Support asymetric RSA in Crypto API


 * Summary: Support asymetric RSA in Crypto API
 * Proposer: Tim Bird, Sony Mobile
 * Status: Not selected in 2013 to be sponsored by the CE Workgroup

Description
The current AF_ALG interface to user space only supports hash and symmetric algorithms. Some user applications may want to utilize HW crypto engine's asymetric algorithm, like RSA. The purpose of this project would be to add full RSA support in the kernel, extending the crypto API if needed.

Reasons for CEWG not selecting this project
This project seemed useful, and many companies were interested. However, the only bid received was from a company that looked likely to already receive some projects this round (and they might not have the bandwidth to work on this and others.) This was rated lower priority than other projects bid upon by the same contractor.
