Remarks:

The password strings in PDF are padded or truncated to exactly 32 bytes. If the password string is more than 32 bytes long, used only its first 32 bytes; if it is less than 32 bytes long, it padded by appending the required number of additional bytes from the beginning of the following padding string: <28 BF 4E 5E 4E 75 8A 41 64 00 4E 56 FF FA 01 08 2E 2E 00 B6 D0 68 3E 80 2F 0C A9 FE 64 53 69 7A >

Not all combinations of encryptMethod, keyLength, version and revision are valid. An error is not returned for invalid combinations. Instead, a different valid combination is used to secure the PDF and a warning is added to the warning list. The following combinations are valid:
