No. Cf. section 7.6.3.2 Standard Encryption Dictionary of ISO 32000-1:2008 on encryption dictionary entries for the standard security handler: > O string (Required) A 32-byte string, based on both the owner and user > passwords, that shall be used in computing the encryption key and in > determining whether a valid owner password was entered.

For more > information, see 7.6.3.4, "Password Algorithms." Both these values are required in that dictionary. Thus, both a user and an owner password value are required. For the user password the specification defines an explicit default value. And for the owner statement it says what I posted in my previous message in this thread.
