Core engineering and protocols for PKCS#11 & OpenSSL 3.x Providers.
Enterprise applications communicate with cryptographic hardware through standardized software interfaces. TPMVault provides modern, thread-safe PKCS#11 modules and OpenSSL 3.x Providers (tpm2-provider) updated with support for FIPS 203 and FIPS 204 algorithm parameters.
When NGINX or an internal database service performs a post-quantum TLS handshake or decrypts an encrypted database volume, private key operations are offloaded directly to the TPMVault hardware. The raw private key bytes never enter host OS memory, completely shielding them from memory scrapers and root compromises.
