ERROR_IPSEC_IKE_INVALID_GROUP - 13865 (0x3629)

Technical Meaning

The error code ERROR_IPSEC_IKE_INVALID_GROUP (13865, 0x3629) is returned when an invalid Diffie-Hellman group is detected during IPsec/IKE operations. This indicates that the specified Diffie-Hellman group parameter does not meet the required criteria or is unsupported by the system.

Error Details

The Diffie-Hellman key exchange protocol is a fundamental component of IPsec and IKE (Internet Key Exchange) for establishing secure communication channels. The validity of the Diffie-Hellman group is critical to ensure cryptographic security. An invalid group can lead to security vulnerabilities or operational failures.

Usage Context

This error typically occurs during the negotiation phase of an IPsec/IKE session, where parameters such as the Diffie-Hellman group are exchanged and validated. The specific context in which this error is generated depends on the implementation details of the IPsec/IKE stack being used.

Developer Interpretation

Developers should interpret this error code to indicate that a parameter passed during an IPsec/IKE operation was invalid, specifically related to the Diffie-Hellman group. This could be due to incorrect configuration, unsupported parameters, or misconfiguration of security policies.

Related Errors

• ERROR_IPSEC_IKE_INVALID_POLICY (13864, 0x3628): Indicates an invalid IPsec policy.
• ERROR_IPSEC_IKE_NO_PRIVATE_KEY (13875, 0x364B): Indicates that a required private key is missing.

FAQ

Q: What does ERROR_IPSEC_IKE_INVALID_GROUP mean?

A: It indicates an invalid Diffie-Hellman group in IPsec/IKE operations.

Q: How can I resolve this error?

A: Ensure the correct and supported Diffie-Hellman group is configured for your IPsec/IKE setup.

Summary

ERROR_IPSEC_IKE_INVALID_GROUP (13865, 0x3629) signifies an issue with a specified Diffie-Hellman group during IPsec/IKE operations. Developers should ensure that all parameters are correctly configured and supported by the system to avoid this error.
