comment Determine safety of exercise hash functions
Since there are no restrictions on what $h_{666}$ is, and the question says "may be less safe", you're allowed to assume the worst about $h_{666}$. For A) you could assume that it returns a constant value. For C) what if $h_{666}=h_{md5}(m) \oplus h_{sha1}(m) \oplus h_B(m)$ plus some constant padding?

@fgrieu I think the zero-padding referred to the individual hashes, expanding them all to 666 bits so you can xor them, not the the messages.

Can you elaborate on the context where you heard this? The closest thing I know is polymorphic malware.
