How to generate random SHA1 hash to use as ID in node.js?

StackOverflow https://stackoverflow.com/questions/9407892

Question

I am using this line to generate a sha1 id for node.js:

crypto.createHash('sha1').digest('hex');

The problem is that it's returning the same id every time.

Is it possible to have it generate a random id each time so I can use it as a database document id?

No correct solution
