You might be interested in this code:

This checks the signature of an executable in ELF format.  The
signature is therefore embedded within the ELF file and all the tools
to create it should be there too.

If you don't want the ELF support, it is pretty easy to use only the
core verification.  It does only work with DSS signatures.
