So...I made my own encoding method...

[Awesomolocity]

String.prototype.aEncode = function(){
	var ar = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ,.!?/&#%=+-~_*'.split(''), a = this.length, x, y = '', z;
	var b = ar.length;
	if((a+2)%2 == 0){
		for(i = 0; i<a;i++){
			if((i+2)%2 == 0){
				x = ((ar.indexOf(this[i])-a)+b)%b;
				y += ar[x];
			}
			else{
				x = ((ar.indexOf(this[i])+a)+b)%b;
				y += ar[x];
			}
		}
	}
	else{
		for(i = 0; i<a;i++){
			if((i+2)%2 == 0){
				x = ((ar.indexOf(this[i])+a)+b)%b;
				y += ar[x];
			}
			else{
				x = ((ar.indexOf(this[i])-a)+b)%b;
				y += ar[x];
			}
		}
	}
	return y;
}
String.prototype.aDecode = function(){
	var ar = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ,.!?/&#%=+-~_*'.split(''), a = this.length, x, y = '', z;
	var b = ar.length;
	if((a+2)%2 == 0){
		for(i = 0; i<a;i++){
			if((i+2)%2 == 0){
				x = ((ar.indexOf(this[i])+a)+b)%b;
				y += ar[x];
			}
			else{
				x = ((ar.indexOf(this[i])-a)+b)%b;
				y += ar[x];
			}
		}
	}
	else{
		for(i = 0; i<a;i++){
			if((i+2)%2 == 0){
				x = ((ar.indexOf(this[i])-a)+b)%b;
				y += ar[x];
			}
			else{
				x = ((ar.indexOf(this[i])+a)+b)%b;
				y += ar[x];
			}
		}
	}
	return y;
}

Usage:

'somestring'.aEncode();//iycoiDhsdq

Not exactly sure why someone would use it, but it's cool. I guess it would be nice for like...keeping messages or a password secret.
