Crypto vs Kryptos Tools

Dive into cryptography with Crypto. Use Caesar and Vigenère ciphers and encrypt and decrypt messages. CRYPTO Crypto allows you to encrypt and decrypt messages using Caesar and Vigenère ciphers. Create a message, select a key or a keyword, and then send the encrypted message to your friends. Similarly can you decrypt encrypted messages. CIPHERS In both Caesar and Vigenère ciphers, each letter is substituted with another, which makes them substitution ciphers. Only those who know the secret key are able to decrypt messages, though it is possible to decrypt an encrypted message without knowing the key by using brute force. CAESAR CIPHER In the case of Caesar’s cipher, we use a secret integral key (k). This secret key is used to rotate (i.e. shift) each letter by k places, wrapping A to Z and a to z as needed. For example, if we use the key of 1 to encrypt “Hello world!”, we will get “Ifmmp xpsme!” To decrypt this message, shift the letters backward. VIGENÈRE CIPHER Vigenère cipher improves upon Caesar cipher by shifting letters using different keys. This sequence of keys is known as a keyword. Each letter in the keyword represents by how far the corresponding letter in the original message will be shifted (A and a represent 0, B and b represent 1, Z and z represent 25). If we encrypt “Hello world!” with the keyword “Squirrel”, we will get “Zuftf nscdt!”

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?
