A simple web-based tool to decrypt Caesar Cipher text. The tool tries all possible shifts (from 1 to 25) and returns all potential decrypted texts, sorted by the number of matching words from a ...

:return: The function `multiplicative_inverse(a)` returns the modular multiplicative inverse of `a`. If a modular multiplicative inverse exists, it returns that value ...

Abstract: The encryption techniques convert plaintext or original image into cipher text or cipher image. Here we are adding the pseudorandom values to the corresponding pixels of the image and we are ...

Abstract: With the shift in storage paradigm, there is an increasing need for privacy of dataset and also for an encryption scheme that permits computation on encrypted data. Paillier cryptosystem is ...
