    Function getGrantFileHash

    • Generates a content hash for a grant file. This can be used for integrity verification.

      Parameters

      • grantFile: GrantFile

        The grant file to generate a hash for

      Returns string

      The keccak256 hash of the grant file as a hex string

      Creates a deterministic keccak256 hash of the grant file by first sorting all object keys recursively to ensure consistent hashing regardless of property order. This hash can be used to verify grant file integrity or as a unique identifier.

      When the grant file cannot be serialized

      const grantFile = {
      grantee: '0x742d35Cc6558Fd4D9e9E0E888F0462ef6919Bd36',
      operation: 'read',
      parameters: { version: '1.0', mode: 'full' }
      };

      const hash = getGrantFileHash(grantFile);
      console.log(`Grant file hash: ${hash}`);
      // "0x1234567890abcdef..."

      // Same grant file with different property order produces same hash
      const grantFile2 = {
      operation: 'read',
      parameters: { mode: 'full', version: '1.0' },
      grantee: '0x742d35Cc6558Fd4D9e9E0E888F0462ef6919Bd36'
      };

      const hash2 = getGrantFileHash(grantFile2);
      console.log(hash === hash2); // true
