CTF-CryptoTool is a Python-based utility designed for deciphering encrypted text encountered in Capture The Flag (CTF) challenges by employing brute-force techniques across a comprehensive array of known ciphers, encodings, and obfuscators. It allows users to input cipher text and optional keys to facilitate decoding, making it particularly useful for cryptanalysis tasks where keys may be unknown. Notable features include support for multiple ciphers such as Caesar, Vigenere, and various encoding formats like Base64 and Hex.
