[REQUEST]Decrypting Codes ?

The thing is... Unless you can identify a key for the method of encryption with modern day tech you'll be (way) dead and gone before a single line is unencrypted. Practical decrypting is done by formulating an Algorithm based on data referred to as a key, basically a table of what you got after you encrypted characters or whatever ~
In a method of asymmetrical encryption which is used by most commercial sites (research RSA) even a key table is useless (which is the purpose) since it will simply spit out different data every time even if the same data is input.

In an advanced asymmetrical system of encryption, Data is input by the user, based on "random" values that are meant to be specific to a point in time (a session) that way they aren't simply reproduced, that data is encrypted and then on top of that a key is sent along to the server to be decoded and then therefore used to decode the user data. The keys in the system is usually the consistency of the random encryptions I guess that would be the flaw.
Even then brute forcing isn't worth your time unless you want something to be shown even after your death. Parallel processing is expected to make current conventional methods of encryption useless.
Today modern processors, process everything linearly, Parallel processing will truly allow for many multiple threads processing that are truly independent of one another unlike currently linear processing where the end result has to be stream-lined into one "logical" linear flow of data. If your a real Geek this kind of stuff about Parallel processing turns you on.

I hesitated from responding the first time because I wasn't sure how I should address it because it was a ridiculous request in so many ways because you obviously don't know the work that is involved in this kind of thing.
