Summary:

The changes in this GitHub Pull Request are focused on the AttestationFormat and AttestationErrorResponseType classes in the jans-fido2 project, which is likely a FIDO2 (Fast Identity Online) implementation. The key changes include the removal of the android-key and android-safetynet values from the AttestationFormat enum, as well as the removal of the ANDROID_KEY_ERROR and ANDROID_SAFETYNET_ERROR enum values from the AttestationErrorResponseType class.

From an application security perspective, these changes suggest that the project is no longer supporting the Android-specific FIDO2 attestation mechanisms, either due to security concerns, changes in platform requirements, or a strategic decision to focus on other attestation formats. While the remaining attestation formats still provide a good range of options for developers, the removal of the Android-specific features may impact the functionality or compatibility of the application, depending on its use cases and integrations.

It's important to thoroughly review the application's security requirements, use cases, and any potential impact on existing functionality to ensure that these changes do not introduce any unintended security vulnerabilities or regressions. Additionally, the reasons behind the removal of the Android-specific features should be carefully considered to understand the overall security and reliability implications for the FIDO2 implementation.
