Detailed Description

Class for generating asymmetric key pairs.

This class is used for generating asymmetric keys (public/private key pairs).

Examples

rsatest.cpp.

Definition at line 1137 of file qca_publickey.h.

Constructor & Destructor Documentation

KeyGenerator()

QCA::KeyGenerator::KeyGenerator

(

QObject *

parent = nullptr

)

Create a new key generator.

Parameters

parent

the parent object, if applicable

Member Function Documentation

blockingEnabled()

bool QCA::KeyGenerator::blockingEnabled

(

)

const

Test whether the key generator is set to operate in blocking mode, or not.

Returns

true if the key generator is in blocking mode

See also

setBlockingEnabled

createDH()

PrivateKey QCA::KeyGenerator::createDH	(	const DLGroup &	domain,
		const QString &	provider = QString() )

Generate a Diffie-Hellman key.

This method creates both the public key and corresponding private key. You almost certainly want to extract the public key part out - see PKey::toPublicKey for an easy way.

Parameters

domain	the discrete logarithm group that this key should be generated from
provider	the name of the provider to use, if a particular provider is required

Note

For compatibility, you should use one of the IETF_ groupsets as the domain argument.

createDLGroup()

DLGroup QCA::KeyGenerator::createDLGroup	(	QCA::DLGroupSet	set,
		const QString &	provider = QString() )

Create a new discrete logarithm group.

Parameters

set	the set of discrete logarithm parameters to generate from
provider	the name of the provider to use, if a particular provider is required.

createDSA()

PrivateKey QCA::KeyGenerator::createDSA	(	const DLGroup &	domain,
		const QString &	provider = QString() )

Generate a DSA key.

This method creates both the public key and corresponding private key. You almost certainly want to extract the public key part out - see PKey::toPublicKey for an easy way.

Parameters

domain	the discrete logarithm group that this key should be generated from
provider	the name of the provider to use, if a particular provider is required

Note

Not every DLGroup makes sense for DSA. You should use one of DSA_512, DSA_768 and DSA_1024.

createRSA()

PrivateKey QCA::KeyGenerator::createRSA	(	int	bits,
		int	exp = 65537,
		const QString &	provider = QString() )

Generate an RSA key of the specified length.

This method creates both the public key and corresponding private key. You almost certainly want to extract the public key part out - see PKey::toPublicKey for an easy way.

Key length is a tricky judgment - using less than 2048 is probably being too liberal for long term use. Don't use less than 1024 without serious analysis.

Parameters

bits	the length of key that is required
exp	the exponent - typically 3, 17 or 65537
provider	the name of the provider to use, if a particular provider is required

Examples

rsatest.cpp.

dlGroup()

DLGroup QCA::KeyGenerator::dlGroup

(

)

const

The current discrete logarithm group.

finished

void QCA::KeyGenerator::finished ( )

signal

Emitted when the key generation is complete.

This is only used in non-blocking mode

isBusy()

bool QCA::KeyGenerator::isBusy

(

)

const

Test if the key generator is currently busy, or not.

Returns

true if the key generator is busy generating a key already

key()

PrivateKey QCA::KeyGenerator::key

(

)

const

Return the last generated key.

This is really only useful when you are working with non-blocking key generation

setBlockingEnabled()

void QCA::KeyGenerator::setBlockingEnabled

(

bool

b

)

Set whether the key generator is in blocking mode, nor not.

Parameters

b	if true, the key generator will be set to operate in blocking mode, otherwise it will operate in non-blocking mode
