Famous vulnerabilities in encryption: cases that marked history

Throughout digital history, several implementation failures have challenged trust in cryptography.

Featured cases

• Heartbleed (2014): allowed reading memory on OpenSSL servers.
• Logjam (2015): weakened the security of the TLS protocol.
• ROCA (2017): affected millions of poorly generated RSA keys.

What did we learn?

• The implementation is as critical as the algorithm.
• Continuous auditing is vital.
• Transparency (open source) strengthens security.

Conclusion

Even solid algorithms can fail if implemented poorly. Therefore, security must be a continuous priority.
