This skill is a local Node.js script that implements a custom triple-XOR cipher. Before installing or using it: - Do not treat this as strong cryptography. XOR-based schemes are weak compared to standard primitives (AES-GCM, ChaCha20-Poly1305). The SKILL.md even warns it is not a substitute for professional crypto. Avoid using it for high-value secrets. - The package metadata lists 'openssl' as a required binary but the code never calls openssl — this is unnecessary and unexplained. Ask the author why openssl is required or remove that dependency. - The code has bugs: splitKey can produce an empty third key when key length is divisible by 3, which will cause a crash (modulo by zero). Test thoroughly and prefer a patched implementation before trusting it. - The script prints decrypted metadata to stderr, which can leak filenames and mime types; if that is sensitive, modify the script to avoid printing metadata or ensure stderr is not exposed. - There's leftover/simplified code paths and unused functions in the file (unused encrypt() earlier), suggesting the implementation is unfinished. Prefer a maintained, audited library or a minimal, clearly implemented tool. If you decide to proceed: run the tool only on non-sensitive test data first, review and fix the key-splitting bug, remove the spurious 'openssl' requirement, and consider migrating to well-reviewed cryptographic libraries for real secrecy needs.
