A cryptogram is a type of puzzle that consists of a short piece of encrypted text. [ 1] Generally the cipher used to encrypt the text is simple enough that the cryptogram can be solved by hand. Substitution ciphers where each letter is replaced by a different letter or number are frequently used. To solve the puzzle, one must recover the ...

Kryptos is a distributed sculpture by the American artist Jim Sanborn located on the grounds of the Central Intelligence Agency (CIA) headquarters, the George Bush Center for Intelligence in Langley, Virginia. [ 1] Since its dedication on November 3, 1990, there has been much speculation about the meaning of the four encrypted messages it bears.
Symmetric-key algorithms[ a] are algorithms for cryptography that use the same cryptographic keys for both the encryption of plaintext and the decryption of ciphertext. The keys may be identical, or there may be a simple transformation to go between the two keys. [ 1] The keys, in practice, represent a shared secret between two or more parties ...

The partially decomposed body of Ricky McCormick was discovered in a field in St. Charles County, Missouri on June 30, 1999. Sheriffs found two garbled hand-written notes – apparently written in secret code – in the victim's pockets, and these were handed over to the FBI for further investigation. Attempts by the FBI's Cryptanalysis and ...
Confusion in a symmetric cipher is obscuring the local correlation between the input ( plaintext ), and output ( ciphertext) by varying the application of the key to the data, while diffusion is hiding the plaintext statistics by spreading it over a larger area of ciphertext. [ 2] Although ciphers can be confusion-only ( substitution cipher ...
Polygraphic substitution is a cipher in which a uniform substitution is performed on blocks of letters. When the length of the block is specifically known, more precise terms are used: for instance, a cipher in which pairs of letters are substituted is bigraphic . As a concept, polygraphic substitution contrasts with monoalphabetic (or simple ...
