      Parameters:
      prefix - classpath prefix to scan (e.g. "META-INF/modules/uuids/")
      Returns:
      resource paths relative to the classpath root
      Throws:
      IOException - if classpath enumeration fails

    • getModulesUUIDs

      public static List<String> getModulesUUIDs() throws IOException
      Returns the sorted list of module UUIDs discovered under META-INF/modules/uuids/.
      Returns:
      module UUIDs (one per registered module)
      Throws:
      IOException - if classpath enumeration fails

    • getRKeys

      public static List<String> getRKeys() throws IOException
      Returns the sorted list of revocation-key identifiers discovered under META-INF/modules/rkeys/.
      Returns:
      revocation key identifiers
      Throws:
      IOException - if classpath enumeration fails

    • getSystemHash

      public static String getSystemHash() throws IOException, NoSuchAlgorithmException
      Returns the Base64-encoded SHA-256 hash of the concatenated module UUIDs, used as a per-installation fingerprint by license verification.
      Returns:
      Base64 SHA-256 hash, or empty string when no UUIDs are registered
      Throws:
      IOException - if classpath enumeration fails
      NoSuchAlgorithmException - if SHA-256 is unavailable
