I tried to open a document that was encrypted but I am getting the error " invalid signature "..I know the password is correct because I encrypted it myself using (wapwolf from my dropbox). What is the problem? Can anyone help us?

The "invalid signature" error is an unfortunate error message. What it means is that the 'AES' header was not observed at the start of the file. It's a basic sanity check to ensure that the file format is known before attempting the decryption process. A better message would be "invalid AES file". I'll add that to the to-do list.
