+// Custom binding for the enterprise.platformKeys API.
+
+// The platformKeys API consists of two major parts:
+//   - the certificate management.
+//   - the key generation and crypto operations and
+// The former is implemented without custom binding as static functions.
+// The latter is exposed by implementing WebCrypto's SubtleCrypto interface.
+// The internal API provides the key and crypto operations through static
+// functions expecting token IDs and this custom binding adds the SubtleCrypto
+// wrapper.
+// The Token object holds the token id and the SubtleCrypto member.
+
+var binding = require('binding').Binding.create('enterprise.platformKeys');
+var Token = require('enterprise.platformKeys.Token').Token;
+var internalAPI = require('enterprise.platformKeys.internalAPI');
+
+binding.registerCustomHook(function(api) {

+
+  var ret = apiFunctions.setHandleRequest('getTokens', function(callback) {
+    internalAPI.getTokens(function(tokenIds) {
+      callback($Array.map(tokenIds,
+                          function(tokenId) { return new Token(tokenId); }));
