编解码算法工具bse.exe
强悍的可见流编解码工具bse.exe，比certutil快3倍的编码速度。支持9种编码格式，支持6种解码格式。由于汇编不是太熟，用C语言实现的只能每秒编码600M到1300M，我觉得已经够用了，因为机械硬盘每秒才读写50M，根本写不过来。使用：

其中base64+和base64#为自创编码算法，其原理如下：
我根据Base64的构造方式，改良了一种新的编码。这种编码方式与base64具有一样的编码增长率，只是编码的方式略有区别，是一种模拟的base256码，只是可见字符无法达到256种，因此为可见字符构建了引码。引码的取值为0x00、0x01、0x10、0x11，由4个引码与64个可见字符组合成256种不同情况，即组合为一个字节。在编码时，将8位的前两位单独取出作为引码，余下6位直接转化为数据码，同时每3个引码（也就是凑够6位）合成为一个base64+码。这样引码和数据码都转化为了base+码。
