A Python 3 tool for analyzing XOR-encrypted data that can guess key lengths and decrypt XOR ciphers based on character frequency analysis.

A Python 3 tool for analyzing XOR-encrypted data that can guess key lengths and decrypt XOR ciphers based on character frequency analysis.
xortool.py is a Python 3-based cryptographic analysis tool designed for XOR cipher analysis and decryption. The tool provides two primary analytical capabilities for XOR-encrypted data. First, it can estimate the key length by analyzing the frequency of equal characters within the encrypted data, using statistical patterns to identify likely key sizes. Second, it attempts to determine the actual XOR key by leveraging knowledge of the most frequently occurring characters in typical plaintext. The tool operates through command-line interface and requires Python 3 for execution. Installation is available through pip package manager or can be built from source using poetry for development purposes. xortool.py is particularly useful for reverse engineering scenarios where XOR encryption has been applied to obfuscate data or code, making it a valuable resource for malware analysts and security researchers working with encrypted or encoded samples.
