Ruby B64 encoding & decoding class

[Caustik]

Hi. This is a simple class written in Ruby, which is to encode and decode integers into their b64 equivalent.

#B64 encoding in Ruby

#You must retain this notice if you wish to use it


class B64


    def self.encodeInt32(value,length)
    
        stack = ""
        1.step(length) { |x|
        
            offset = 6 * (length - x)
            val = (64 + ( value >> offset & 0x3f))
            stack << val
        }
        
        return stack
    end
    
    def self.decodeInt(strVal)
        val = strVal
        intTot = 0
        y = 0
        x = (val.length - 1)
        while x >= 0
            intTmp = ((val[x] - 64))
            if y > 0 then
                intTmp = intTmp * ((64 ^ y))
            end
            intTot += intTmp
            y += 1
            x -= 1
        end
        return intTot
    end
end

This class serves two static methods; encode and decode. You can use this as so:

#require 'b64.rb' if you have it elsewhere
puts B64.encodeInt32(12,2)
puts B64.decodeInt("@L")

Enjoy!
(VL64 should be coming soon - having a bit of difficulty atm. If you want me to release encoding and decoding for the new protocol, I will.)

This is based off JoeH's class

Why ruby?
I think it's good, but I don't like ruby really much. Good job.

Ruby's a nice language, good for simple, on the fly stuff :P

I don't know what it is, but that code makes my head explode;s

It's the Base64 encoding to convert for example @A into 1 written in Ruby.
It's the encoding for Habbo V5 - R63a

I'm no Ruby user, but from what I can see there is already a Base64 module for Ruby. Why reinvent the wheel?

But good effort either way.

In C# there's also something with B64, but it isn't the same as 'Habbo's B64'

There's a difference.. That's why I try refrain from calling it Base64

Oh, right. The file looks slightly confusing this way.
