Constructor & Destructor Documentation

RSAPublicKey() [1/3]

QCA::RSAPublicKey::RSAPublicKey

(

)

Generate an empty RSA public key.

RSAPublicKey() [2/3]

QCA::RSAPublicKey::RSAPublicKey	(	const BigInteger &	n,
		const BigInteger &	e,
		const QString &	provider = QString() )

Generate an RSA public key from specified parameters.

Parameters

n	the public key value
e	the public key exponent
provider	the provider to use, if a particular provider is required

RSAPublicKey() [3/3]

QCA::RSAPublicKey::RSAPublicKey

(

const RSAPrivateKey &

k

)

Extract the public key components from an RSA private key.

Parameters

k	the private key to use as the basis for the public key

Member Function Documentation

e()

BigInteger QCA::RSAPublicKey::e

(

)

const

The public key exponent.

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

n()

BigInteger QCA::RSAPublicKey::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.
