String obtained from file decryption not complete

String obtained from file decryption not complete

I have made something that can successfully write an encrypted string to a
file, although unfortunately when the file is decrypted, the string is
incomplete and incorrectly formed.
The string I write to the file is:
"This should be written to the file and read perfectly. There should be no
limit to the length of a string."
The string I recieve from the file is:
"g.is should be written to the file and read perfectly. There should be no
limit to the length of a strin"
Note the "g." at the end of "string" is instead at the start, and the "th"
is missing from "this".
The methods I use to encrypt/decrypt files can be found below. I will be
very grateful for any help.
