Use Cases

Intra-file Variable Security Regions (VSR)

[StrongBox UC flag: uc_secure_regions]

Communicating classified materials, grand jury testimony, national secrets, etc. require the highest level of discretion when handled, yet sensitive information like this often appears within a (much) larger amount of data that we care less about in context.

#!/bin/bash

# A little program to quickly stress test a server
# blitz <url> <# of requests> <method>
# <url> defaults to localhost
# <# of requests> defaults to 30
# <method> defaults to POST

# Probably a good idea to type method names with capital letters

// Takes an object and replaces the circular references (including deep circular references) with strings
var uncirc = function(obj, ident, seen)
{
    seen = seen || {};

    // Push the object identity (key) and object (value) onto the "seen" list
    seen[ident] = obj;

    // Returns the ident of a value or null if we have not yet seen it
    // Could have made this an anonymous function
