ERROR_IPSEC_IKE_INVALID_HASH - 13870 (0x362E)

Hash verification failed.

Updated: Feb 21, 2026

Technical Background

The ERROR_IPSEC_IKE_INVALID_HASH error indicates a failure in the validation of cryptographic hash values during the Internet Key Exchange (IKE) protocol process. This error is specific to the IPsec security framework, which is used for secure communication over IP networks.

Error Details

  • Error Name: ERROR_IPSEC_IKE_INVALID_HASH
  • Numeric Code: 13870
  • Hex Code: 0x362E
  • Short Description: Hash verification failed.

This error suggests that a hash value, which is used for integrity checks, did not match the expected value during an IKE negotiation or IPsec policy application. The hash values are typically generated by cryptographic algorithms to ensure data integrity and authenticity.

Common Causes

  1. Invalid Parameter Values: Incorrect parameters passed during the IKE negotiation process may lead to a mismatch in hash values.
  2. Incorrect Object Type: The operation being performed might be applied to an object that is not compatible with IPsec, leading to unexpected behavior.
  3. Corrupted Data: If data involved in the hash calculation is corrupted or tampered with, it can result in a failed verification.

Real-World Context

In practical scenarios, this error may occur when attempting to establish a secure connection using IPsec, particularly during phase 1 (IKE) negotiations. It could also arise if there are issues with the configuration of security policies or keys involved in the process.

Is This Error Critical?

The criticality of this error depends on the context. In some cases, it might indicate a minor issue that can be resolved by reconfiguring settings. However, in other scenarios, it could point to more serious problems such as key compromise or data corruption.

How to Diagnose

  1. Review Operation Context: Ensure that all operations are being performed within the correct context and that no unexpected changes have been made.
  2. Validate Parameters: Double-check all parameters used in the IKE negotiation process, including keys, certificates, and policy settings.
  3. Confirm Object Types: Verify that the objects involved (such as security policies or keys) are of the expected type and correctly configured.

How to Resolve

  1. Correct Parameter Usage: Ensure that all parameters are correctly specified and match the requirements for IPsec operations.
  2. Adjust Operation Context: If the operation context is incorrect, adjust it to ensure compatibility with IPsec protocols.
  3. Restore Data: If data corruption is suspected, restore from a known good backup or reinitialize the affected components.

Developer Notes

Developers should be aware that this error can occur due to various factors and should implement robust validation mechanisms for all parameters involved in IKE negotiations and IPsec policy application.

Related Errors

  • ERROR_IPSEC_IKE_NEGOTIATION_FAILED (13869): Indicates a failure during the IKE negotiation process.
  • ERROR_IPSEC_POLICY_NOT_FOUND (13872): Suggests that the required security policy is missing or incorrectly configured.

FAQ

Q: What does ERROR_IPSEC_IKE_INVALID_HASH mean?

A: It indicates a failure in hash verification during an IKE negotiation, suggesting potential issues with data integrity or configuration.

Q: How can I prevent this error from occurring?

A: Ensure that all parameters and objects involved in IPsec operations are correctly configured and validated before use.

Summary

The ERROR_IPSEC_IKE_INVALID_HASH error is a specific indication of a failure in hash verification during the IKE protocol process. It requires careful review of configuration settings, parameter values, and data integrity to resolve effectively. Developers should implement robust validation mechanisms to mitigate this issue.
