+
+URL and cookie safe UIDs
+
+Create cryptographically secure UIDs safe for both cookie and URL usage.
+This is in contrast to modules such as [rand-token](https://www.npmjs.com/package/rand-token)
+and [uid2](https://www.npmjs.com/package/uid2) whose UIDs are actually skewed
+due to the use of `%` and unnecessarily truncate the UID.
+Use this if you could still use UIDs with `-` and `_` in them.
+
+## Installation
+
+```sh
+$ npm install uid-safe
+```
+
+## API
+
+```js
+var uid = require('uid-safe')
+```
+
+### uid(byteLength, callback)
+
+Asynchronously create a UID with a specific byte length. Because `base64`
+encoding is used underneath, this is not the string length. For example,
+to create a UID of length 24, you want a byte length of 18.
+
+```js
+uid(18, function (err, string) {
+  if (err) throw err
+  // do something with the string
+})
+```
+
+### uid(byteLength)
+
+Asynchronously create a UID with a specific byte length and return a
+`Promise`.
+
+**Note**: To use promises in Node.js _prior to 0.12_, promises must be
+"polyfilled" using `global.Promise = require('bluebird')`.
+
+```js
+uid(18).then(function (string) {
+  // do something with the string
+})
+```
+
+### uid.sync(byteLength)
+
+A synchronous version of above.
+
+```js
+var string = uid.sync(18)
+```
