Detailed Description

DSA provider.

Note
This class is part of the provider plugin interface and should not be used directly by applications. You probably want DSAPublicKey or DSAPrivateKey instead.

Member Function Documentation

virtual void QCA::DSAContext::createPrivate ( const DLGroup domain,
bool  block 
)
pure virtual

Generate a DSA 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
domainthe domain values to use for generation
blockwhether to use blocking mode
virtual void QCA::DSAContext::createPrivate ( const DLGroup domain,
const BigInteger y,
const BigInteger x 
)
pure virtual

Create a DSA private key based on its numeric components.

Parameters
domainthe domain values to use for generation
ythe public Y component
xthe private X component
virtual void QCA::DSAContext::createPublic ( const DLGroup domain,
const BigInteger y 
)
pure virtual

Create a DSA public key based on its numeric components.

Parameters
domainthe domain values to use for generation
ythe public Y component
virtual DLGroup QCA::DSAContext::domain ( ) const
pure virtual

Returns the public domain component of this DSA key.

virtual BigInteger QCA::DSAContext::x ( ) const
pure virtual

Returns the private X component of this DSA key.

virtual BigInteger QCA::DSAContext::y ( ) const
pure virtual

Returns the public Y component of this DSA key.
