wolfSSH Continues on the Post-Quantum Hybrid Key Exchange Journey

Go checkout the master branch of wolfSSH. Two new hybrid KEX methods have been added. Both are defined in draft-ietf-sshm-mlkem-hybrid-kex: mlkem768x25519-sha256 — ML-KEM-768 paired with X25519 mlkem1024nistp384-sha384 — ML-KEM-1024 paired with NIST P-384 This joins mlkem768nistp256-sha256 which has been there for a long time. Why hybrid The “harvest now, decrypt later” threat model means ciphertext […]

wolfCrypt FIPS 140-3 for WireGuard and Kernel Mode Applications

FIPS 140-3 Kernel Crypto: libwolfssl.ko delivers a FIPS 140-3 compliant cryptographic stack for the Linux kernel, using the same validated wolfCrypt implementations as the user-space library. wolfGuard: WolfGuard is a FIPS 140-3 implementation of WireGuard which replaces WireGuard’s non-FIPS algorithms with wolfCrypt’s FIPS based AES-GCM, ECDH, SHA-256 HMAC, and HASH-DRBG. WolfGuard-Go is the Go implementation […]
