check this object for errors
level | denotes the level of thoroughness: 0 - using this object won't cause a crash or exception (rng is ignored) 1 - this object will probably function (encrypt, sign, etc.) correctly (but may not check for weak keys and such) 2 - make sure this object will function correctly, and do reasonable security checks 3 - do checks that may take a long time |

do precomputation
The exact semantics of Precompute() is varies, but typically it means calculate a table of n objects that can be used later to speed up computation.

get a named value with type int
used to ensure we don't accidentally try to get an unsigned int or some other type when we mean int (which is the most common case)
