What this tool does
- Convert a Cookie header into readable JSON.
- Preserve repeated names as arrays.

Output
{
"sid": "abc123",
"token": "a=b"
}Because no complete fingerprint format can be defined reliably, this tool implements strict generic Cookie JSON conversion only; its format is marked generic-cookie-json.
Frequently asked questions
Is this a complete fingerprint-browser conversion?
No. The proprietary format is not defined, so only generic Cookie JSON is provided.
Are repeated names lost?
No. Repeated values are preserved in encounter order as an array.
Are values decoded?
URI components are decoded by default; decode can be disabled and malformed encoding is rejected.
