SHA1 error in tinyecc

Hi,

When I try to use the SHA1 function in tinyecc-2.0 IN TINYOS-2.1.2, i get
the following error:

IN the configuration file I give,

implementation {
components DisseminationC as App;

App.SHA1 -> SHA1M;

Here SHA1.nc is the interface file and SHA1M.nc is the module file.

i get an error:

In component `DisseminationAppC':
DisseminationAppC.nc:19: expected component `SHA1', but got a component
DisseminationAppC.nc:31: cannot find `SHA1M'

HOW TO SOLVE THIS? PLEASE HELP ME....

Regards,
