Summary of Changes

Hello @dmihalcik-virtru, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

I've added a new command-line option to the createNanoTDF command, allowing users to specify how the policy is embedded within the NanoTDF, either as plaintext or encrypted. This enhancement provides more control over the policy's visibility directly from the command line.

Highlights

• New policy-type option: Introduced a --policy-type command-line option for the createNanoTDF command, enabling users to choose between plaintext and encrypted policy embedding.
• Policy handling logic: Implemented logic to process the --policy-type argument, mapping plaintext to EMBEDDED_POLICY_PLAIN_TEXT and encrypted (or default) to EMBEDDED_POLICY_ENCRYPTED.

Code Review

This pull request adds a --policy-type command-line option to the encryptnano command, allowing users to specify whether the policy in a NanoTDF should be embedded as plaintext or encrypted. My review includes a suggestion to improve the robustness and readability of the new option handling logic by making it case-insensitive and using a more modern Java construct.
