This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. getSignedCookie verifies and retrieves the raw string value of a valid HMAC-SHA256 signed cookie by name
  2. getSignedCookie returns false when the cookie signature is invalid or tampered with
  3. getSignedCookie returns undefined when the requested cookie is not present or is an unsigned plain cookie
  4. getSignedCookie supports prefix options to extract and verify __Secure- prefixed cookies
  5. getSignedCookie called without a cookie name parameter returns an object containing all valid signed cookies
