Which TLS/cryptography analyzer is right for you?

Exploiting the computationally expensive nature of the Diffie-Hellman key exchange protocol an attacker can perform a denial-of-service (DoS) attack by sending arbitrary numbers as…

Conclusion "The DHEat attack remains viable against most SSH installations, as default settings are inadequate at deflecting it. Very little bandwidth is needed to cause a dramatic…

We factorize a 48-bit integer using 10 trapped-ion qubits on a Quantinuum’s quantum computer. This result outperforms the recent achievement by B. Yan et al., arXiv:2212.12372 (202…

Chinese researchers claim that there is an existing algorithm that, even with today's quantum computers, makes it possible to break the RSA algorithm. At the same time, there are d…

... The CVE-2002-20001 (a.k.a DHEat attack) vulnerability inherent to the support of the Diffie-Hellman (DH) and Elliptic Curve Diffie-Hellman (ECDH) key exchanges in TLS and other…

You can also use CryptoLyzer[1] to audit your TLS (not just HTTPS, but SMTP, IMAP, ...) and SSH servers if you do not want to use SaaS solutions. There are another tools (open sour…

All the revocation checking mechanism have their pitfalls. It is a so complex issue. CRL has a very important benefit, namely it can be prefetched and can be updated regularly whic…
