Python Encryption - Unexpected Variable Return

I am currently having an issue of not being able to decrypt the text provided after encryption. It returns: Key: ﾝƚ!*!ﾞﾫø}Qd`Dﾫd!Þxͦ}ﾰﾐﾡ>'U Unpadded Text: Hel

Solution 1:

You are transferring your ciphertext and key as strings. You should make sure that the bytes that make up the ciphertext and keys stay intact. If you want to transport them using character strings, please use either hexadecimal encoding or base 64. Hexadecimals are easier to read and check for length, base 64 is more efficient.

Note that the ciphertext will contain bytes with any value, including ones that are ASCII control characters (< 0x20) which also contain termination characters such as 0x00.
