Encrypt plaintext by shifting letters by a user-defined number. Decrypt ciphertext back to the original text using the same shift. Input validation to ensure the shift is a valid integer.

The app takes a string and a numeric key, then shifts each character's Unicode value while maintaining the alphabet boundaries using the modulo operator.

Abstract: Cipher algorithm identification is a crucial prerequisite for cryptanalysis, aiming to infer the encryption algorithm solely from ciphertext. Existing methods often rely on single ...

Securing our information and our technologies has become critical in this shifting and uncertain geopolitical context.

Abstract: Block ciphers are designed to function as random mappings, making it essential for them to successfully pass statistical randomness tests. These tests evaluate whether the distribution of a ...

Sometimes an episode will give you nothing at all. You’ll sit through something that took hundreds if not thousands of people to make, and you’re left wondering: Is that all? But then comes a ...
