Member Function Documentation

DhKeyPairGenerationParameters::DhKeyPairGenerationParameters()

Constructs a new DhKeyPairGenerationParameters instance

DhKeyPairGenerationParameters::DhKeyPairGenerationParameters(const KeyPairGenerationParameters &other)

Constructs a copy of the other parameters

DhKeyPairGenerationParameters::~DhKeyPairGenerationParameters()

Destroys the parameters instance

QByteArray DhKeyPairGenerationParameters::base() const

Returns the base generator to be used when generating the key pair

The base is also known as the generator G.

Note: Getter function for property base.

See also setBase().

bool DhKeyPairGenerationParameters::generateFamilyParameters() const

Returns true if the key should be generated using randomly-generated key family parameters

The individual parameters (modulus (prime p), private exponent (prime q), and base (generator g)) define the key family. In order for the algorithm to work, both parties need to use the same parameters in order for their (randomly generated public and private) keys to belong to the same family (and thus work).

If this value is true, the client wants the plugin to generate a key pair using randomly generated key family parameters; otherwise, the client wants the plugin to generate a key pair using the standard key family values specified in FIPS 186-3.

This value is only meaningful if the client has provided a modulusLength() and privateExponentLength(), and is ignored if the client has instead provided a modulus() and base().

Note: Getter function for property generateFamilyParameters.

See also setGenerateFamilyParameters().

[virtual] bool DhKeyPairGenerationParameters::isValid() const

QByteArray DhKeyPairGenerationParameters::modulus() const

Returns the modulus to be used when generating the key pair

The modulus is also known as the large prime P.

Note: Getter function for property modulus.

See also setModulus().

int DhKeyPairGenerationParameters::modulusLength() const

Returns the modulus length of the DH key pair to be generated

This defines the security size of the output key.

Note that this parameter is only meaningful if the client has not provided explicit values for the modulus() and base().

Note: Getter function for property modulusLength.

See also setModulusLength().

int DhKeyPairGenerationParameters::privateExponentLength() const

Returns the private exponent length of the DH key pair to be generated

This is the length (in bits) of the private exponent which will be generated by the base (generator).

Note that this parameter is only meaningful if the client has not provided explicit values for the modulus() and base().

Note: Getter function for property privateExponentLength.

See also setPrivateExponentLength().

void DhKeyPairGenerationParameters::setBase(const QByteArray &g)

Sets the base generator to be used when generating the key pair g

Note: Setter function for property base.

See also base().

void DhKeyPairGenerationParameters::setGenerateFamilyParameters(bool generate)

Sets whether the key should be generated using randomly-generated key family parameters to generate

Note: Setter function for property generateFamilyParameters.

See also generateFamilyParameters().

void DhKeyPairGenerationParameters::setModulus(const QByteArray &p)

Sets the modulus to be used when generating the key pair to p

Note: Setter function for property modulus.

See also modulus().

void DhKeyPairGenerationParameters::setModulusLength(int length)

Sets the modulus length of the DH key pair to be generated to length

Note: Setter function for property modulusLength.

See also modulusLength().

void DhKeyPairGenerationParameters::setPrivateExponentLength(int length)

Sets the private exponent length of the DH key pair to be generated to length

Note: Setter function for property privateExponentLength.

See also privateExponentLength().

DhKeyPairGenerationParameters &DhKeyPairGenerationParameters::operator=(const DhKeyPairGenerationParameters &other)

Assigns the other parameters to this instance
