From Caesar ciphers to AES and RSA, Practical Microcontroller Cryptography shows how cryptography actually runs on ...

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

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.

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 ...

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 ...

Abstract: This paper provides a detailed comparative analysis. Of the main symmetric-key block cipher algorithms, including DES, 3DES, AES, Blowfish, Twofish, Serpent, IDEA, and RC6. It evaluates the ...
