Post-Quantum Cryptography Audit Tool QSafe Released: Detecting Hidden Weaknesses in Encryption Implementations

Israeli cybersecurity company QShield released the open-source cryptographic audit tool QSafe on February 26. The tool specifically detects weaknesses in cryptographic implementations that quantum computers could exploit — not mathematical algorithm flaws, but side-channel leakage, timing attack windows, and predictability in pseudorandom number generators within code implementations.

QSafe has conducted comprehensive audits of 15 mainstream cryptographic libraries including OpenSSL and BoringSSL, discovering 37 previously unknown potential weaknesses. Four were rated as high severity, involving entropy deficiency issues in key generation processes. All findings have been reported to relevant maintainers through responsible disclosure.
