From 7111a92546253d6fc857f7cad8b0bff425df0798 Mon Sep 17 00:00:00 2001

Subject: [PATCH 03/11] Use EVP_PKEY for RSA signing operations
With this change all RSA private key operations (excluding import/export) use the EVP_PKEY APIs.
* RSAPaddingProcessor is no longer used in conjunction with the private keys, on Linux.
* The pal_rsa.c copy of HasPrivateKey has been removed.
