Detailed Description

RSA Public Key.

Definition at line 1275 of file qca_publickey.h.

Constructor & Destructor Documentation

QCA::RSAPublicKey::RSAPublicKey ( )

Generate an empty RSA public key.

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

Generate an RSA public key from specified parameters.

Parameters
nthe public key value
ethe public key exponent
providerthe provider to use, if a particular provider is required
QCA::RSAPublicKey::RSAPublicKey ( const RSAPrivateKey k)

Extract the public key components from an RSA private key.

Parameters
kthe private key to use as the basis for the public key

Member Function Documentation

BigInteger QCA::RSAPublicKey::e ( ) const

The public key exponent.

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

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.
