CaRT Neutering Format Library

Compressed and RC4 Transport (CaRT) is a file format and an associated Python library used to 'neuter' files for secure distribution, particularly in the malware analysis community. It encrypts and compresses files, optionally embedding metadata, to prevent execution and detection by antivirus software.
