Description Aron Budea 2017-06-26 01:41:21 UTC
Created attachment 134283 [details]
Password protected DOC

The attached document was created with Word 2013, and is protected with a password. Password is: 1234

Open document in Writer using the password, then save it.
Reopen document either in Writer or in Word.

=> Document is not protected with password anymore, and can be opened without one.

Observed using LO 5.4beta2 & / Windows 7.
In this kind of password protection is not yet supported for DOC files.

This is the commit that implemented import support:

committer	Caolán McNamara <caolanm@redhat.com>	2016-10-22 20:09:59 (GMT)

implement CryptoAPI RC4+SHA1 encryption scheme for doc import
Comment 2 Xisco Faulí 2017-06-26 11:11:42 UTC
The behaviour is somehow inconsistent.
If the file is saved with another name or in another folder, it's password protected after roundtrip. However, if it's saved using the same file, the protection is lost after roundtrip.

Comment 3 Marina Latini (SUSE) 2017-09-21 14:29:51 UTC
Could be a different bug but, when you try to open a password protected doc file generated by MS Office, LibreOffice opens it in read only mode without asking for the password.
