Why Rot?

Aside from the infamous ROT13 Caeser cipher, cryptographic keys have a tendency to "rot" rather quickly. Frequent use of keys inevitably leads to leakage and/or compromise, and the underlying encryption algorithms may not be secure in the future. Cryptographic material doesn't age well in general.
