Return the raw key with no other processing so that the caller can copy it or MPI parse it, etc. The scope is to have only one ANS.1 parser for all RSA implementations. Update the RSA software implementation so that it does the MPI conversion on top. Signed-off-by: Tudor Ambarus <tudor-dan.ambarus@nxp.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
