Encryption program. Parse a string using Newton's encryption, based on a letter he wrote to Leibniz explaining fluxion, to encrypt it.

Newtons-Cipher

Description

On October 24th 1676, Newton wrote a letter to Leibniz in Latin explaining fluxion, but the letter was actually concealed in code because he was suspicious of Leibniz. The program will prompt and take in a string, transverses and encipher it with Newton's cipher. For example: I am Batman will translate to 3abimmn.

How does the cipher work?

Encryption program. Parse a string using Newton's encryption, based on a letter he wrote to Leibniz explaining fluxion, to encrypt it.

• The string is re-arranged into alphabetical order
• Counts the frequency of a letter and represent it with a number, if the frequency is less than 3 then it is printed twice
• (For e.g. I am Batman, there are 3 a's so 3a, 2 m's so mm.

Task lists

• Optimize 🎉
• Take in a whole file of text (paragraphs & sentences) instead of inputing from console
• #1
• Decipher the string after encrypting it

newtons-cipher's Issues

Known issues

• Script also traverses through 'spaces', For example: I really like Banana will turn into 3 4abeeiik3lnnry. 3 is an unwanted output, removing space will add to count a and n for some reason?
• Memory allocation
• Limited length to only 50 characters (can bump up or down but ideally it should get the user's inputted text length without having to go through type coercion(?) or something) <-- No idea how to fix, tried everything
