Golden-Alice

Just like every end of year, I am awarding the Golden Alice for outstanding achievements in the field of crypto history.

Starlight-Steganogram-bar

The last crypto challenge I’m going present in 2016 was created by master-codebreaker Tony Gaffney. Can you solve his starlight steganogram?

Friedman-Music-bar

Forget about all the Christmas carols! Here comes the Friedman’s musical cryptogram from 1933, as played by a scorewriter.

Postcard-Borges-Christmas-1906-bar

Klausis Krypto Kolumne wishes everybody a Merry Christmas! In case you find some spare time over the holidays, try to solve this encrypted Christmas card from the early 20th century.

Merry-Christmas

William Friedman and his wife Elizebeth not only were great codebreakers, but they also were creative and had a sense of humour. This can be seen from the Christmas cards they devised in the 1920s and 1930s.

Postcard-Moga-bar

In 1905 a woman named Elena Moga received an encrypted postcard. Can a reader break this cryptogram?

Enigma-m4-bar

Enigmas are getting more and more expensive. In New York, a four rotor naval Enigma has now sold for almost half a million dollars.

Friedman-Bacon-Castle-bar

William Friedman, one of the most notable cryptologists in history, used a 16th century stegnography system to hide messages in pictures. Some of his codes are hard to decrypt. Maybe a reader can help.

CSO-2-bar

After 20 years in the IT security business, I have now created a comic strip based on my experiences. I guarantee that all the stories told in it are true.

Foley-bar

Frank Foley, a British secret agent operating in Nazi Germany, saved many Jewish people from the holocaust. In the British National Archives, I found an unusual encryption method that was (probably) used by one of his men.
