To be honest - WRITE the passwords down somewhere safe.
OR use a set of passwords and only that set so you just have to try the
one at a time.
I use about a dozen passwords. If I need to create one that is not part
of my set of passwords, I write it down on a card and stick it in a
"safe place". That way if I do not remember what it is, I just pull out
the "cards" and find the document name and read the password written
there. I know a lot of businesses that use a locked desk drawer to hold
things like door access codes and passwords.

The Crypto++ library contains routines for encrypting/decrypting
blowfish, AES-256, and other algorithms for ciphers.
In 2001, four or five firms, worldwide, offered commercial OOo password
One of the firms frankly admitted that they used brute force. The setup
fee paid for the computers used for the "attack". The monthly fee
covered the utility bills that the "attack" generated. FWIW, this firm
now appears to be out of business.
http://openoffice-password-recovery.en.softonic.com/ offers a tool that
« OpenOffice Password Recovery is a software program to restore any
forgotten passwords from any document created with Open Office. This
tool supports all Open Office applications including OpenOffice Calc,
Impress, Math, Writer and Draw.
OpenOffice Password Recovery also features protection removal so you can
get rid of the read-only restriction used for protection with some files. »
http://openoffice-password-recovery.sharewarejunction.com/ offers an OOo
extension for US$79.00 that allegedly recovers passwords from OOo
Those tools might work, but I have my doubts. Whilst there are known
attacks that result in determining the password faster than using brute
force, those attacks require at least a century to complete, using
Beowulf Clusters that are currently commercially available.
