Kryptos Tools combines the best features of the previous two apps (Kryptos Tools - Vigenère and Kryptos Tools - Transposition) along with additional details, documents and photos consolidated into one great app. Kryptos Tools includes classic ciphers, like the Vigenère cipher, that was used to encrypt the first two sections of Kryptos (K1 and K2). It also includes the Transposition Matrix which provides a visual implementation of the Transposition cipher for solving Kryptos section K3. Kryptos Tools now contains sixteen (16) classic ciphers: * Affine * Atbash * Beaufort (plus Autokey variant) * Bifid * Caesar * Columnar Transposition * Four-square * Gronsfeld (plus Autokey variant) * Hill * One-Time Pad * Playfair * ROT13 (Rotate-13) * Substitution * Transposition Matrix * Trifid * Vigenère (plus Autokey variant) Additional ciphers and utilities will be added in future releases. Detailed solutions and information about these sections of the puzzle are also detailed within. Kryptos is a sculpture by the American artist Jim Sanborn located on the grounds of the Central Intelligence Agency (CIA) in Langley, Virginia. Since the dedication of Kryptos on November 3, 1990, the first three sections have been successfully decrypted. However, the fourth section remains one of the most famous unsolved codes in the world. Are you going to be the one to solve this mystery?
