I have used an older version of Stealth to encrypt some files. When decrypting them, some of the files did not decrypt and the file names remained as they were when encrypted (example 938473922.487). Now, when trying to decrypt them again, Stealth does not recognize them as encrypted files, meaning they are listed in the list of unencrypted files. I have used setting to Beginner, so no corruption should have been done if wrong password was used.
