The algorithm gets the number associated with each char, then adds a random number to it and saves the numbers it added. I plan to make an Encrypter class later. Here is the entire project:

Encrypterclass later - I would suggest doing organizational tasks like that before implementing anything at all. You're not benefitting by coding everything then having to reorganize later, because you have to update half your code to handle the new architecture. It's especially a good idea to do that before posting to CodeReview :) \$\endgroup\$Randomwas usable for cryptography (it's not) - just the seed value, which would allow you to regenerate the sequence on-the-fly. 2) Normally when you do something like this, you restrict the random range to your input range (eg, all letters, numbers, etc), add and then apply mod (%- or a couple of other options, and this usually operates on the byte level, too). For one thing, it prevents single-possibility results; if your current program outputs0, there's only one possible input. \$\endgroup\$
