Most TLS libraries leave your certificates and private keys sitting in RAM long after they’re used — a jackpot for attackers with memory access. wolfSSL is the only TLS library that gives you the power to erase them completely with the wolfSSL_UnloadCertsKeys API. This function doesn’t just free memory — it securely zeroes out every byte of your sensitive data, ensuring nothing remains to be stolen.
From IoT devices and payment terminals to aerospace, automotive, and defense systems, wolfSSL_UnloadCertsKeys helps you meet the toughest security and compliance requirements. Combined with wolfSSL’s FIPS 140-3 validated cryptography, you get end-to-end protection: strong encryption for data in transit, and proactive memory sanitization for keys at rest in RAM. This synergy reduces your attack surface, thwarts memory dump attacks, and helps satisfy stringent standards like GDPR, HIPAA, and PCI DSS.
With wolfSSL, you’re not just encrypting traffic — you’re safeguarding the secrets behind it.
