first thing is encrypt/decrypt if you input e it will encrypt otherwise it will decrypt next is the text just input what you want to encrypt/decrypt next 3 are the keys they have to be numbers (the bigger the better) they will be used to encrypt or decrypt the text
this cipher is nearly impossible to break it uses a pseudorandom number generated off of key1 key2 and key3 to apply a one time pad vigenére cipher to the text if the numbers were truly random then this cipher would be completely impossible to break but also you would need to input like a hundred key numbers, or it would be impossible to decrypt so you'd basically throw away the valuable information also to prove how hard to break this is 6l9z7rpaseexzrjfckdcjy0gxytdjkx13qn5ffzy5fl0
