Detailed Description

Encapsulates parameters related to the generation of an asymmetric cryptographic key pair based on an elliptic curve

This class encapsulates a variety of parameters which will affect how the crypto plugin generates a key pair. Usually, an instance of this class will be used when performing a GenerateStoredKeyRequest.

An example of parameters to generate an elliptic curve key pair for use in ECDSA and ECDH operations follows:

 Sailfish::Crypto::EcKeyPairGenerationParameters eckpgParams;
 eckpgParams.setEllipticCurve(Sailfish::Crypto::CryptoManager::Curve25519);

The security size of the generated key will depend on the size of the field over which the curve is defined. For example, Curve25519 is a 255-bit elliptic curve requiring 252-bit private keys (usually encoded as 256-bit values with four fixed bits), providing security approximately equivalent to using a 128-bit symmetric cipher key, or 3072 bit RSA key.

Support for different curves is entirely plugin-specific; please see the documentation for the crypto plugin you intend to use for more information about the different curves which are supported, and what (if any) custom parameters may be supported.
