From 1fad008e1adba5cb596da6f9ec6a244d49a585cf Mon Sep 17 00:00:00 2001

Subject: [PATCH] Encrypt: set default RSA key size to 1024 everywhere, using
the RSA_KEY_SIZE macro
This commit also fixes the problem described in #31, which was caused by the test key generated in RsaCheck() being too small for newer OpenSSL versions.
