RsaCtfTool vs xxexploiter: 2026 Comparison
RsaCtfTool is a free penetration testing tool. xxexploiter is a free penetration testing tool. Compare features, ratings, integrations, and community reviews side by side to find the best penetration testing fit for your security stack.
CST VerdictBased on our analysis of available product data, here is our conclusion:
Penetration testers and security researchers validating RSA implementations should reach for RsaCtfTool when you need to quickly expose weak key generation in legacy systems; its multi-algorithm factorization approach catches common mistakes that single-method tools miss. With 6,830 GitHub stars and active community contributions, it's the go-to for CTF competitions and authorized assessments of systems you control. Skip this if you're looking for a general cryptanalysis platform covering symmetric ciphers or modern elliptic curve vulnerabilities; RsaCtfTool is RSA-specific and won't help there.
Penetration testers validating XXE patch coverage across legacy applications will find xxexploiter invaluable for its speed; you craft the payload once and iterate across dozens of endpoints without rebuilding exploitation logic each time. The free price point and 565 GitHub stars indicate it's proven in real assessments, not theoretical. Skip this if your scope includes modern APIs or frameworks that reject malformed XML outright; xxexploiter assumes you're already past basic input validation and targeting systems with actual parsers.
