Level 1 may not check for weak keys and such.
Levels 2 and 3 are recommended.

virtual bool CryptoMaterial::SupportsPrecomputation | ( | ) | const [inline, virtual, inherited] |
Determines whether the object supports precomputation.
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 > >.

virtual void CryptoMaterial::Precompute | ( | unsigned int | precomputationStorage | ) | [inline, virtual, inherited] |
Perform precomputation.
precomputationStorage | the suggested number of objects for the precompute table |
NotImplemented |
The exact semantics of Precompute() varies, but it typically means calculate a table of n objects that can be used later to speed up computation.
If a derived class does not override Precompute, then the base class throws NotImplemented.

Ensures an expected name and type is present.
name | the name of the value | |
stored | the type that was stored for the name | |

ValueTypeMismatch |
ThrowIfTypeMismatch() effectively performs a type safety check. stored and retrieving are C++ mangled names for the type.
