顯然,制定這樣一個法規,嚴格監控密碼學研究和使用,不過是為公權力在想要時窺探秘密、侵犯私益的行為創造便利。從這個立法目的出發,我們可以得出這樣的結論:只要試圖從國家眼皮底下藏住東西的都要被這規定製裁。你說軟體不能沒收?你說非對稱加密的信息你也不知道怎麼解開?你問我「產品」是什麼意思?We are totalitarian, we do whatever we want, WHO FUCKING CARES.
Shortly after its release, PGP encryption found its way outside the United States, and in February 1993 Zimmermann became the formal target of a criminal investigation by the US Government for "munitions export without a license". Cryptosystems using keys larger than 40 bits were then considered munitions within the definition of the US export regulations; PGP has never used keys smaller than 128 bits so it qualified at that time. Penalties for violation, if found guilty, were substantial. ... Zimmermann challenged these regulations in an imaginative way. He published the entire source code of PGP in a hardback book, via MIT Press, which was distributed and sold widely. ... PGP would thus be available anywhere in the world. The claimed principle was simple: export of munitions—guns, bombs, planes, and software—was (and remains) restricted; but the export of books is protected by the First Amendment.
