Remove all guards for calls to OpenSSL free functions - all of these functions handle NULL, from at least OpenSSL 1.0.1g onwards.

2015-01-15support --without-openssl at configure timeDamien Miller
Disables and removes dependency on OpenSSL. Many features don't work and the set of crypto options is greatly restricted. This will only work on system with native arc4random or /dev/urandom. Considered highly experimental for now.

CA keys are regular SSH keys. This certificate style avoids the attack surface of X.509 certificates and is very easy to deploy. Certified host keys allow automatic acceptance of new host keys when a CA certificate is marked as sh/known_hosts. see VERIFYING HOST KEYS in ssh(1) for details. Certified user keys allow authentication of users when the signing CA key is marked as trusted in authorized_keys. See "AUTHORIZED_KEYS FILE FORMAT" in sshd(8) for details.
