编解码算法工具bse.exe
本帖最后由 happysxyf 于 2017-1-18 20:35 编辑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：
bse [-e|-e#|-e+|-eb|-ex|...-d|-d#|-d+|-db|-dx|...] [输入文件] [输出文件]
__________________________________________________________________________________
选项：
-h 帮助信息
-e 编码为 BASE64
-e# 编码为 BASE64#
-e+ 编码为 BASE64+
-eb 编码为 BIN码
-ex 编码为 HEX码
-e92编码为 BASE92
-d BASE64 解码
-d# BASE64#解码
-d+ BASE64+解码
-db BIN码解码
-dx HEX码解码
-d92BASE92 解码
-m 制作标准 BASE64 批处理脚本
-mp 制作压缩 BASE64 加权批处理脚本
-md 制作兼容 BASE64 过滤论坛特殊词脚本
__________________________________________________________________________________
示例：
bse -e a.jpg a.base64 //将图片a.jpg编码为 BASE64
bse -e# a.jpg a.base64# //将图片a.jpg编码为 BASE64#
bse -e92 a.jpg a.base92 //将图片a.jpg编码为 BASE92
bse -d a.base64 a.jpg //将a.base64 解编码为 a.jpg
bse -d# a.base64# a.jpg //将a.base64#解编码为 a.jpg
bse -d92 a.base92 a.jpg //将a.base92 解编码为 a.jpg
bse -m a.jpg a.bat //将图片编码为“标准BASE64编码”批处理
bse -mp a.jpg a.bat //将图片编码为“压缩BASE64加权”批处理
bse -md a.jpg a.bat //将图片编码为“过滤论坛特殊词”批处理

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。
