> However there are loads that were comprised.

There are a lot of interactive systems that have attacks on their key exchange or authentication. And there are hashes that have collision attacks.

But compromises that let you figure out a key that's no longer in use have not been common for a while. And even md5 can't be reversed.

I agree with you about being wary, but I think encryption itself can be one of the stronger links in the chain, even going out 30 years.
