Constructors
RSAKeyImpl
RSAKeyImpl(
const EVPPKey & key
);
Constructs RSAKeyImpl by extracting the RSA key.
RSAKeyImpl
RSAKeyImpl(
const X509Certificate & cert
);
Extracts the RSA public key from the given certificate.
RSAKeyImpl
RSAKeyImpl(
const PKCS12Container & cert
);
Extracts the RSA private key from the given certificate.
RSAKeyImpl
RSAKeyImpl(
int keyLength,
unsigned long exponent
);
Creates the RSAKey. Creates a new public/private keypair using the given parameters. Can be used to sign data and verify signatures.
RSAKeyImpl
RSAKeyImpl(
const std::string & publicKeyFile,
const std::string & privateKeyFile,
const std::string & privateKeyPassphrase
);
Creates the RSAKey, by reading public and private key from the given files and using the given passphrase for the private key. Can only by used for signing if a private key is available.
RSAKeyImpl
RSAKeyImpl(
std::istream * pPublicKeyStream,
std::istream * pPrivateKeyStream,
const std::string & privateKeyPassphrase
);
Creates the RSAKey. Can only by used for signing if pPrivKey is not null. If a private key file is specified, you don't need to specify a public key file. OpenSSL will auto-create it from the private key.
Destructor
~RSAKeyImpl 
~RSAKeyImpl();
Destroys the RSAKeyImpl.
Member Functions
decryptionExponent
ByteVec decryptionExponent() const;
Returns the RSA decryption exponent.
encryptionExponent
ByteVec encryptionExponent() const;
Returns the RSA encryption exponent.
getRSA 
RSA * getRSA();
Returns the OpenSSL RSA object.
getRSA
const RSA * getRSA() const;
Returns the OpenSSL RSA object.
modulus
ByteVec modulus() const;
Returns the RSA modulus.
save
void save(
const std::string & publicKeyFile,
const std::string & privateKeyFile = "",
const std::string & privateKeyPassphrase = ""
) const;
Exports the public and private keys to the given files.
If an empty filename is specified, the corresponding key is not exported.
See also: Poco::Crypto::KeyPairImpl::save()
save
void save(
std::ostream * pPublicKeyStream,
std::ostream * pPrivateKeyStream = 0,
const std::string & privateKeyPassphrase = ""
) const;
Exports the public and private key to the given streams.
If a null pointer is passed for a stream, the corresponding key is not exported.

size
int size() const;
Returns the RSA modulus size.
