CryptoNets is a demonstration of the use of Neural-Networks over data encrypted with Homomorphic Encryption. Homomorphic Encryptions allow performing operations such as addition and multiplication over data while it is encrypted. Therefore, it allows keeping data private while outsourcing computation (see here and here for more about Homomorphic E

Vigenère-Cipher-Decrypter is a program that attempts to decrypt certain data encrypted by the Vigenère cipher. This tool can decrypt Vigenère cipher with and without Key
