inlinevirtualinherited |
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.

inlinevirtualinherited |
Get a named value.
name | the name of the object or value to retrieve |
valueType | reference to a variable that receives the value |
pValue | void pointer to a variable that receives the value |
GetVoidValue() retrives the value of name if it exists.
Implements NameValuePairs.

Assign values to this object.
This function can be used to create a public key from a private key.
Implements CryptoMaterial.
|
inlinevirtualinherited |
Generate a random key or crypto parameters.
rng | a RandomNumberGenerator to produce keying material |
params | additional initialization parameters |
KeyingErr | if a key can't be generated or algorithm parameters are invalid |
If a derived class does not override GenerateRandom, then the base class throws NotImplemented.

Determines whether the object supports precomputation.
Reimplemented from CryptoMaterial.
|
inlinevirtualinherited |
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.
Reimplemented from CryptoMaterial.

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