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.

Constructor & Destructor Documentation

RSAContext()

QCA::RSAContext::RSAContext ( Provider *  p )

inline

Member Function Documentation

createPrivate() [1/2]

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

n	the N parameter
e	the public exponent
p	the P parameter
q	the Q parameter
d	the D parameter

createPrivate() [2/2]

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

bits	the length of the key to generate, in bits
exp	the exponent to use for generation
block	whether to use blocking mode

createPublic()

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

n	the N parameter
e	the public exponent

d()

virtual BigInteger QCA::RSAContext::d ( ) const

pure virtual

Returns the private D component of this RSA key.

e()

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

pure virtual

Returns the public E component of this RSA key.

n()

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

pure virtual

Returns the public N component of this RSA key.

p()

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

pure virtual

Returns the private P component of this RSA key.

q()

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

pure virtual

Returns the private Q component of this RSA key.
