Thanks for your message.
Perhaps you dont need such a powerful signature?
Can you help with my problem please?

> Date:My source forge project is:
To use source codes from Bruce
Schneier's book "Applied Cryptography"
to compile and run in C++, but there
are problems with parsers and binaries.
Anyone interested?
Also I have a problem with this prog:
/* This program enciphers files using
one of Vigenere, Beauford or
   Variant Beauford ciphers. Note
inverses means this code also
   decrypts - eg encipherment by
Vigenere can be deciphered by
   enciphering with Variant Beauford
with the same key. Similarly,
   Beauford is its own inverse.
   Input via file or keyboard is of the
following format:
 the message in free format, of
any desired length
   Output will be of the form:
 theen ciphe redme ssage
   The cipher type is given by the
single letter V (or v) for Vigenere,
   B (or b) for Beauford and A (or a)
for Variant Beauford. Should a
   different letter be used, a message
will be printed to the screen and
   Vigenere used.
   Currently the maximum allowed key is
10 characters. Excess is discarded
   with a warning message sent to the
screen. MAXKEYLENGTH can be changed
   for longer or shorter limits. The
key can be *any* ASCII characters, not
   just alphabetics.
   Note upper and lower case plaintext
are enciphered by converting all to
   lower case first, with the output
solely lower case. Non-alphabetics are
   discarded, however relatively minor
adjustments could be made to allow
   longer alphabets.
   The output is given in the
traditional 5 letter chunks, but
   can be changed to suit personal
taste. Similarly, 80 character lines
   assumed, but other lengths can be
set with LINELENGTH.
   Two versions of main are given: one
for input from the keyboard or from
   file redirection, the other for
input from a file named on the command
   line. Just uncomment which you wish
to use. Note both send output to the
   screen by default, and allow output
redirection to a file (eg ... >
   If you wish to specify the output
file, the modification is minor.
   An example for program verification:
 An ambassador is an Honest man
sent to Lie and Intrigue abroad for
 the benefit of his Country
   produces output:
 oebuu ojtiw cijat bypvx gknig
gvobm ccjmt bujvm fzhcx osswt rwpzm
 vvcmg swjbh tyjav clobk m
   Note no padding at the end to hide
the message length: this is easily
   For instance, the final message
letter can be enciphered repeatedly
   with progression through the key to
hide the effect) until a block is full.

When I build and run this prog. i get
the message"Failed to launch there are
no binaries"
Please help.
