That is the definition for hash functions. The other commenter was, not to put too fine a point on it, wrong. From Schneier's Self-Study Course in Block-Cipher Cryptanalysis:

"Breaking a cipher simply means finding a weakness in the cipher that can be exploited with a complexity less than brute-force."

But please go on about how you know more than Schneier.

You're disregarding the context of those words.

Schneier is illustrating the gap between the academic and practical meanings of "broken".

The term you're looking for is "compromised."
