Today I’m going to introduce two encrypted postcards I have recently found on a postcard blog. They are completely different from each other, but both still wait to be solved.
As I pointed out in many earlier posts, Google is by far my best source for finding interesting material for this blog. Sometimes I even find several crypto stories on one page. Exactly this happened when Google led me to a site named Cipherface, hosted by the microblogging and image sharing platform Tumblr.
At first view, Cipherface is a simple collection of images and statements about cryptography and related topics. When you register at Tumblr and log in, you get additional information about the images, including reader comments. Many of the pictures look quite interesting to me. Some represent solved or unsolved cryptograms – exactly the stuff I’m looking for for Klausis Krypto Kolumne.
I have no idea who the creator of Cipherface is. As it seems, no personal information about him or her is available on the site.
A postcard from London
One of the Cipherface pictures shows an encrypted post card.
This postcard was taken from an article published by Alan Petrulis on the blog, MetroPostcards, on May 9, 2016. Most encrypted postcards I’m aware of were sent by young men to their loved women. I suppose that this one is not an exception. On the post stamp the word “Barnes” can be read, which is a district of London.
The alphabet used consists of groups of long and short lines. My first impression is that each group stands for a letter of the Morse code. If this is the case, the text starts with PEACH.
A postcard from Chicago
The same article provides another encrypted postcard:
This one is dated 7/10/97, which probably means July 10, 1897. The only cleartext word I can spot is “Chicago”, which is presumably the place from where the card was sent. There’s probably no relationship between this card and the one above.
Can somebody make sense of these two encrypted postcards? Any hints and solutions are appreciated.
