How secure is SSL (Secure Socket Layer)? As in, how much will it take to crack a password sent through SSL?

推荐答案

假设一切都正确安装，关于128位密钥，比宇宙的时代长得多。

Assuming everything is setup/secured properly and we're talking about 128-bit keys, significantly longer than the age of the universe.

我会注意到以前的SSL 依赖于MD5中的孔，这导致了一些验证方法的改变。

I would note that previous cracks in SSL relied on "hole" in MD5, which caused some the method of validation to change..

我也会注意到，这不会使您免于在甚至有人劫持目标公司的私人证书（请注意，私钥应该通过强力密码进行保护，尽管如此，为了减轻这种风险，那么如果这样的事件发生）。 阅读关于SSL如何工作的高级概述。

I would also note, this doesn't free you from man-in-the-middle attacks, or even someone hijacking the private cert of the target company (note that private keys should be protected via a strong password though to mitigate such a risk and then the key revoked if such an event occurs).
