bool DL_PublicKeyImpl< DL_GroupParameters_EC< EC > >::Validate | ( | RandomNumberGenerator & | rng, | |
unsigned int | level | |||
) | const [inline, virtual, inherited] |
Check this object for errors.
rng | a RandomNumberGenerator for objects which use randomized testing | |
level | the level of thoroughness |
There are four levels of thoroughness:
Level 0 does not require a RandomNumberGenerator. A NullRNG() can be used for level 0.
Level 1 may not check for weak keys and such.
Levels 2 and 3 are recommended.
Implements CryptoMaterial.
bool DL_PublicKeyImpl< DL_GroupParameters_EC< EC > >::SupportsPrecomputation | ( | ) | const [inline, virtual, inherited] |
Determines whether the object supports precomputation.
Reimplemented from CryptoMaterial.
void DL_PublicKeyImpl< DL_GroupParameters_EC< EC > >::Precompute | ( | unsigned int | precomputationStorage = 16 |
) | [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.

name | the name of the value | |

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