  "description": "This example now demonstrates how to properly attach an artifact signature to a\\nFHIR Library resource using the CRMI signature extension.\\n\\nThe generated SHA256 checksum of the current resource (which excludes `id`,\\n`text`, and `meta`), in minified JSON form is:\\n```\\n892c98e8660c3b84f88cffc4759880ea6f73afa9f58a5ee5dd2f8b7c48250dca\\n```\\n\\nThe signature `data` value after base64 decoding is a JWT:\\n```\\neyJhbGciOiJSUzM4NCJ9.eyJpc3MiOiJodHRwczovL2xvY2FsaG9zdDozMDAwL29pZGMiLCJoYXNoIjoiODkyYzk4ZTg2NjBjM2I4NGY4OGNmZmM0NzU5ODgwZWE2ZjczYWZhOWY1OGE1ZWU1ZGQyZjhiN2M0ODI1MGRjYSJ9.T581_ZkQee7RnJpePnApDIgWtHCO6GUFltHF3riM0wEEAMuVK8X63OrBZpRMCFZWwJ9_RQk3Jo9q4Tyu5WxnZaFxyH0cDCs21gFuCtUanRf4jep2ZfShjVjmm90AGyAzz6EeTodpWyNL48Js__ZSmK8HahkFos5DWZdi93BZalOPvR-pAnzKgxyrrkdmLFZBjKC6drzqhfTyTY0P2yLZV0x6X3btvkdcci8_tqKDl8xz84Gut4iHr0fivP7CbzBoIO6Dlw1gScFWaE9ATRDvkTnSYu3JVptMZo4xgKhrL3ZQktrQZm1CIQ8tnMn5hCdT7W-DysejxxH9t128FYBA1Q\\n```\\n\\nThe decoded JWT payload contains the following fields:\\n- `iss`: The issuer of the signature, which is the CRMI server URL.\\n- `hash`: The SHA256 checksum of the resource in minified JSON form.\\n```\\n{\\n  \\\"iss\\\": \\\"https://localhost:3000/oidc\\\",\\n  \\\"hash\\\": \\\"892c98e8660c3b84f88cffc4759880ea6f73afa9f58a5ee5dd2f8b7c48250dca\\\"\\n}\\n```\\n\\nThe signature is created using the private key of the CRMI server, ensuring the\\nintegrity and authenticity of the resource.
