Kryptos

Kryptos the greek word for "hidden" is a mysterious sculpture by artist Jim Sanborn, an American artist, collaborated with retired CIA cryptographer Edward Scheidt to create this sculpture. The artwork has captivated cryptanalysts and puzzle enthusiasts since its installation on Nov 3 1990 at the CIA headquarters in Langley, Virginia. This enigmatic artwork is renowned for containing a complex encrypted message. It features four encrypted messages, referred to as K1, K2, K3, and K4. The first three parts have been solved, but K4 remains one of the most famous unsolved codes in the world. K4 consists of 97 characters and has resisted all attempts at decryption. The difficulty in solving K4 stems from several factors:

Length: With only 97 characters, it provides a limited amount of data for cryptanalysts to work with. This brevity makes it challenging to find patterns or employ statistical analysis effectively.
Modified Cryptographic Techniques: While the first three parts were solved using traditional cryptographic techniques, it's unknown whether K4 follows the same methods or if involves customized cryptographic techniques.
Multiple Techniques: Most likely contains 2 or 3 cryptographic techniques in series, making it exponentially harder to crack.
Purposeful Mistakes: As in previous section Sanborn has inserted errors into his text to increase the difficulty.

Description:

The main part of the sculpture is located in the northwest corner of the courtyard, It is comprised of 4 large copper plates arranged together to form an S-shaped screen resembling a scroll. Kryptos contains a total of 1736 characters, the left side contains 869 letters which make up the encrypted text while the right side comprises a keyed Vigenere encryption tableau with 867 letters. All characters are from the standard latin alphabet and 4 question marks all within the encryption side.

When Jim Sandborn built Kryptos he also placed other smaller pieces of art around the CIA headquarters which may be related to the main sculpture, these include several large granite slabs with copper pieces with morse code messages printed on them. Another slab with a compass engraved in it pointing to a nearby lodestone that is east northeast of the compass. He also built some more landscape pieces of art which includes a fish pond with two opposing benches, a reflecting pool and a triangle black stone slab.

Ed Scheidt

Sanborn received help developing the cryptographic techniques used in Kryptos from Ed Scheidt who retired from the CIA in December 1989 as chairman of the CIA office of communications,

Previous Solutions

Jim Gillogly in 1999 was the first person to publicly state that he had solved K1, K2, & K3, he was a computer scientist from California, he used his computer to solve them.

The CIA revealed that their analyst David Stein had solved them using only pencil and paper in 1998, but was not public released until Jim Gillogly announcement.

but really tho this si a long text test

To find out the word and character count of your writing, simply copy and paste text into the tool or write directly into the text area. Once done, the free online tool will display both counts for the text that's been inserted. This can be useful in many instances, but it can be especially helpful when you are writing for something that has a character minimum or limit.

Character and word limits are quite common these days on the Internet. The one that most people are likely aware of is the 140 character limit for tweets on Twitter, but character limits aren't restricted to Twitter. There are limits for text messages (SMS), Yelp reviews, Facebook posts, Pinterest pins, Reddit titles and comments, eBay titles and descriptions as well as many others. Knowing these limits, as well as being able to see as you approach them, will enable you to better express yourself within the imposed limits.

For students, there are usually limits or minimums for homework assignments. The same is often true
