Post-Quantum Firmware TPM Is Here wolfTPM’s firmware TPM (fwTPM) is available with post-quantum cryptography support added through the TCG TPM 2.0 Library Specification v1.85. fwTPM is wolfSSL’s portable software TPM 2.0 implementation, built on wolfCrypt and intended for products that need a TPM 2.0 interface without a discrete TPM chip....Read more -
RSA-PSS Support for PKCS#7 SignedData in wolfSSL
PKCS#7, standardized as Cryptographic Message Syntax (CMS) in RFC 5652, is a common format for signing structured data. Signed firmware updates, signed configuration packages, and certificate-based authentication workflows all rely on PKCS#7 SignedData to ensure integrity and authenticity.wolfSSL now supports RSA-PSS (RSASSA-PSS) signatures in PKCS#7 SignedData, for both generation and...Read more -
TPM 2.0 Sealing Policies with wolfTPM: PCR Policies, Policy Authorize, and NV Storage for TPM 2.0 Secrets
Background: TPM 2.0 Sealing and PCR Policies TPM 2.0 sealing binds a secret to a set of Platform Configuration Register (PCR) values. The TPM will only release the secret when the current PCR state matches what was recorded at seal time. This is the foundation for measured boot, disk encryption...Read more -
