Encryption is very interesting and I've been thinking of an 'Eternity Code' for half a year now, one which cannot be cracked. I figure by using a sound as the method of input as in non-digital acoustic waves so there are too many possibilities to brute force :)

The problem with that is, how are you going to encrypt digital data with analog sound? At some point, the sound must be converted into bits. It would essentially be a very long key, longer than the 4,096-bit that's practical today.

I got a better idea.
  1. Make a film or short then use it as a key.
    • If it is a movie it would be a 1-4 GB key.
    • If it is a short then it would be a 10-100 MB key.
  2. Use a strong cipher.
  3. ???
  4. Profit

Back to topic guys please don't kill it.

im not asking to spoon feed me if iw anted you to spoon feed me i would just ask for the awnser of basic 6 :S .
i already readed that i know what they mean but i cant see what the Letter A has to do with decimal and stuff...

The point is that you give a decimal value in order since you think in decimals and not in binaries or in the cryptanalysis case in 256th base.

It is for YOUR commodity. If you are unintentionally trolling please stop.

It all basically comes down to this:

Every letter is assigned a number in order to let the computer understand it. If a cipher shifts by +13, then 13 is added to each number, which will now represent a different letter. That will be the encrypted Text. To unencrypted it, you subtract 13 from each number, and you're back at your original string.

Computers only really understand and electrical charge (+/-), generally called binary code. Every number is represented by a group of 0's and 1's. Decimal and Hexadecimal are shorthand ways of expressing Binary. Just like letters are a shorthand way of expressing the numbers which represent them.

I hope this helps.

I'll cut you. And I'd LOVE it if you would notice that I fixed that little typo.
