SubjectRe: [PATCH] KEYS: asym_tpm: Switch to get_random_bytes()
The TPM library specification states that the TPM must comply with NIST 
SP800-90 A.

shows that the TPMs get third party certification, Common Criteria EAL 4+.

While it's theoretically possible that an attacker could compromise
both the TPM vendors and the evaluation agencies, we do have EAL 4+
assurance against both 1 and 2.
