The cryptographer Boris C. W. Hagelin (1892-1983) created 1952 the company Crypto AG, in Schweiz. In 1995 the company sued Mr. Buehler, its fired salesman, who in a book claimed that Crypto AG had built-in a backdoor to NSA in their encryption machines. Just a few days before engineers were to testify, the suit was withdrawn and the parties agreed to not disclose the settlement. This backdoor should have been implemented since 1957. Hans Buehler lives today in Switzerland and can be reached through interviews but the secret settlement may limit his answers to some questions.
Crypto AG is still active today. For example they have an advertise titled; Information Security from one source -Crypto AG in Defence & Security Review 1997. In a press release dated December 05, 1997 ”Facts and Fiction about Crypto AG in the Internet” they write:
”Internet is open for all sorts of information – unfortunately also for disinformation. Some webmasters construct links to defamatory articles and rumours containing untrue statements about our company and try to give credence to them by means of links to the Crypto-Internet address.”
”For at least half a century, the US has been intercepting and decrypting the top-secret documents of most of the world’s governments. … It may be the greatest intelligence scam of the century: For decades, the US has routinely intercepted and deciphered top-secret encrypted messages of 120 countries. These nations had bought the world’s most sophisticated and supposedly secure commercial encryption technology from Crypto AG, a Swiss company that staked its reputation and the security concerns of its clients on its neutrality. The purchasing nations, confident that their communications were protected, sent messages from their capitals to embassies, military missions, trade offices, and espionage around the world, via telex, radio, teletype, and facsimile. ”

The article do also have these interesting news:
”The NSA allegedly received support from cryptographic companies Crypto AG and Gretag AG in Switzerland,Transvertex in Sweden, Nokia in Finland, and even newly privatized firms in post-Communist Hungary.39 In 1970, according to a secret German BND intelligence paper, supplied to the author, the Germans planned to ”fuse” the operations of three cryptographic firms-Crypto AG, Grattner AG (another Swiss cipher firm), and Ericsson of Sweden.”
- Transvertex existed as a swedish crypto company during World War 2.
Source: This is mentioned in a single meaning in the book; ”Svenska Kryptobedrifter”, page 108, ISBN 91-0-056229-7.
- Transvertex is also mentioned in an article titled;
”Swedish HC-9 Ciphering Machine” in Volume XIII Number 3 (July 1989) issue of the quarterly journal Cryptologia. The article on the cryptomachine was introduced with the following words:
”The HC-9 is a post World War II mechanical ciphering machine manufactured by AB Transvertex in Sweden and probably used by the Swedish military forces up to the 1970′s. The machine was designed for relatively low-level use; platoon, company, up to battalion levels and in regimental and brigade staffs…”
Source: (Torbjörn Andersson) and his
- rumours say that Transvertex was incorporated into Ericsson.
It seems hard to believe that Sweden’s military defence would create a backdoor in their own chipers to NSA.

”In answer to charges of machine-rigging, Crypto filed suit last year against Mr. Buehler, its fired salesman. The suit was settled last month, days before former Crypto engineers were to testify that they believed the machines were altered. The parties agreed not to disclose the settlement…. ”Spy sting: Few at the Swiss factory knew the mysterious visitors were pulling off a stunning intelligence coup — perhaps the most audacious in the National Security Agency’s long war on foreign codes; NO SUCH AGENCY .

Crypto AG is also mentioned in the book puzzle palace. Published in 1983, in it says:
- [by NSA in 1957]
was most likely expressed over the possible changes in the crypto systems of Britain and the other NATO countries because of the wide-spread feeling that America has broken their codes. The situation was complicated by the fact that newer, more complex cryptographic devices were being produced in Europe, devices that could set NSA code breakers back many years….
- [In august 1957, William F. Friedman was appointed to] ”
undertake a series of ultra sensitive missions .. These missions, the details of which are still considered top-secret by the agency…
- [was to]
establishing some sort of agreement with Europe’s largest manufacture of cryptographic devices, Crypto AG. … In 1957 Crypto AG was to cryptography what General Motors was to Automobiles. … the company was probably the world’s largest supplier of crypto equipment to foreign governments. Third world nations began casting off the chains of colonialism, they turned to Crypto AG to protect their secret communications. Heading the company was sixty-five-year-old Boris Caesar Hagelin, a russian born Swede who since the 1920 had been manufacturing crypto equipment and selling to various governments….
- [Friedman met Hagelin]
Exactly what happened during their meetings may newer be known, but it seems likely that some sort of ”deal” was offered to Hagelin by Friedman on behalf of NSA. What this deal may have involved can be only speculation, but it appears likely that Hagelin was asked to supply to the NSA details about various improvement and modifications made to the cipher machines his company supplied to other governments, including, especially, the members countries of NATO. This would have greatly shortened the time needed by the United States to break their code system. Evidence of this can be found in a worried request made by the NSA to the British author Ronald Clark who wrote a biography of Friedman in 1977. In his book
- [ The book mentioned here is according to the puzzle palace's reference list, reference 310: "Should you approve": Ronald Clark, "
The man who broke purple
- " (Boston: Little. Brown, 1977) pp. 153-154]
Clark made several references to Friedman’s 1957 trip
On learning Clark’s intention to mention these trips, officials of the NSA approached him and expressed their ”serious concern” about what might be revealed. They made a several unsuccessful attempts to read the manuscript…
the officials reluctantly explained to him that their reason for worry was that ”the book might discuss the supply of cipher machines to NATO; and that would deprive NSA of the daily information enabling the NSA to read the secret messages of other NATO countries”
Other sources – not found/received
- The Swiss newspaper ”Neue Zuercher Zeitung”, may 12, 1993 Page 11, 28, is rumoured to contain an article about Hans Buehler
- The journal; ”Journal De Geneve” (JG), March 10, 1993, Page 17, is also supposed to contain an article about Hans Buehler. However, i have not succeeded to even find the journal on the web.
- There should exist a tape recording from a radio program, 80 minute long, about the Buehler case that were broadcasted by the Swiss Radio International on May 15, 1994 and July 18, 1994. It would be nice to make a transcription and translate it into english text. Reference 5, in the article ”NSA, Crypto AG, and the Iraq-Iran Conflict” use the broadcast as a reference to this information:
”Swiss television traced the ownership of Crypto AG to a company in Liechtenstein, and from there back to a trust company in Munich. A witness appearing on Swiss television explained the real owner was the German government–the Federal Estates Administration.”
Information from Bill Payne:
Bill Payne says that he received the tape in 5 January 1995. It was sent to him from Hans Buehler.
