In general, no. The de/en-cryption algorithm is the same, but different 
information may be included in the header, and the [de]compression process may 
be different.

Originally, it was intended to enable compatibility, via a build-time define:
#define TC_COMPATIBLE
However this has never been finished or tested. Probably no big deal to do so, 
if anyone really wants it.

The original inspiration was tinycrypt v. 0.4, and no attempt has been made to 
conform to any changes in later versions. Though I'd like to think there's 
nothing incompatible, or else prior tinycrypt encryptions would be useless.
