Revision 7. </p> <p>This code enable decimal base conversion according map length and a different char set.</p> <p>Example:</p> <ul> <li>map = ['0','1'] base 2 10 -> 1010</li> <li>map = ['a','b'] base 2 10 -> baba</li> <li>map = ['a','b','c','d','e','f','g','h','i','j','k','l'] base 12 10 -> k</li> <li>map = ['a','b','c','d','e','f','g','h','i','j','k','l'] base 12 100 -> ie</li> </ul> <p>this simple method can be used in web sites to hide a well known decimal sequence like user ids.</p>
