  We have shown that GNUnet is vulnerable to rubber-hose cryptanalysis, but we additionally have presented an efficient content filter for GNUnet. If content filtering is legally enforced, censoring GNUnet is possible at a very large scale.

  Catherine scooted out of the way, giving Terry access to the keyboard. With a labored sigh, Terry began searching the encrypted text. “I could try a ciphertext-only attack,” he mumbled to no one in particular. “Then again,” he glared at the attacker and continued, “I could always try rubber-hose cryptanalysis.” He thought for a moment. “I don't need a total break; I'm only interested in information deduction. Let me check the swap file.”

  Other types of cryptanalytic attacks include chosen cipher text, chosen key, rubber hose cryptanalysis, and purchase key. Algorithms differ by degrees of security; this depends on how hard they are to break.
