possible to compute plain old HMAC-SHA1 of buffer with krb5 api?

[Chris Hecker]

Is it possible to compute a regular old hmac_sha1 with the krb5 api?  In 
other words, the normal api is digest = hmac_sha1(data,pass).  I notice 
there are a bunch of hmac functions and krb5int_hmac is even exported, 
but it's not clear how to call it to be compatible with a regular hmac_sha1.

No big deal if it's not possible, since there's a lot of code out there, 
but since I'm already linking krb5...

Thanks,
Chris
