/EFF name
(Optional; meaningful only when the value of V is 4; PDF 1.6) The name of the crypt filter that shall be used when encrypting embedded file streams that do not have their own crypt filter specifier; it shall correspond to a key in the CF dictionary or a standard crypt filter name specified in Table 26. This entry shall be provided by the security handler. Conforming writers shall respect this value when encrypting embedded files, except for embedded file streams that have their own crypt filter specifier. If this entry is not present, and the embedded file stream does not contain a crypt filter specifier, the stream shall be encrypted using the default stream crypt filter specified by StmF.
