Abstract
Embodiments of the present invention address deficiencies of the art in respect to symmetric key generation and provide a method, system and computer program product for symmetric key generation using an asymmetric private key. In one embodiment, a symmetric key generation data processing system can include a symmetric key generator configured with a programmatic interface including an input parameter for a seed, an input parameter for an asymmetric private key, and an output parameter for a symmetric key. The symmetric key generator can include program code enabled to generate the symmetric key by encrypting the seed with the asymmetric private key.
