normally over 8 letters with special chars is impossible to crack, using brutal force needs at least several hundred years..., bad idea to try :-(.but it may take 30 mins to find the passwd precedure call and than crack it.
don't try to find password, try to make the program not to check the password, you know what i mean... -redspider(忙啥！歇着吧！); 2003-6-9 {181} (#1231870@0)

高人高人！感激感激！多多感谢指明了道路。可惜，偶不懂怎么搞。有这样的软件么？估计没有。能学会么？教你比把它整出来费80倍的劲。能帮忙么？如果有时间的话。：（ anyway, 万一高人哪天有空，能否帮忙crack一下？我的email:palate@rogers.com

不是那么简单的，我以前试过，人家可能故意在里面绕！ -m30(m30); 2003-6-9 (#1231956@0)

谢谢！偶正是在用这个破解版。这个“剃掉”是否指decrypt this document?如果是的话，这个decryption让偶输入密码。如果不是的话，能否指点一下，是哪个功能？找了半天没找着这个剃刀功能阿 :)

这个decryption的功能好像是在知道user password的情况下，彻底清除所有的encryption.但我就是不知道upw才着急的。请明示。谢谢！ -siebel(阿丽梦啊我来离萨); 2003-6-9 {156} (#1231986@0)
找到官方说法了：....However, such decryption possible only if “user” password (see below) is not set or known.找到官方说法了：Fortunately, there is no need to recover that password at all: instead, we can remove it (decrypt the file), so the resulting document will not have any restrictions. That’s exactly what APDFPRP does. However, such decryption possible only if “user” password (see below) is not set or known. -siebel(阿丽梦啊我来离萨); 2003-6-9 {310} (#1231993@0)
