Thomas Jefferson Used Encryption

The encryption of computer data is one of the most powerful tools individuals have to protect themselves against an intrusive state.

Encryption is the process of converting data into encoded text produced by an algorithm. To convert the encoded text back to its original form requires either a ‘key’ or tremendous effort. A key is a sequence of numbers that senders typically offer to those they wish to decrypt the protected data. All others must use the ‘tremendous effort’ option.

The state wants to be a universal key holder. Otherwise, people could transmit everything from love letters to financial data in a secure and private manner that escapes surveillance. The state argues that encryption offers new and unique protection for terrorists, tax evaders, drug dealers, pedophiles and other miscreants. And, so, new and unique measures must be taken to pull back the dangerous veil of cyber privacy.

Nonsense. Encryption is almost as old as communication itself. The root word “cryptography” comes from two ancient Greek words: “crypto” or “hidden”; and, “graphia” or “writing.” Encryption’s main purpose is to shield information from those who would use it in an unwanted manner.

Knowledge has always been power and those who seek power have always commanded or censored access to knowledge, depending on which action gave them advantage.

In America, the tug of war between privacy and forced access to encrypted data is as old as the nation’s formation. As always, forced access was executed by authorities against individuals.

In 1785, a resolution authorized the secretary of the Department of Foreign Affairs to open and inspect any mail that related to the safety and interests of the United States. The ensuing inspections caused prominent men, like George Washington, to complain of mail tampering. According to various historians, it also led James Madison, Thomas Jefferson and James Monroe to correspond in code. That is, they encrypted their letters to preserve the privacy of their political discussions.

The need for Founding Fathers to encrypt their correspondence is high irony. The intrusive post office against which they rebelled had been established specifically to provide a free flow of political opinion. In the 1770′s, Sam Adams urged the 13 colonies to create an independent postal system because the existing post office, established by the British, acted as a barrier to the spread of rebellious sentiment. Dorothy Ganfield Fowler in her book Unmailable: Congress and the Post Office observed, “He [Adams] claimed the colonial post office was made use of for the purpose of stopping the ‘Channels of publick Intelligence and so in Effect of aiding the measures of Tyranny.’”

Alas, the more government changes, the more oppression remains the same. Soon the Continental Congress itself wanted to declare some types of matter ‘unmailable’ because their content were deemed dangerous. Anti-Federalist letters and periodicals became one of the first types of information to become de facto unmailable. (Anti-federalists resisted centralized government and rejected a Constitution without a Bill of Rights.) During the ratification debates on the Constitution, the Anti-Federalists were unable to circulate their material through the Federalist-controlled post office.

Throughout history, encryption and the control of information has been particularly important during times of war. Prior to and during the Civil War, for example, both the North and South banned just about everything deemed to be ‘seditious.’ Private communication in America has never recovered. Recent history is rife with purely political postal measures such as the “Cunningham Amendment” (1962) which restricted the circulation of communist literature that originated in a foreign country.

The American government has always realized the political importance of controlling the flow of information. In the 1770s, communication occurred primarily through postal routes maintained by horseback riders. Today, we communicate through packets of data beamed across phone lines; the internet is the modern equivalent of the Pony Express. The difference in the transmission mode is irrelevant to the political principles involved. The key questions are, “who owns your personal information?” and “who has the right to access it?”

On May 6, 1999, the Ninth Circuit Court of Appeals offered answers. The court ruled that federal restrictions on encryption violate the First Amendment: specifically, they constitute prior restraint and may limit the freedom of the press (Daniel J. Bernstein v. US Department of Justice).

In the decision, Judge Betty Fletcher stated, “The availability and use of secure encryption may…reclaim some portion of the privacy we have lost. Government efforts to control encryption thus may well implicate not only the First Amendment rights…but also the constitutional rights of each of us as potential recipients of encryption’s bounty.”

Since then, the government has sidestepped the ruling, sometimes quietly, sometimes under the aegis of other laws. For example, the Clinton Administration required a one-time technical review of encryption software as a precondition to its export.

Such maneuvers are not a new response to a new threat. They are the same tactics of which George Washington complained, the same ones that drove Thomas Jefferson to use code.

    JdL: I will look into steganography. I was unaware of it…so thanks for that!

    Patrick Lee: Good link!

    Excellent and right on target. One thing I would add is that with steganography (which conceals the fact that there’s data hidden in a music file, image file, etc.) one can finesse the question of whether the government demands encryption keys for everything. Use of steg does multiply the amount of data that must be transmitted for a given amount of encrypted information, but nowadays bandwidth is pretty cheap, so unless the encrypted data is huge, the additional bytes shouldn’t present a serious problem.

    People often cite TrueCrypt with its hidden volume-within-a-volume, but I don’t consider it true steganography, as the fact that encryption is going on somewhere is laid bare, and government thugs might just ASSUME that there’s another volume hidden within the first. I’ve written my own programs to stuff data into .wav and .bmp files; with these I can plausibly say “What encryption?” if asked.

    One of Thomas Jefferson’s blog posts dealt with his use of a secret code. Read it at
    http://thomasjeffersonleadership.com/blog/thomas-jefferson-on-using-a-secret-code/
    That post also contains a link to a delightful Wall Street Journal on a cipher AND practical joke that eluded Jefferson for the last 25 years of his life. It wasn’t solved until 2009!

    Excellent article! Thank you for reminding us of this important lesson from history, Wendy!

    I had known that Jefferson was interested in and made use of cryptography, but had presumed it probably dated to the Revolutionary Period or his period as Ambassador to France — I had not realized that he had also needed it to protect himself against American “Counter-Revolutionary” witch hunts a mere 9 years after the Revolutionaries criticized the British for doing the very same thing! :-(

    Guess it’s once again true: “Meet the new boss — same as the old boss.” And “The more things change, the more they stay the same”… :-(

    It is good to see some push back at the ever encroaching state into our private lives. Whether I am discussing a possible business venture, or Aunt Mabel’s apple pie recipe, there is a right to and expectation of privacy between myself and those with whom I am communicating. Sadly those in power never see it this way, except for their own communications.

    If we were all privy to the private communications of those in power, the illusion of decency as well as the illusion of “self-government” would both be shattered.

    When discussing matters of morality, we need only seek justification for those actions that harm others, but the powers that be have turned this around so that we must try to justify all of our peaceful actions without regard to the harms that such requirements cause or the fact that they are denying basic respect for persons and personhood.

    Treating every person like the teenager passing notes in class denies them their inherent moral worth, which is sufficient cause to condemn these efforts to deny to us our privacy and our ability to converse with those we desire without fear or repercussions.

    Thanks for the history lesson and great article!
