signing buffers

[Rick H. Wesson]

g10:

I'm not on the g10 list so please respond back to wessorh at ar.com

I am atempting to write a Java Native methods package that implements
gnupg, I have read some of the sources and am looking for a way to 
sign and verify buffers, is there a simple way (like in PGP's libsimple)
to sign a buffer with a given key?

is do_sign in g10/sign.c an appropiate place to start?

thanks,
