template<class GP>

DL_GroupParameters<Element>& DL_PublicKeyImpl< GP >::AccessAbstractGroupParameters ( )

inlinevirtual

Retrieves abstract group parameters.

Returns: a non-const reference to the group parameters

Implements DL_Key< GP::Element >.

Definition at line 1241 of file pubkey.h.

template<class GP>

DL_FixedBasePrecomputation<Element>& DL_PublicKeyImpl< GP >::AccessPublicPrecomputation ( )

inlinevirtual

Implements DL_PublicKey< GP::Element >.

Definition at line 1245 of file pubkey.h.

template<class GP>

void DL_PublicKeyImpl< GP >::AssignFrom ( const NameValuePairs & source )

inlinevirtual

Assign values to this object.

This function can be used to create a public key from a private key.

Implements CryptoMaterial.

Definition at line 1214 of file pubkey.h.

Here is the caller graph for this function:

template<class GP>

const DL_GroupParameters<Element>& DL_PublicKeyImpl< GP >::GetAbstractGroupParameters ( ) const

inlinevirtual

Retrieves abstract group parameters.

Returns: a const reference to the group parameters

Implements DL_Key< GP::Element >.

Definition at line 1240 of file pubkey.h.

template<class GP>

const DL_FixedBasePrecomputation<Element>& DL_PublicKeyImpl< GP >::GetPublicPrecomputation ( ) const

inlinevirtual

Implements DL_PublicKey< GP::Element >.

Definition at line 1244 of file pubkey.h.

template<class GP>

bool DL_PublicKeyImpl< GP >::GetVoidValue	(	const char *	name,
		const std::type_info &	valueType,
		void *	pValue
	)		const

inlinevirtual

Get a named value.

Parameters

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

Returns: true if the value was retrieved, false otherwise

GetVoidValue() retrieves the value of name if it exists.

Note: GetVoidValue() is an internal function and should be implemented by derived classes. Users should use one of the other functions instead.

See also: GetValue(), GetValueWithDefault(), GetIntValue(), GetIntValueWithDefault(), GetRequiredParameter() and GetRequiredIntParameter()

Implements NameValuePairs.

Definition at line 1209 of file pubkey.h.

template<class GP>

void DL_PublicKeyImpl< GP >::LoadPrecomputation ( BufferedTransformation & storedPrecomputation )

inlinevirtual

Retrieve previously saved precomputation.

Parameters

storedPrecomputation BufferedTransformation with the saved precomputation

Exceptions

NotImplemented

See also: SupportsPrecomputation(), Precompute()

Reimplemented from CryptoMaterial.

Definition at line 1227 of file pubkey.h.

template<class GP>

bool DL_PublicKeyImpl< GP >::operator== ( const DL_PublicKeyImpl< GP > & rhs ) const

inline

Definition at line 1248 of file pubkey.h.

template<class GP>

void DL_PublicKeyImpl< GP >::Precompute ( unsigned int precomputationStorage = 16 )

inlinevirtual

Perform precomputation.

Parameters

precomputationStorage the suggested number of objects for the precompute table

Exceptions

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.

See also: SupportsPrecomputation(), LoadPrecomputation(), SavePrecomputation()

Reimplemented from CryptoMaterial.

Definition at line 1221 of file pubkey.h.

template<class GP>

void DL_PublicKeyImpl< GP >::SavePrecomputation ( BufferedTransformation & storedPrecomputation ) const

inlinevirtual

Save precomputation for later use.

Parameters

storedPrecomputation BufferedTransformation to write the precomputation

Exceptions

NotImplemented

See also: SupportsPrecomputation(), Precompute()

Reimplemented from CryptoMaterial.

Definition at line 1233 of file pubkey.h.

template<class GP>

bool DL_PublicKeyImpl< GP >::SupportsPrecomputation ( ) const

inlinevirtual

Determines whether the object supports precomputation.

Returns: true if the object supports precomputation, false otherwise

See also: Precompute()

Reimplemented from CryptoMaterial.

Definition at line 1219 of file pubkey.h.

template<class GP>

bool DL_PublicKeyImpl< GP >::Validate	(	RandomNumberGenerator &	rng,
		unsigned int	level
	)		const

inlinevirtual

Check this object for errors.

Parameters

rng	a RandomNumberGenerator for objects which use randomized testing
level	the level of thoroughness

Returns: true if the tests succeed, false otherwise

There are four levels of thoroughness:

0 - using this object won't cause a crash or exception
1 - this object will probably function, and encrypt, sign, other operations correctly
2 - ensure this object will function correctly, and perform reasonable security checks
3 - perform reasonable security checks, and do checks that may take a long time

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.
