After I accept this, I can read the file.The behaviour is not limited to Mavericks or Word or Excel files. But when I open it I get a message that the file 'is locked for editing' as it is open on the other computer too.

Make sure the file is open by another user or on another device. Make sure the file is open by another user or on another device. 2 History of Microsoft Encryption passwordCheck if there is another user editing the same file. Unable to install Microsoft Office 2001 on Mac OS X. Office Word 2011 for Mac scrambles hyperlinks with different schemes. Office 2011 issue with emailing an attachment.

It is possible to set this type of password in all Microsoft Office applications. In Microsoft Excel passwords restrict modification of the workbook, a worksheet within it, or individual elements in the worksheet.The password that encrypts a document also restricts the user from opening the document. In Microsoft Word and in Microsoft PowerPoint passwords restrict modification of the entire document or presentation. To disable file locking, edit the soffice script and change the.Microsoft Office applications offer the use of two main groups of passwords that can be set to a document depending on whether they encrypt a password-protected document or not.Passwords that do not encrypt a password-protected document have different security level features for each of Microsoft Office applications as mentioned below. I will not tolerate file locking.

Choosing a non-standard Cryptographic Service Provider allows increasing the key length. This protection algorithm is also currently considered to be weak and presents no difficulties to hacking software.The default protection in Office XP and 2003 was not changed, but an opportunity to use a custom protection algorithm was added. In Excel and Word the key length was increased to 40 bits. Hacking software is now readily available to find a 16-bit key and decrypt the password-protected document instantly. To provide improved security, Microsoft has been consistently enhancing the Office encryption algorithm strength.History of Microsoft Encryption password In Excel and Word 95 and prior editions a weak protection algorithm is used that converts a password to a 16-bit key. Due to the encryption of a document protected by a password to open it, a hacker needs to decrypt the document to get access to its contents.

Office 2016 (Access, Excel, OneNote, PowerPoint, Project, and Word) uses 256-bit AES, the SHA-1 hash algorithm, and CBC ( Cipher Block Chaining) by default. With the help of the SHA-1 hash function, the password is stretched into a 128-bit key 50,000 times before opening the document as a result, the time required to crack it is vastly increased.Excel and Word 2010 still employ AES and a 128-bit key, but the number of SHA-1 conversions has doubled to 100,000 further increasing the time required to crack the password.Office 2013 (Access, Excel, OneNote, PowerPoint, Project, and Word)uses 128-bit AES, again with hash algorithm SHA-1 by default. At present there is no software that can break this encryption.

If the password can be determined through guesswork or social engineering, the underlying cipher is not important.
