Re: Perl and RC4: Understanding Extremely Compact Script

In attempting to better understand the underlying mechanisms at work with the
RC4 encryption algorithm and its associated weaknesses, I began writing a
perl script to replicate it (for educational purposes only). Just At the
point where I thought I had it figured out, I came across an example in PERL
5 that blew my mind. Although it is absolutely accurate, is extremely
precisely written and compact, making it difficult to decipher (no pun
intended :). I could use some help breaking this script down and
understanding what's happening with each step...more like one big step.
RTFMing hasn't helped much, as I'm familiar with all of the syntax used, but
the nesting of variable, arrays, and regular expressions makes it tough to
understand what is happening and when.
Anyone care to help decipher what's going on, command by command here? TIA.
Oh, and thanks to John Allen ([EMAIL PROTECTED]) for the very nicely
written Perl 5 script:

Re: Editor - finding lines

Find the first one and then hit next for the next one etc. That, IMO is the best feature of Crimson Editor... you can highlight something with the mouse, hit F3 and it takes you to the next instance of it, hit shiftF3 and it takes you to the previous one. in vim you position the cursor over a word, and hit '*' to jump to the next + highlite all matches. 'n'/'N' will move you to the next/previous match. I would like it even better though, sometimes I want to highlite several items in different colors, like keeping multiple active searches, each with a different highlite color. And for free, it's worth every penny ;-) vim, even freeer. one of my favorite vim features, is the ability to pipe a selected portion ( or all ) of the text through an external program, and have it replace by the output of this program. when manipulating some piece of information, I often prefix it with '__DATA__' and a little bit of perl, starting with 'while (DATA)', and then pipe the whole contents of my current window through perl, with '!Gperl' so I can easily experiment with the data while keeping it in my editor.
