OpenSSL包含一个命令行工具用来完成OpenSSL库中的所有功能，更好的是，它可能已经安装到你的系统中了。
OpenSSL是一个强大的安全套接字层密码库，Apache使用它加密HTTPS，OpenSSH使用它加密SSH，但是，你不应该只将其作为一个库来使用，它还是一个多用途的、跨平台的密码工具。
OpenSSL加密库产品线更新，发布1.0.1f.2014-01-06.之前是1.0.1e.2013-02-11遗留产品线1.0.0k,0.9.8y .
完全改进： Changes between 1.0.1e and 1.0.1f [6 Jan 2014]
*) Fix for TLS record tampering bug. A carefully crafted invalid
handshake could crash OpenSSL with a NULL pointer exception.
Thanks to Anton Johansson for reporting this issues.
(CVE-2013-4353)
*) Keep original DTLS digest and encryption contexts in retransmission
structures so we can use the previous session parameters if they need
to be resent. (CVE-2013-6450)
[Steve Henson]
*) Add option SSL_OP_SAFARI_ECDHE_ECDSA_BUG (part of SSL_OP_ALL) which
avoids preferring ECDHE-ECDSA ciphers when the client appears to be
Safari on OS X. Safari on OS X 10.8..10.8.3 advertises support for
several ECDHE-ECDSA ciphers, but fails to negotiate them. The bug
is fixed in OS X 10.8.4, but Apple have ruled out both hot fixing
10.8..10.8.3 and forcing users to upgrade to 10.8.4 or newer.
