			No more; and by a sleep to say we end
			The heart-ache, and the thousand natural shocks
			That flesh is heir to, 'tis a consummation
			Devoutly to be wish'd. To die, to sleep;
			To sleep: perchance to dream: aye, there's the rub;
			For in that sleep of death what dreams may come,
			When we have shuffled off this mortal coil,
			Must give us pause: there's the respect
			That makes calamity of so long life;
			For who would bear the whips and scorns of time,
			The oppressor's wrong, the proud man's contumely,
			The pangs of despised love, the law's delay,
			The insolence of office, and the spurns
			That patient merit of the unworthy takes,
			When he himself might his quietus make
			With a bare bodkin? who would fardels bear,
			To grunt and sweat under a weary life,
			But that the dread of something after death,
			The undiscover'd country from whose bourn
			No traveler returns, puzzles the will,
			And makes us rather bear those ills we have
			Than fly to others that we know not of?
			Thus conscience does make cowards of us all,
			And thus the native hue of resolution
			Is sicklied o'er with the pale cast of thought,
			And enterprises of great pith and moment
			With this regard their currents turn awry
			And lose the name of action.";

[code34 248]

i dont think you can use paste / bin directly the sequence into forum to use it :( There is some extra char that certainly should be escape.

 

To do those kind of things, the cipher string should be export to hexa format. It certainly should work

das attorney what do you think about that, ready for another test :p

 

just add v 0.2 to github

 

i have a very strange behavior :( hexa convertion works, un/cipher seems to work too, but i dont have compatibility with RC4 online tools oO

[das attorney 857]

Looks good  :)

 

[code34 248]

That gives so many possibilities, I'm like a child in front of a Christmas tree :D

[code34 248]

i investigated about the compatibilities. It dont really understand where it comes from, but it seems that certains website doesnt use the same algorithme to generate the first key.

 

I use the original algorithm and add my own part (no more compat with external system), it s perhaps better but dont know until which point.

 

Anyway, i just release the version 0.4 (perhaps the last ?)

 

changelogs:

- i refactory factory name, now use cipher / uncipher methods to do the jobs :)

- export of ciphered data are in hexa format

- 2048bits key

[code34 248]

hi

 

Just release a hotfix  v0.5

 

- fix a major issue concerning stream generation

- fix the mod value

- tune hexa for command line tools

 

https://github.com/code34/oo_cipher.altis

 

all script / modules that used version 0.4 should be upgrade as soon as possible.

[code34 248]

hi Dudes :)

 

Just release a command line tool "LUCIPHER" compatible with OO_CIPHER

 

more informations at this place

 

[code34 248]

hi :)

 

As request by community member, i also released the RC34 procedural version on MIT licence.
