--- Comment #8 from [email protected] --- * LO limits password *entry* to 15 characters when *saving* as (at least) DOCX or XLSX. There is no visual indicator that further characters are being ignored, other than that no more asterisks appear. * LO does *not* limit password entry length when *decrypting* DOCX/XLSX files. * Office 2013 (at least) doesn't limit passwords to 15 characters. Saving with a 20-character password in Office 2013, it is successfully decrypted with the same 20 characters using LO. Decryption fails when only entering the first 15 characters, so LO does seem to use the full length for decryption. * It seems there was a limit in *earlier* versions of Office to passwords of 15 characters or fewer, for example: http://support.microsoft.com/kb/KbView/291457 At least two things are needed here: * If LO is limiting password entry on OOXML to 15 characters, it needs to actively alert the user. Otherwise the user may enter a long password, not notice that it has been truncated, and be unable to open it with the password they *typed*. This is exactly what happened to me, and I was only able to regain access by experimenting to find the cause. * Compatibility of >15-character-passworded OOXML documents with earlier OOXML-capable versions of Office (2007, 2010). If 2007 and 2010 are long-password-capable, the artificial limit on OOXML password creation length needs to be removed from LO (assuming it is just a deliberate truncation on entry). -- You are receiving this mail because: You are the assignee for the bug.
