ahhh... i was afraid of that, that's why i asked about it earlier and i 
was led to believe it will be part of Classpath.

i still haven't had the time to study closely the security classes in 
Classpath, but consider the following:

* the GNU Provider can implement the triplet cipher/mode/pad using the 
Assembly classes.

* the gnu.* subpackages that provide the implementation for the GNU 
Provider, if/when Classpath's single jar is broken into multiple jars, 
can then be (jarred as one of Classpath's jars, and) used by others 
wishing to use an API other than the JCA.

how does that sound?
