Detailed Description

RSA provider.

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

QCA::RSAContext::RSAContext ( Provider p)
inline

Standard constructor.

Parameters
pthe provider associated with this context

Member Function Documentation

virtual void QCA::RSAContext::createPrivate ( int  bits,
int  exp,
bool  block 
)
pure virtual

Generate an RSA 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
bitsthe length of the key to generate, in bits
expthe exponent to use for generation
blockwhether to use blocking mode
virtual void QCA::RSAContext::createPrivate ( const BigInteger n,
const BigInteger e,
const BigInteger p,
const BigInteger q,
const BigInteger d 
)
pure virtual

Create an RSA private key based on the five components.

Parameters
nthe N parameter
ethe public exponent
pthe P parameter
qthe Q parameter
dthe D parameter
virtual void QCA::RSAContext::createPublic ( const BigInteger n,
const BigInteger e 
)
pure virtual

Create an RSA public key based on the two public components.

Parameters
nthe N parameter
ethe public exponent
virtual BigInteger QCA::RSAContext::d ( ) const
pure virtual

Returns the private D component of this RSA key.

virtual BigInteger QCA::RSAContext::e ( ) const
pure virtual

Returns the public E component of this RSA key.

virtual BigInteger QCA::RSAContext::n ( ) const
pure virtual

Returns the public N component of this RSA key.

virtual BigInteger QCA::RSAContext::p ( ) const
pure virtual

Returns the private P component of this RSA key.

virtual BigInteger QCA::RSAContext::q ( ) const
pure virtual

Returns the private Q component of this RSA key.
