TPMAPI_E_FIPS_RNG_CHECK_FAILED
TPMAPI_E_FIPS_RNG_CHECK_FAILED is a Windows TPM API result. It indicates that generated random data failed the validation performed by the TPM API FIPS random-number check.
What to check for TPMAPI_E_FIPS_RNG_CHECK_FAILED
- Stop using the returned random data and preserve the error context for security diagnostics.
- Check TPM firmware, Windows updates, and any hardware-health events before retrying.
- Escalate repeated failures to the device or platform administrator because they can indicate a security-relevant fault.
Microsoft documentation for TPMAPI error codes
Diagnostic discriminator: Treat the generated random block itself as the discriminator: the TPM API produced data that failed the required FIPS RNG validation. Retrying unrelated command parameters does not address that condition.
