Gowrishankar Muthukrishnan Sept. 28, 2023, 9:52 a.m. UTC 
  RSA padding information could be a xform entity rather than part of
crypto op, as it seems associated with hashing algorithm used for
the entire crypto session, where this algorithm is used in message
digest itself. Even in virtIO standard spec, this info is associated
in the asymmetric session creation. Hence, moving this info from
crypto op into xform structure.
