base64解密范例

今天才发现好多WordPress的模板都是把版权加密的，导致我们加个站长统计都费劲。加密方式多数是base64，就想迅雷的下载地址一样，现在根据自己的使用，写个解密的例子
1、工具，站长网的工具栏就够了，当然也有些人做成了解密软件

2、目标文件<?php $_F=__FILE__;$_X='Pz48P3BocCB3cF9mMjJ0NXIoKTsgPz4NCjwvZDR2Pg0KPC9kNHY+DQo8L2Q0dj4NCg0KPGQ0diA0ZD0iZjIydDVyLXdyMXAiPg0KDQo8ZDR2IDRkPSJmMjJ0NXIiPg0KPGQ0diBjbDFzcz0iYzVudDVyNWQtMSI+DQo8ZDR2IGNsMXNzPSJjNW50NXI1ZC1iIj4NCg0KPGQ0diBjbDFzcz0iZjIydDVyLWMybnQ1bnQiPg0KPGQ0diBjbDFzcz0iZmIxciI+DQo8M2wgY2wxc3M9ImYyMnQ1cl9sNHN0Ij4NCjxsNCA0ZD0ibTJzdC1jMm1tNW50NWQiPg0KPGhvPjw/cGhwIF81KCdNMnN0IEMybW01bnQ1ZCcpOyA/PjwvaG8+DQo8M2w+DQo8P3BocCBndDVfbTJzdF9jMm1tNW50NWQoKTsgPz4NCjwvM2w+DQo8L2w0Pg0KPC8zbD4NCjwvZDR2Pg0KDQoNCjxkNHYgY2wxc3M9ImZiMXIiPg0KPDNsIGNsMXNzPSJmMjJ0NXJfbDRzdCI+DQo8bDQgNGQ9InIxbmQybS01bnRyNDVzIj4NCjxobz48P3BocCBfNSgnUjFuZDJtIEFydDRjbDVzJyk7ID8+PC9obz4NCjwzbD4NCjw/cGhwIGd0NV9yMW5kMm1fcDJzdHMoKTsgPz4NCjwvM2w+DQo8L2w0Pg0KPC8zbD4NCjwvZDR2Pg0KDQoNCjxkNHYgY2wxc3M9ImZiMXIiPg0KPDNsIGNsMXNzPSJmMjJ0NXJfbDRzdCI+DQo8bDQgNGQ9ImY1MXQzcjVkLWMxdCI+DQoNCjw/cGhwICR0aDVfYzF0X3NsM2cgPSBnNXRfMnB0NDJuKCd0bl9rNWsyX2YyMnQ1cl9mNTF0M3I1ZCcpOyA/Pg0KDQo8P3BocCA0ZigoJHRoNV9jMXRfc2wzZyA9PSAnJykgfHwgKCR0aDVfYzF0X3NsM2cgPT0gJ0NoMjJzNSAxIGMxdDVnMnJ5OicpKXsgPz4NCg0KPGhvPkY1MXQzcjVkIG4ydCBzNXQgeTV0PC9obz4NCjwzbD4NCjxsND5TNXQzcCBmMjJ0NXIgZjUxdDNyNXMgNG4gPDEgaHI1Zj0iPD9waHAgNWNoMiBnNXRfczV0dDRuZ3MoJ2gybTUnKTsgPz4vd3AtMWRtNG4vdGg1bTVzLnBocD9wMWc1PWYzbmN0NDJucy5waHAiPnRoNW01IDJwdDQybjwvMT48L2w0Pg0KPC8zbD4NCg0KPD9waHAgfSA1bHM1IHsgPz4NCg0KPGhvPlI1YzVudGx5IDRuIDw/cGhwIDVjaDIgc3RyNHBjc2wxc2g1cygkdGg1X2MxdF9zbDNnKTsgPz48L2hvPg0KPDNsPg0KPD9waHANCi8vNG5zNXJ0IHkyM3IgYzF0NWcycnkgbjFtNQ0KJG15X3EzNXJ5ID0gbjV3IFdQX1EzNXJ5KCdjMXQ1ZzJyeV9uMW01PScuICR0aDVfYzF0X3NsM2cgLiAnJicgLiAnc2gyd3Ayc3RzPScgLiA4KTsNCndoNGw1ICgkbXlfcTM1cnktPmgxdjVfcDJzdHMoKSkgOiAkbXlfcTM1cnktPnRoNV9wMnN0KCk7DQokZDJfbjJ0X2QzcGw0YzF0NSA9ICRwMnN0LT5JRDsNCiR0aDVfcDJzdF80ZHMgPSBnNXRfdGg1X0lEKCk7DQo/Pg0KPGw0Pg0KPD9waHAgdGg1X3Q0dGw1KCk7ID8+PGJyIC8+DQo8NW0+PDEgaHI1Zj0iPD9waHAgdGg1X3A1cm0xbDRuaygpOyA/PiI+Q2w0Y2sgaDVyNSB0MiByNTFkIG0ycjUgJnIxcnI7PC8xPjwvNW0+DQo8L2w0Pg0KPD9waHAgNW5kd2g0bDU7Pz4NCjwvM2w+DQoNCjw/cGhwIH0gPz4NCg0KPC9sND4NCjwvM2w+DQoNCjwvZDR2Pg0KPC9kNHY+DQoNCg0KDQoNCjwvZDR2Pg0KPC9kNHY+DQo8L2Q0dj4NCjwvZDR2Pg0KDQoNCg0KPGQ0diA0ZD0iZjIydDVyLTIzdCI+DQo8ZDR2IGNsMXNzPSJjNW50NXI1ZC0xIj4NCjxkNHYgY2wxc3M9ImM1bnQ1cjVkLWIiPg0KDQo8ZDR2IGNsMXNzPSIxbDRnbmw1ZnQiPg0KPD9waHAgNG5jbDNkNSAoVEVNUExBVEVQQVRIIC4gJy9jMnB5cjRnaHQucGhwJyk7ID8+DQo8MSB0NHRsNT0iVzJyZFByNXNzIFRoNW01IEQ1djVsMnA1ciIgaHI1Zj0iaHR0cDovL3d3dy5tazVscy5jMm0iPkZyNTUgVzJyZFByNXNzIFRoNW01PC8xPiBieSBtazVscw0KPC9kNHY+DQoNCjxkNHYgY2wxc3M9IjFsNGducjRnaHQiPg0KQzJsbDFiMnIxdDQybiB3NHRoIDwxIGhyNWY9Imh0dHA6Ly93d3cuazJyNTFuLWNsMnRoNG5nLmMybS8iIHQ0dGw1PSJLMnI1MW4gQ2wydGg0bmciPksycjUxbiBDbDJ0aDRuZzwvMT4mbmJzcDsmbmJzcDt8Jm5ic3A7Jm5ic3A7PDEgaHI1Zj0iaHR0cDovL3d3dy50aDVwNGdneWIxbms1ci5jMm0vIiB0NHRsNT0iQ0QgUjF0NXMiPkNEIFIxdDVzPC8xPiZuYnNwOyZuYnNwO3wmbmJzcDsmbmJzcDs8MSBocjVmPSJodHRwOi8vd3d3LmIxbms0bmd6NW4uYzJtLyIgdDR0bDU9IkIxbmsgUjF0NXMiPkIxbmsgUjF0NXM8LzE+DQo8L2Q0dj4NCjwvZDR2Pg0KPC9kNHY+DQo8L2Q0dj4NCg0KPC9iMmR5Pg0KPC9odG1sPg==';eval(base64_decode('JF9YPWJhc2U2NF9kZWNvZGUoJF9YKTskX1g9c3RydHIoJF9YLCcxMjM0NTZhb3VpZScsJ2FvdWllMTIzNDU2Jyk7JF9SPWVyZWdfcmVwbGFjZSgnX19GSUxFX18nLCInIi4kX0YuIiciLCRfWCk7ZXZhbCgkX1IpOyRfUj0wOyRfWD0wOw=='));?>3、准备工作，加密的footer传上去，查看源代码<div id="footer-wrap">

比如 4=i 2=o 3=u 5=e
然后分别替换，注意有些带数字的标签也会被替换比如 h3会变成 ho，要注意改回去
