When you add string.uppercase it messes with the decryption process occasionally.

[@romeo9015]

One way to make this more secure is to replace each character with a random number of characters. Then input more random strings of characters in between it. Keep track of what all these random string are equal to and implement a way of storing it separately from the message (another file works fine for testing). This will mean every message will have a different key, just like in the video. The method I described SHOULD prevent most simple cracking algorithms from accessing your data. You could further encrypt your keys with a separate, private algorithm if you’d like more security. There are also ways to encrypt the actual syntax in your algorithm if you need even more security (I forgot what this is called). If you need security for business or just doing wanna risk using your own, just use existing methods. It’s just more reliable.

I made a substitution cipher....Then, I got carried away and now it is a multistaged cipher but the shift value is randomized and contained but in its own cipher in the output. So, one input can result in over 50 different outputs, yet they all decipher to that input. Edit: I also made it random if the cipher itself is then ciphered again before being outputed.

one problem with this program is that so it generates random key every time you run it and if i close the program and reopen it i cannot decrypt the text, to solve this you could save key with someone indicator like e-; and then ask user for this indicator and then check if this key exist in the file

[@vadimkondratiev7214]

a question from a noob. If the encryption is random every time, how can it be used to encrypt and decrypt the messages on a constant basis?

[@Wenyi_Statistics]

please use goole translator to translate Chinese into English. 因为randomruffle()在整个程序的最外层，先执行random，生成了一个暗号，再执行加密解密。这个暗号在程序本次执行过程中是不变的，但是在每次点击三角，也就是新的一次执行全部程序的时候，暗号会出现变化。你说的情况当randomshuffle()在加密和解密两段代码的内部时会出现。

[@talaramadan1895]

if you still have the program running without ending and starting again, it would have the same key. but here when he re starts the program it generates a new key. so a way to overcome this is by saving the key in a variable after its been randomly generated for the first time. hope this helps!
