TPM_20_E_BINDING
TPM_20_E_BINDING maps to TPM_RC_BINDING. Before an object is used, the TPM verifies that its public and sensitive portions describe the same cryptographic object. A failure means the two portions are not properly linked, not merely that a parent handle is unavailable.
Where it commonly matters
- Inspect serialized public and private blobs as a matched pair; do not combine files from different creation or import runs.
- For RSA and ECC objects, verify that public components correspond to the private material that was loaded.
- Use the original parent and import parameters when reconstructing or moving an object between workflows.
