That depends on what you want to do next. m.digest() returns the digest 
in binary form, ready to be used for further manipulation, such as 
having it signed. m.hexdigest() returns it in a form suitable for 
inclusion in a text transmission, such as email.

PKCS #1 has not been integrated into trunk yet. There is a patch 
available, though, here: https://bugs.launchpad.net/pycrypto/+bug/502291
