The empty password opens an EFOpen-only document as no password does, and the credentials of one opened without the key open no other. An embedded file may name its EFOpen filter in a /Crypt filter of its own, with no /EFF; handlers older than crypt filters (V1, V2) don't qualify (hayro-syntax patch 36 too). Saves without the key refuse what they would have to encrypt: a removed /Encrypt, or an edited or added embedded file. The password given after opening unlocks the embedded files, unless one read as stored has been edited.
