Detailed Description

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.

Constructor & Destructor Documentation

QCA::DHContext::DHContext ( Provider p  )  [inline]

Standard constructor.

Parameters:
p the provider associated with this context


Member Function Documentation

virtual void QCA::DHContext::createPrivate ( const DLGroup domain,
const BigInteger y,
const BigInteger x 
) [pure virtual]

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

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

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

virtual DLGroup QCA::DHContext::domain (  )  const [pure virtual]

Returns the public domain component of this Diffie-Hellman key.

virtual BigInteger QCA::DHContext::x (  )  const [pure virtual]

Returns the private X component of this Diffie-Hellman key.

virtual BigInteger QCA::DHContext::y (  )  const [pure virtual]

Returns the public Y component of this Diffie-Hellman key.
