newwpcrack.c
C program to break the WordPerfect 5.1
encryption. It was discussed in Section 3.5.2.
wph.c

in the headers of WordPerfect files; it is invoked
as follows:
wph file1 file2
...
vigenere directory:
vigenere.c
This C program executes a Vigenere cipher of a
data stream (XORing with a periodically repeated
password). It is invoked on the command line:
vigenere keyword
<
plaintext
>
ciphertext
Repeated use turns the ciphertext back into the
plaintext. The program is intended only to create
ciphertexts for cryptanalysis.
vigcrack.c
For cryptanalysis of Vigenere-encrypted files. Its
operation is discussed in the source code. The
program was discussed in Section 3.6.3.
distr.c
Helper program for
vigcrack.c
; see there.
vigc crk.c
For cryptanalysis of Vigenere-encrypted
compressed files; see Section 3.6.4. Its invocation
is explained in the source code.

use other images in the X11 pixmap format, but
you have to edit the dimensions in
