ERROR_IPSEC_IKE_PROCESS_ERR_HASH
ERROR_IPSEC_IKE_PROCESS_ERR_HASH means a hash payload in the IKE exchange could not be processed. It may be malformed, incompatible with the negotiated algorithm, or inconsistent with the negotiated message data.
Distinguish payload parsing from cryptographic verification by checking adjacent IKE errors and the negotiated algorithm. The first malformed or inconsistent message is more informative than later retries that rebuild negotiation state.
What to check
- Compare the negotiated hash/integrity algorithms and make sure both peers support them.
- Look for companion invalid-hash or invalid-hash-algorithm errors.
- Capture the exchange to isolate whether the peer or an intermediary generated the invalid payload.
