Trying to find a good javascript function for hmac-sha1

Question

So i have been searching the web for a javascript source for an Hmac-sha1 algorithm. I saw Crypto's but i cant seem to get it to work, mainly because it has no idea what crypto means. (i copied the .js script functions into my script file)
http://code.google.com/p/crypto-js/
I have my base64 encoded function already. that i got from here:

btw this for a twitter application using the new OAuth system.

any help or links to where i can find anything on this would be helpful
If you need me to elaborate let me know. thank you!

Answer 1

I haven't tried it, but 'jssha' seems to have added HMAC support to its SHA-X library recently:
