Decrypt manually not working in 3.0

[sauloseytiyamade]

I tried to use this solution to decrypt passwords, but has two problems:

1 - The function "cryption" now requires 4 arguments (before was 3). This can solve send blank in the last argument.

2 - Using the function "cryption" with passwords of the field "pw" of the table "teampass_items", and key of the file "teampass-secret.txt" the return is " an attack! either the wrong key was loaded, or the ciphertext has changed since it was created either corrupted in the database or intentionally modified by someone trying to carry out an attack." Have any other functions to execute before use cryption function?
