And your credentials are different too:

var credentials = "admin:amin";
credentials = "admin:admin"

Is this also a cut & paste error?

Please, post EXACTlY the code you are actually running.  Otherwise, it 
really is impossible for anybody to figure out what you're doing wrong.  
This is double ultra especially true with crypto, since small 
differences in the inputs result (by design) in huge differences in the 
output.
