Two PowerShell scripts/utilities for creating 1. combinations and 2. hash strings using CRC-16 or/and CRC-32

I wish to hire a developer who can create two PowerShell scripts along with two utilities FIRST SCRIPT/UTILITY It will hash a string determined by me through a variable (e.g. - String). The script/utility will return the hash of the string using the algorithms CRC-16 or CRC-32. The algorithm will be determined by me inside the script I want to be able to determine the original string (plain text) and get the hashed string. To practically understand what I mean, visit the page below. Type a word in the first text field and get the result in the second. [login to view URL] HASH SECURITY IS NOT MY CONCERN. That is why I choose CRC hashing instead of other more secure hashing algorithms. My concern is to get a hash which will be shorter than the original text. Example: Original text = This is my text Hashed text = e489ba80 SECOND SCRIPT/UTILITY It will create all possible combinations of the elements that I will determine (uppercase/lowercase letters, numbers, symbols etc). I also wish to determine the number of elements in each combination (r). Example: a7fgh68r (8 elements in each combination) x756ythfgjhd (12 elements in each combination) Multiple instances of each element ARE ALLOWED. Example: abca abcb aaac etc In other words, the script utility is free to do anything Because I will create millions of combinations (maybe 16 million), I would like to store them in more than one files, in order to be able to open them easily without overloading memory. For this reason I would like to determine: 1. The number of combinations stored in each file (e.g. -CombinationsInEachFile=20000). 2. The location where those files will be stored. The name of the files will automatically be created by the script/utility. Example: [login to view URL] [login to view URL] .........

PAYMENT I will not release any milestone until I will test the developer's work and make sure is working as expected (at least on my PC)!
