ERROR_IPSEC_IKE_INVALID_AUTH_ALG - 13874 (0x3632)

Introduction

This article provides a detailed explanation of the ERROR_IPSEC_IKE_INVALID_AUTH_ALG error code in Windows. This error is specific to the Internet Protocol Security (IPsec) and Internet Key Exchange (IKE) subsystems.

Technical Meaning

The ERROR_IPSEC_IKE_INVALID_AUTH_ALG error indicates that an invalid authentication algorithm was specified during IPsec or IKE operations. This can occur when a security protocol or policy is configured with an unsupported or unrecognized authentication method.

Error Details

This error code is returned by the Windows operating system to indicate that the specified authentication algorithm is not valid for the current context. The error typically occurs during the establishment of an IPsec Security Association (SA) or during IKE negotiations.

Usage Context

The ERROR_IPSEC_IKE_INVALID_AUTH_ALG error can be encountered in various scenarios, such as:

• Configuring IPsec policies with unsupported authentication methods.
• Mismatch between expected and actual authentication algorithms.
• Incorrectly specified security protocols that do not support the chosen authentication method.

Developer Interpretation

Developers should interpret this error code as an indication that a configuration issue exists. The application or system attempting to establish an IPsec connection must ensure that all security parameters, including the authentication algorithm, are correctly configured and supported by both ends of the communication.
