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. Reimplemented in DL_GroupParameters< T >, DL_PrivateKeyImpl< GP >, DL_PublicKeyImpl< GP >, DL_GroupParameters< Integer >, DL_GroupParameters< typenameEcPrecomputation< EC >::Element >, DL_PrivateKeyImpl< DL_GroupParameters_EC< EC > >, and DL_PublicKeyImpl< DL_GroupParameters_EC< EC > >.

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) Definition at line 278 of file cryptlib.h.
