+# Deprecated Package
+
+This package is no longer supported and has been deprecated. To avoid malicious use, npm is hanging on to the package name.
+
+It's now a built-in Node module. If you've depended on crypto, you should switch to the one that's built-in.
+
+Please contact support@npmjs.com if you have questions about this package.
