Keith,
I was reconsidering your problem password.
It seems to me that since you desgined
your password to resist attacks,
you should design specialized dictionaries
in reverse. If, for instance, I was
going to create a dictionary to attack
a completely unknown, but long, password,
I would include certain characters to save
time: ETSLN and _!, for instance. You, however,
might want to include ZQJ and { | and the like.
If your password is 12 characters long
and you happen you to remember the first
four five characters, you could write your
cracker so that the first four or five
characters are constant, likewise for
constant characers whose position you
know.
I'd also check my other "crackable"
passwords. Might you have used the same
or similar password for stuff like pkzip,
screensavers, word docs?
If these sorts of dictionaries fail,
you might want to build a dictionary
from the entire contents of your hard drive.
Typically, when attacking a Windows
encryption program you need only build
a dictionary of printable ASCII characters.
I believe you've narrowed down the list
even further.
Good luck. I'm going to pour myself
a Vodka now.
Joe

Come on, guys, Shannon covered all this in his original paper.
There is approximately one bit of information per character in
normal English plaintext. => about 100 bits in the 97-character
message, under the reasonable assumption that the ciphertext and
plaintext have the same size.

sci.crypt Different methods of data en/decryption.
sci.crypt.research Cryptography, cryptanalysis, and related issues.
talk.politics.crypto The relation between cryptography and government.
The Cryptography FAQ is posted to sci.crypt and talk.politics.crypto
every three weeks. You should read it before posting to either group.
A common myth is that sci.crypt is USENET's catch-all crypto newsgroup.
It is not. It is reserved for discussion of the _science_ of cryptology,
including cryptography, cryptanalysis, and related topics such as
one-way hash functions.
Use talk.politics.crypto for the _politics_ of cryptography, including
Clipper, Digital Telephony, NSA, RSADSI, the distribution of RC4, and
export controls.
What if you want to post an article which is neither pure science nor
pure politics? Go for talk.politics.crypto. Political discussions are
naturally free-ranging, and can easily include scientific articles. But
sci.crypt is much more limited: it has no room for politics.
It's appropriate to post (or at least cross-post) Clipper discussions to
alt.privacy.clipper, which should become talk.politics.crypto.clipper at
some point.
There are now several PGP newsgroups. Try comp.security.pgp.resources if
you want to find PGP, c.s.pgp.tech if you want to set it up and use it,
and c.s.pgp.discuss for other PGP-related questions.
Questions about microfilm and smuggling and other non-cryptographic
``spy stuff'' don't belong in sci.crypt. Try alt.security.
Other relevant newsgroups: misc.legal.computing, comp.org.eff.talk,
comp.org.cpsr.talk, alt.politics.org.nsa, comp.patents, sci.math,
comp.compression, comp.security.misc.

This article appeared in the May 14, 1999 issue of Executive Intelligence
Review.
In case you have not heard, this is INCREDIBLE
http://www.larouchepub.com/diana_mi6_2620.html
The `MI6 factor' in the murder of Princess Diana
by Our Special Correspondent
Recently, EIR was one of several news organizations that received an
unsolicited e-mail transmission, identifying senior officials of MI6, the
British foreign intelligence service, including individuals who are accused
of having been involved in the Aug. 31, 1997 deaths of Princess Diana, Dodi
Fayed, and Henri Paul. The three were killed in a car crash in Paris, that,
to this day, remains one of the great unsolved mysteries of the 20th century.
More than 21 months after the crash, the official French
investigation, headed by Judge Herv� Stephan, is still under way, and some
of the most disturbing questions about the fatal crash remain unanswered,
including the most basic question: Was it an assassination?
EIR has been well-known for our exhaustive coverage of the death of
Princess Diana, identifying otherwise unpublished leads, and pointing to
the involvement of British and other intelligence agencies, in the run-up
to the crash, and in the effort to cover up the evidence that Princess
Diana and Dodi Fayed were the targets of a murder plot.
Some of the information provided in the e-mail posting has been
independently verified by EIR. Indeed, three MI6 officials, identified as
having been intimately involved in the events leading up to the fatal
crash, and the ensuing cover-up, have been previously identified by EIR as
suspected culprits, acting on behalf of the House of Windsor, under the
personal orders of Prince Philip.
In late 1997, EIR published exclusive photographs showing that a team of at
least seven men were surveilling the Ritz Hotel on the evening of Aug. 30,
1997--during the final hours before the crash in the Place d'Alma tunnel.
As this issue of EIR goes to press, a French court is in the process of
deciding whether Judge Stephan will be ordered to pursue further leads on
the crash provided by Mohamed Al Fayed, the father of Dodi Fayed, who has
made numerous public statements to the effect that he believes that the
crash was not an accident. Al Fayed is a civil party to the case, and, as
such, is entitled, under French law, to present new leads and evidence for
consideration by the chief investigator before the final report is released.
In the interest of furthering the investigation into the Paris crash, we
publish the text of the anonymous document below. We cannot, at this time,
independently authenticate many of the details provided. However, we pass
the document along as "raw" material. As we pursue the leads contained in
the document, we will keep our readers informed. Here is the e-mail text
(the names section contains the year and city to which the alleged agents
were posted):
The e-mail posting
Professor Pritchard of Gonville and Cauis College Cambridge is the leading
recruiter for MI6 agents. He identifies and recruits the most intellectual
geniuses for MI6.
The following three people are members of MI6, an organisation which forms
this supposed great country's intelligence service. It manipulates the
ordinary people of this country who are unaware of its illegal activities.
Sir David Spedding--Head of MI6--was ordered to organise the murder of
Diana, Princess of Wales and her friend Dodi Al Fayed.
Richard David Spearman--Chief of staff for Sir David Spedding. He was given
an assignment and moved to Paris two weeks prior to the murder of Diana,
Princess of Wales and Dodi Al Fayed.
Nicholas John Andrew Langman--Principal assistant to Richard Spearman. He
was also involved with Spedding in the murder.
Richard Billing Dearlove--the incoming Head of MI6 in September 1999--was
in Paris two weeks before the Aug. 31, 1997 crash.
The attached list identifies the unprincipled and unscrupulous individuals
involved with MI6 worldwide. The list was produced by an honest man who has
since left MI6 because he felt that the behaviour of that organisation was
unacceptable in a civilised society. They are accountable to nobody for
their law breaking activities. They are subordinated to the elite people of
this country, for example the Royal household and the establishment.
The whole world should be aware of these individuals and their
capabilities. British citizens need to know that these people are supported
by those ruling this country. This "Al Capone" style organisation has
removed the human rights of ordinary people, not only in this country but
worldwide.

I recommend against making the deck smaller or simplifying the
algorithm.
Historically, these ciphers have been slow. There is a Soviet
pen-and-paper cipher described in Kahn on Codes. It takes a few hours
to encrypt or decrypt a message.
