TPM aka Trusted Platform Modules

[jason0]

Hello,

According to the wikipedia article (insert grain of salt), the tpm not only has the ability to offload certain cryptographic functions, but also do things like be a hardware-based random number generator, store keys, etc.

1. How does this compare to the soekris crypto-accelerator (Just a co-processor?)
2. would it be useful (and can pfsense use it) for vpns, etc? (a driver like hifn for the crypto-framework?)

Thanks!

FreeBSD has a tpm(4) driver but it only mentions storing cryptographic keys as far as I can see, nothing about RNGs
