical utility for quickly extracting inline assets from HTML or CSS and inspecting base64-encoded payloads.

What It Does

• Fetches a target URL using curl or wget
• Scans for inline data:*;base64, assets and saves them as files
• Optionally base64-decodes the entire response as a best-effort probe

Usage

PowerShell:

powershell -ExecutionPolicy Bypass -File run.ps1.txt -Url https://example.com

Save raw response and decode any content:

powershell -ExecutionPolicy Bypass -File run.ps1.txt -Url https://example.com -SaveResponse -DecodeResponse

Limit extracted assets and choose output directory:

powershell -ExecutionPolicy Bypass -File run.ps1.txt -Url https://example.com -OutDir probe_out -MaxAssets 20

Output

• probe_out/response.bin when -SaveResponse
• probe_out/assets/asset_*.ext for extracted inline assets
• probe_out/decoded.bin when -DecodeResponse

Notes

• -DecodeResponse performs a best-effort base64 decode of any content by stripping non-base64 characters and padding to a 4-byte boundary.
• Works best for HTML/CSS pages with inline data URIs.
