simpleCrypt

A super simple encrypter and decrypter for plain text for macOS (10.10+)

This is just a basic idea in code form. The "encryption" (and I use that word loosely) process goes something like this:

• User inputs text and codeword
• codeword is made into an integer using unicode html codes
• text is translated letter for letter into their unicode codes
• each unicode letter code is multiplied by the codeword int
• since all the letters in the inputed text are all huge numbers, the largest product is found
• all the other numbers have 0's added to them for padding, I.E all the "encrypted" letters have the same character count
• the consistent character count is added to the front of the result string
• an integer saying how many digits the consistent character count is is added to the front
• the final string of numbers is produced
• that final string of numbers is converted into letters and numbers where possible using a custom 0-51 int to char system
• the final, shortened, string is displayed to user

Reading that made no sense to me and probably didn't make sense to you but that's fine

The "decryption" process goes like this:

• User inputs text and codeword
• codeword is made into an integer using html codes
• the text is divided into the encrypted letters using the consistent character count
• the letters are divided by the codeword integer to get the unicode html code
• the unicode html codes are made back into letters
• all the letters are added to make a string
• the decrypted string is returned to the user

Issues

There are a lot of issues with this software, and it'll probably crash frequently This is just the first version of a project that took 2 days to make so it's not a big deal

• Sometimes the last letters of the decrypted text are wrong [don't really know why]
• Sometimes encrypted text can be decrypted with several different codewords [will fix in next version]
• If there's an error saving the output as a txt file you won't know [will add an alert in next version]
• No async loading/loading indicator; encrypting/decrypting lots of text will lock UI [will fix in next version]
• Very little (if not none) of the code has notes [will add if requested]
