DiceWare was developed by Arnold G. Reinhold in 1995 as “a better way to create a strong, yet easy to remember passphrase for use with encryption and security programs.” This form of passphrase generation allows for random pass-phrases that not related to the user in any way. The implementation is a Microsoft Excel (xls) or Oracle Open Office (ods) spread sheet using Visual Basic for Applications and Open Office Basic respectively.
Documentation is included in the file itself. To select a different pass-phrase, change any empty cell. You can change the same cell over and over again to change the pass-phrase. It is recommended that the spread sheet file be saved read only.
Though usable, this application does not use the latest DiceWare word list, and could be improved with the addition of different language versions. Other language versions of the list are available on the DiceWare site.
