TPM vs HSM, what’s the difference? Check out this blog post for more detailed. In a nutshell, TPMs are typically a dedicated chip included along side a main (host) processor and used for securing a single consumer electronics device. HSMs are external devices that can be used across multiple devices and systems, offering advanced cryptographic […]

We’re excited to share a new feature added to wolfTPM: a lightweight example for verifying TPM Endorsement Key (EK) Certificates without wolfCrypt. The new example, `verify_ek_cert`, retrieves and verifies the EK certificate stored in the TPM’s non-volatile memory. This supports TPMs like the Infineon SLB9672/SLB9673, STMicro ST33 series, and validates their RSA-signed EK certs using […]
