security.cfg has access to credential information.
We use AES-128 encryption method for security.cfg when "encrypt_user_info=yes" is used.
PBKDF2 hashing is used with "psv2_password=yes".
With psv2_password=yes, the password will have $PSV2$ prefixed. With encrypt_user_info=yes, the user content in security.cfg will be encrypted instead of plain text
