TPM_20_E_INTEGRITY

TPM_20_E_INTEGRITY maps to TPM_RC_INTEGRITY. It indicates that protected data failed an integrity check. For example, the TPM 2.0 specification requires TPM_RC_INTEGRITY when a saved context passed to TPM2_ContextLoad has an invalid integrity HMAC.

Safe handling

Treat the serialized object or context as invalid; do not attempt to repair, edit, or reuse it.
Check that the blob came from the same TPM and that no backup, conversion, or transport layer changed its bytes.
Re-create the context or object through the documented workflow rather than suppressing the integrity result.
