Member Function Documentation

virtual void GeneratableCryptoMaterial::GenerateRandom	(	RandomNumberGenerator &	rng,
		const NameValuePairs &	params = `g_nullNameValuePairs`
	)

inlinevirtual

Generate a random key or crypto parameters.

Parameters

rng	a RandomNumberGenerator to produce keying material
params	additional initialization parameters

Exceptions

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.

Reimplemented in DL_PrivateKeyImpl< GP >, DL_PrivateKeyImpl< DL_GroupParameters_EC< EC > >, DL_GroupParameters_DSA, InvertibleRSAFunction, InvertibleLUCFunction, InvertibleRWFunction, InvertibleESIGNFunction, InvertibleRabinFunction, DL_GroupParameters_EC< EC >, and DL_GroupParameters_IntegerBased.

Here is the caller graph for this function:

void GeneratableCryptoMaterial::GenerateRandomWithKeySize	(	RandomNumberGenerator &	rng,
		unsigned int	keySize
	)

Generate a random key or crypto parameters.

Parameters

rng	a RandomNumberGenerator to produce keying material
keySize	the size of the key, in bits

Exceptions

KeyingErr if a key can't be generated or algorithm parameters are invalid

GenerateRandomWithKeySize calls GenerateRandom with a NameValuePairs object with only "KeySize"
