secure-vault

This skill/document describes a local-only CLI vault whose purpose aligns with the described capabilities. The main security concerns are design-level: XOR encryption is cryptographically weak and there is no mention of authentication/integrity or robust key derivation; the 'secure deletion' claim is unreliable in many filesystems; the local key file centralizes risk if the host or backups are compromised. The documentation does not show network exfiltration vectors or credential-harvesting behavior. Without the implementation code, we cannot confirm whether additional malicious behaviors exist. Overall: functional fit is good but cryptographic choices and deletion claims make this unsuitable for high-value secrets without code changes and stronger crypto.
