(Update -- Tuesday, 9/6/2011) We have posted the First Clue!
(Saturday, 9/3/2011)
Hey, everyone. It's been a while since you've heard anything from us on our blog. Some of you may have heard rumblings that we are expecting! It's true! In fact, we're expecting two little kiddos to enter our home sometime in the end of January or beginning of February 2012!
People keep asking us what we're having. I tell them it's an iguana. Two of them. Probably. BUT, if you really want to know the gender of Johnson Babies #1 and #2, keep checking this blog post for the next week or so.
Immediate family members will soon be receiving a package from us via US Postal Service. Please leave a comment here indicating when you have received the package. If you can't leave a comment for some reason, then go ahead and send us an email ( aubzilla[at]hotmail.com ), call us, text us --- whatever. Just so we know that you received it.
Stay Tuned! (Bookmark this page.)

"Why can't you just tell us what you're having?”
Those of you who received a package from us in the mail, and more especially the grandmas, are probably impatiently wondering what on earth two laminated paper disks, circularly inscribed with the alphabet and pinned to a corkboard, are going to tell you about the genders of our two growing kiddos.
Nothing at all! Great joke, right?
OK, at least they won't tell you anything without some extra information (which you will receive soon enough.)
You see, for thousands of years, people have sometimes needed to keep things secret from prying eyes. You know, battle plans, the identity of double agents, the genders of new grandchildren, and the like. So, people started writing things down in sneaky ways.
One of these methods of obscuring the true meaning of a text was called the "Vigenere Cipher," named after a Frenchman who didn't actually invent this cipher (although he DID invent a BETTER cipher for which he did NOT receive credit.) The cipher goes something like this:
- Shift the alphabet by a certain number of letters. This can be any number, up to 26. For example, let's say that we shift the alphabet by 4 letters. Then, A becomes D, B becomes E, C becomes F, and so forth. We could call this specific shift length (4) a "D" shift (since D is the fourth letter of the alphabet, and the letter to which "A" will be mapped.)
- Using this new substitution alphabet, write down the first letter of the text that you want to encrypt.
- Repeat steps 1 and 2 for all remaining letters of your text, choosing a different shift length for each letter.
Let's work through an example. Assume that someone wants to encrypt the message, "WE_EAT_BEES" (because they clearly do not want people to know that they eat bees.) To encrypt this message using the Vigenere cipher, one must write the message while shifting the alphabet, using a different shift length for each letter of the message.
Above, I mentioned that we can describe an alphabet shift using a letter (e.g., a shift length of 4 could be called a "D" shift.) This means, that we can choose a secret key word (like "GROSS") to represent a sequence of shifts of different lengths. The letters G-R-O-S-S would represent shift lengths of 7, 18, 15, 19, and 19, respectively.
(A "G" shift - 7)
plaintext: ABCDEFGHIJKLMNOPQRSTUVWXYZ_
encrypted: GHIJKLMNOPQRSTUVWXYZ_ABCDEF
(An "R" shift - 18)
plaintext: ABCDEFGHIJKLMNOPQRSTUVWXYZ_
encrypted: RSTUVWXYZ_ABCDEFGHIJKLMNOPQ
(An "O" shift - 15)
plaintext: ABCDEFGHIJKLMNOPQRSTUVWXYZ_
encrypted: OPQRSTUVWXYZ_ABCDEFGHIJKLMN
(An "S" shift - 19)
plaintext: ABCDEFGHIJKLMNOPQRSTUVWXYZ_
encrypted: STUVWXYZ_ABCDEFGHIJKLMNOPQR
Essentially, we have come up with 4 different alphabets (one for each letter in "GROSS," with "S" appearing twice) to use for encrypting our text. Let's try it! We'll start out by aligning the keyword 'GROSS" with our secret message "WE_EAT_BEES." The keyword will repeat itself, because it is shorter than our message. After we align them, it should look like this:
keyword: GROSSGROSSG
plaintext: WE_EAT_BEES
We can then encrypt the plain text, using the 4 different alphabets we laid out earlier. So, the first letter of our message, "W", would become "B" in the "G" alphabet. The second letter, "E", would become "V" in the "R" alphabet. The third letter of our message, "_" (the underscore), would become "N" in the "O" alphabet. We finish writing out the message using our shifted alphabets, until we end up with the following encrypted text:
keyword: GROSSGROSSG
plaintext: WE_EAT_BEES
encrypted: BVNWSZQPWWY
If it's not clear how we ended up with this encrypted text, go look through the 4 alphabets (G, R, O, and S alphabets) and walk through the process step by step. You'll get it with some practice!
Now, what if we want to DECRYPT some encrypted text? Well, just line up the encrypted text with our key word again, like this:
keyword: GROSSGROSSG
encrypted: BVNWSZQPWWY
Then, work the process in reverse! An encrypted "B" becomes "W" in the "G" alphabet. An encrypted "V" becomes "E" in the "R" alphabet, and so forth!
keyword: GROSSGROSSG
encrypted: BVNWSZQPWWY
plaintext: WE_EAT_BEES
Now, what about the corkboard with the two alphabet discs pinned to it? Well, it's an encoder/decoder ring! It allows you to quickly and easily shift the alphabet by different amounts while you are encoding/decoding a secret message! Isn't this awesome? Yes! We KNEW you would love it!
So, if you have the following three things, you can figure out what the gender of our baby will be:
- An encrypted message (like "BVNWSZQPWWY")
- A secret key word (like "GROSS")
- An encoder/decoder ring
Follow the blog for the next few days, and we'll give you the encrypted messages, plus the keywords. Using this with the decoder ring, you'll be able to find out what we're having! (Hint: they are not iguanas.)
