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
|
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
- See also
- blockingEnabled()
