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

QCA::KeyGenerator::KeyGenerator ( QObject parent = nullptr)

Create a new key generator.

Parameters
parentthe parent object, if applicable

Member Function Documentation

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
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
domainthe discrete logarithm group that this key should be generated from
providerthe 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.
DLGroup QCA::KeyGenerator::createDLGroup ( QCA::DLGroupSet  set,
const QString provider = QString() 
)

Create a new discrete logarithm group.

Parameters
setthe set of discrete logarithm parameters to generate from
providerthe name of the provider to use, if a particular provider is required.
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
domainthe discrete logarithm group that this key should be generated from
providerthe 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.
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
bitsthe length of key that is required
expthe exponent - typically 3, 17 or 65537
providerthe name of the provider to use, if a particular provider is required
Examples:
rsatest.cpp.
DLGroup QCA::KeyGenerator::dlGroup ( ) const

The current discrete logarithm group.

void QCA::KeyGenerator::finished ( )
signal

Emitted when the key generation is complete.

This is only used in non-blocking mode

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
PrivateKey QCA::KeyGenerator::key ( ) const

Return the last generated key.

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

void QCA::KeyGenerator::setBlockingEnabled ( bool  b)

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

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

blockingEnabled()
