- Description:
- This package implements an algorithm for breaking the PkZip cipher that was
devised by Eli Biham and Paul Kocher.
This program applies a known plaintext attack to an encrypted file.
A known-plaintext-attack recovers a password using the encrypted file and
(part of) the unencrypted file.
Please note that cryptographers use the word 'plaintext' for any kind of
unencrypted data - not necessarily readable ASCII text.
Before you ask why somebody may want to know the password when he already knows
the plaintext think of the following situations:
- Usually there's a large number of files in a ZIP-archive. Usually all these
files are encrypted using the same password. So if you know one of the files,
you can recover the password and decrypt the other files.
- You need to know only a part of the plaintext (at least 13 bytes). Many files
have commonly known headers, like DOS .EXE-files. Knowing a reasonably long
header you can recover the password and decrypt the entire file.

Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.
