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

DHContext()

QCA::DHContext::DHContext ( Provider *  p )

inline

Standard constructor.

Parameters

p	the provider associated with this context

Definition at line 838 of file qcaprovider.h.

Member Function Documentation

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]

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

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.

x()

virtual BigInteger QCA::DHContext::x ( ) const

pure virtual

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

y()

virtual BigInteger QCA::DHContext::y ( ) const

pure virtual

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