I think this is crying out for another patch - an integration to get
rid of lib/rsa/rsa-checksum.c. You should be able to look up the hash
algorithm name using the hash.h file and get the pad length, etc. from
that. Then you can call this progressive hashing API instead of adding
new code in lib/rsa/rsa-checksum.c.

There may be a catch, but I can't see one at present.

Regards,
Simon
