Detect Underlying Value Changes in Masked Sensitive Configuration Fields

NetBrain's pre/post configuration comparison currently evaluates the masked or displayed value of sensitive fields rather than the underlying data, so a change to a hashed-out field appears identical across snapshots and is reported as no change. This same limitation affects configuration restoration and export, since a masked value cannot be meaningfully copied back to a device. This enhancement would allow comparison, restoration, and export processes to detect that the underlying value of a masked sensitive field has changed by comparing a hash or fingerprint of that value, while continuing to display the field as masked to the user. Customers would gain accurate change detection and reliable restoration behavior for sensitive fields without compromising the security benefit of masking.
