Affected Users: Users of wolfSSL builds that use the C implementation of Curve25519 for private key operations. This does not affect builds using assembly-optimized implementations (ARM or Intel), the small footprint Curve25519 build, or hardware offload implementations. Summary: A potential side-channel vulnerability was identified in the C implementation of Curve25519 private key operations in wolfSSL. […]

PKCS#12 Support Enhancement: AES Encryption for Keys and Certificates
wolfSSL 5.8.2 has enhanced the wc_PKCS12_create() function to support modern AES encryption algorithms for PKCS#12 files. This update enables stronger security for protecting private keys and certificates. What Changed PKCS#12 files are commonly used to store cryptographic objects like private keys, certificates, and certificate chains. wolfSSL 5.8.2 supports modern AES encryptions for PKCS#12 instead of […]

Read MoreMore TagML-DSA OpenSSL Interoperability
The latest enhancement to wolfSSL’s ML-DSA (Module-Lattice-Based Digital Signature Algorithm) implementation solidifies interoperability with OpenSSL-generated cryptographic keys. This update introduces support for importing ML-DSA private keys that have been encoded using OpenSSL’s DER format. The new functionality extends the ASN.1 parsing logic to recognize and correctly decode an ASN.1 encoding structure that OpenSSL uses for […]

As the cybersecurity landscape prepares for the advent of quantum computing, the Trusted Platform Module (TPM) ecosystem is evolving to meet these new challenges. wolfSSL is proud to announce that wolfTPM now includes initial support for the TPM 2.0 Library Specification v1.85, bringing Post-Quantum Cryptography (PQC) capabilities to your hardware-backed security workflows. This update introduces […]
Read MoreMore TagVulnerability Disclosure: wolfSSL CVE-2025-7394
Affected Users: Applications using wolfSSL’s OpenSSL compatibility layer before wolfSSL version 5.8.2 that call both RAND_bytes() and fork() operations. This does not affect internal TLS operations or applications that do not explicitly use RAND_bytes(). Summary: A vulnerability was discovered in wolfSSL’s OpenSSL compatibility layer where the RAND_poll() function was not behaving as expected, leading to […]
Read MoreMore TagVulnerability Disclosure: wolfSSL Fault Injection Attack on ECC and Ed25519 Verify Operations
Affected Users: Users performing ECC or Ed25519 signature verification operations on devices that may be susceptible to fault injection attacks, particularly in security-critical applications such as secure boot implementations. Summary: A potential vulnerability to fault injection attacks was identified in wolfSSL’s ECC and Ed25519 signature verification operations. Fault injection is a sophisticated physical attack technique […]
