A random secret symmetric key to encrypt the data is created and then encrypted by public asymmetric key. Just google/wiki ‘hybrid encryption’.

]]> Comment on Maze62: a dense and speedy alphanumeric encoding for binary data by Alexey Tourbin http://blog.altudov.com/2011/05/16/maze62-a-dense-and-speedy-alphanumeric-encoding-for-binary-data/#comment-501 Mon, 19 Dec 2011 08:45:53 +0000 http://blog.altudov.com/?p=120#comment-501 Hello, there seems to be one problem which has to be addressed. Suppose the alphabet is 0-9A-Za-z and you need to encode 6 bits, all being zero. So you put ’0′ character, and then there’s another q=0 bit to clarify that this was actually 0 and not 62. With 5 trailing zero bits, you put the second ’0′ character but then again, by the rules, ’0′ has to be complemented by the q=0 bit, and so on. Thus by trying to encode a sequence of zero bits, you enter an infinite loop.

On the other hand, consider that you have to decode the string which consists only of ’0′ and ’1′ characters. What do you do? Suppose the first character is ’0′. You then you need to decode the second character to decide whether the first character was 0 or 62. But to complete the second character, you need to peek at the third character, and so on. And so you may end up with unlimited lookahead.

Thus the problem which has to be addressed is consecutive special characters. One possibility is to devise the algorithm which avoids them altogether (that is, guarantees that ’0′ or ’1′ is never followed by ’0′ or ’1′, so that only one-character lookahead is ever needed), but it would take slightly more bits. It may (or may not) be also possible, though, to tweak the algorithm so that multiple specials are handled gracefully.

I don’t think it’s utopian, at least in that this system makes economic sense for all parties involved, and allows expanding current market.
