Issue with 2.3.5 and "cipher none"

[vcapuano]

Hi All,

I have compiled and installed the new version 2.3.5 on linux.

I have "cipher none" in my configuration. It doesn't work anymore. It gives this error:

Fri Nov 7 19:47:46 2014 OpenVPN 2.3.5 x86_64-unknown-linux-gnu [SSL (OpenSSL)] [LZO] [EPOLL] [MH] [IPv6] built on Nov 7 2014
Fri Nov 7 19:47:46 2014 library versions: OpenSSL 1.0.1e-fips 11 Feb 2013, LZO 2.03

Fri Nov 7 19:47:46 2014 Assertion failed at crypto_openssl.c:523
Fri Nov 7 19:47:46 2014 Exiting due to fatal error

I have copied the file crypto_openssl.c from version 2.3.2 and done a few changes to make it compile on version 2.3.5. And now it works and accepts "cipher none" configuration. My patch is not very clean as it basically removes most of the added changes to this file.

If it can be helpful, I have noticed the same error in the Windows client version 2.3.5.

Thanks,
Vincenzo
