Constructor & Destructor Documentation

RSAPrivateKey() [1/2]

QCA::RSAPrivateKey::RSAPrivateKey

(

)

Generate an empty RSA private key.

RSAPrivateKey() [2/2]

QCA::RSAPrivateKey::RSAPrivateKey	(	const BigInteger &	n,
		const BigInteger &	e,
		const BigInteger &	p,
		const BigInteger &	q,
		const BigInteger &	d,
		const QString &	provider = QString() )

Generate an RSA private key from specified parameters.

Parameters

n	the public key value
e	the public key exponent
p	one of the two chosen primes
q	the other of the two chosen primes
d	inverse of the exponent, modulo (p-1)(q-1)
provider	the provider to use, if a particular provider is required

Member Function Documentation

d()

BigInteger QCA::RSAPrivateKey::d

(

)

const

The inverse of the exponent, module (p-1)(q-1)

e()

BigInteger QCA::RSAPrivateKey::e

(

)

const

The public key exponent.

This value is the exponent chosen in the original key generator step

n()

BigInteger QCA::RSAPrivateKey::n

(

)

const

The public key value.

This value is the actual public key value (the product of p and q, the random prime numbers used to generate the RSA key), also known as the public modulus.

p()

BigInteger QCA::RSAPrivateKey::p

(

)

const

One of the two random primes used to generate the private key.

q()

BigInteger QCA::RSAPrivateKey::q

(

)

const

The second of the two random primes used to generate the private key.
