Migrating CRL Workflows from Bouncy Castle to wolfSSL JNI
If your Java stack currently uses Bouncy Castle for certificate tooling, moving CRL generation to wolfSSL’s JNI is straightforward once you map the flow correctly. wolfSSL JNI/JSSE uses wolfSSL’s native C crypto/TLS library, so projects can share one crypto implementation across Java and non-Java components. In environments that require validated...Read more -
Expanded CRL Support: Generating a CRL
wolfSSL has long provided solid CRL decode and validation support. This update builds on that foundation by adding CRL generation and signing capabilities, along with certificate extension helpers that improve revocation-aware certificate creation workflows.Read more -

wolfSSL’s OCSP and OCSP-Stapling Support
Sometimes, X.509 certificates need to be revoked. One way that can happen is via CRL (Certificate Revocation List), but that’s a topic for another time. Today we’ll focus on OCSP (Online Certificate Status Protocol). The OCSP protocol is designed to allow a client to send a real-time query to a...Read more -
Keeping TLS 1.3 AES-GCM Session Keys Out of RAM
Secure Element Offload via Crypto Callbacks in wolfSSL Modern embedded and security-critical systems increasingly rely on Secure Elements, TPMs, and hardware cryptographic accelerators to protect private keys. In wolfSSL, asymmetric keys such as ECC private keys can already reside entirely inside hardware using Crypto Callbacks. Until now, however, TLS 1.3...Read more -
