Map reduce - need to use sha1 javascript function

Hi,

While writing Map Reduce in Couchbase, I have encountered an issue that while emitting key,value from MAP function has very long key and hence i want to convert the key to unique hash using SHA1 function. I do know that couchbase internally uses sha1 JS libraries but somehow I am not able to import and use it in my code. Any help will be greatly appreciated.

Thanks,
Manish

You can implement your sha1 in javascript and put into the map function body. I have and example here: http://avsej.net/2013/analyzing-binary-data-in-couchbase/
