Subject: [PATCH] Add support for PKCS#8 encoded private keys
The code supports PKCS#1 encoded RSA private keys that begin with the
BEGIN RSA PRIVATE KEY header in PEM files. This patch adds support for
RSA private keys encoded in PEM files that begin with the header
BEGIN PRIVATE KEY which are in PKCS#8 format.
