Diffie-Hellman provider.
- Note
- This class is part of the provider plugin interface and should not be used directly by applications. You probably want DHPublicKey or DHPrivateKey instead.
◆ DHContext()
QCA::DHContext::DHContext |
( |
Provider * |
p | ) |
|
|
inline |
Standard constructor.
- Parameters
-
p | the provider associated with this context |
◆ createPrivate() [1/2]
virtual void QCA::DHContext::createPrivate |
( |
const DLGroup & |
domain, |
|
|
bool |
block |
|
) |
| |
|
pure virtual |
Generate a Diffie-Hellman private key.
If block is true, then this function blocks until completion. Otherwise, this function returns immediately and finished() is emitted when the operation completes.
If an error occurs during generation, then the operation will complete and isNull() will return true.
- Parameters
-
domain | the domain values to use for generation |
block | whether to use blocking mode |
◆ createPrivate() [2/2]
Create a Diffie-Hellman private key based on its numeric components.
- Parameters
-
domain | the domain values to use for generation |
y | the public Y component |
x | the private X component |
◆ createPublic()
virtual void QCA::DHContext::createPublic |
( |
const DLGroup & |
domain, |
|
|
const BigInteger & |
y |
|
) |
| |
|
pure virtual |
Create a Diffie-Hellman public key based on its numeric components.
- Parameters
-
domain | the domain values to use for generation |
y | the public Y component |
◆ domain()
virtual DLGroup QCA::DHContext::domain |
( |
| ) |
const |
|
pure virtual |
Returns the public domain component of this Diffie-Hellman key.
◆ y()
Returns the public Y component of this Diffie-Hellman key.
◆ x()
Returns the private X component of this Diffie-Hellman key.
