🔐 Cipher Algorithm Detector

A Python tool that predicts the encryption algorithm used for a given ciphertext based on format, length, and entropy analysis.

🚀 Features

• Detects Hex/Base64 encoding.
• Calculates entropy to estimate randomness.
• Predicts AES, DES, 3DES, RC4, RSA, and ECC.
• Provides detailed analysis with entropy score.

  Tools & Libraries Used

Python – Core programming language for the script. Base64 – Used to detect and decode Base64-encoded ciphertexts. Re (Regex Module) – Helps validate hexadecimal and Base64 formats. Math – Used for entropy calculation (Shannon entropy formula). Collections (Counter) – Counts frequency of bytes to compute entropy. numpy, Pandas, Tensorflow, cryptography...............
