今天同事惊奇的告诉我，说找到个在线的EditPlus注册码生成器，我赶紧去看了看，还真是，在这里。
exe的注册机病毒太多，纯js的在线注册机可就放心了。
作者是从别人的注册机反汇编然后找出算法的，更令我惊奇的是，这作者Demon竟然是搞法律的，才刚拿到法律职业资格证书，佩服。

主要的一个js函数是这样的：
function generate_editplus_regcode(username){
var list = [0,49345,49537,320,49921,960,640,49729,50689,1728,1920,51009,1280,50625,50305,1088,52225,3264,3456,52545,3840,53185,52865,3648,2560,51905,52097,2880,51457,2496,2176,51265,55297,6336,6528,55617,6912,56257,55937,6720,7680,57025,57217,8000,56577,7616,7296,56385,5120,54465,54657,5440,55041,6080,5760,54849,53761,4800,4992,54081,4352,53697,53377,4160,61441,12480,12672,61761,13056,62401,62081,12864,13824,63169,63361,14144,62721,13760,13440,62529,15360,64705,64897,15680,65281,16320,16000,65089,64001,15040,15232,64321,14592,63937,63617,14400,10240,59585,59777,10560,60161,11200,10880,59969,60929,11968,12160,61249,11520,60865,60545,11328,58369,9408,9600,58689,9984,59329,59009,9792,8704,58049,58241,9024,57601,8640,8320,57409,40961,24768,24960,41281,25344,41921,41601,25152,26112,42689,42881,26432,42241,26048,25728,42049,27648,44225,44417,27968,44801,28608,28288,44609,43521,27328,27520,43841,26880,43457,43137,26688,30720,47297,47489,31040,47873,31680,31360,47681,48641,32448,32640,48961,32000,48577,48257,31808,46081,29888,30080,46401,30464,47041,46721,30272,29184,45761,45953,29504,45313,29120,28800,45121,20480,37057,37249,20800,37633,21440,21120,37441,38401,22208,22400,38721,21760,38337,38017,21568,39937,23744,23936,40257,24320,40897,40577,24128,23040,39617,39809,23360,39169,22976,22656,38977,34817,18624,18816,35137,19200,35777,35457,19008,19968,36545,36737,20288,36097,19904,19584,35905,17408,33985,34177,17728,34561,18368,18048,34369,33281,17088,17280,33601,16640,33217,32897,16448];
