Ode to an MD5 Checksum

Before I made my hash
I forgot to add the salt.
Now you've become so predictable
and it's really all my fault.

Bathed in white noise
from some foreign sector,
Is this the dubious voice
of an alien initialization vector?

Pay heed to the conductor
don't sully the notation.
Every bit dances through
their left-bit rotation.

One step forward
one step back.
I should have seen this coming -
a surprise birthday attack!

A torpor of smoke and confusion
amid flashing lights and double-vision,
the message is beset with peril
after a harrowing hash collision

The message must get through
if the cipher is somehow able -
to navigate his way
to an elusive rainbow table.
