From 677add38003b37cab06ebc59260c8d28745bb948 Mon Sep 17 00:00:00 2001 From: Richard Levitte Date: Mon, 18 Nov 2019 01:56:22 +0100 Subject: [PATCH] PROV SERIALIZER: add support for writing RSA keys This also adds the missing accessor RSA_get0_pss_params(), so those parameters can be included in the PKCS#8 data structure without needing to know the inside of the RSA structure.
