你以为是md5吗

文本内容：

bci177a7a9c7udf69c248647b4dfc6fd84o
我认为不是MD5……结果就是MD5，将不属于MD5的范围的字符去掉就可以了

flag{666666666666}

小山丘的秘密

将压缩包解压：
一张图和一个文本：

文本内容：

flag.txt 中给出A=1，一般的希尔密码是A=0，B=1, C=2 …所以字母表需要修改，现在的字母表为Z=0 , A=1 , B=2 …
那张图片是密码，所以密码为：123014560不是对应的字母：abczadefz，这里弄了好久

就得到了flag：
bugku{whatahill}

Math&English

下载附件，文本内容：

你会数学和英语吗? 3×7= 11×3= sin(Π/6)+sin(Π/6)= 2×11= 3×cos(2Π)= 22×2= 6×9= 2.5×2= tan(Π) + 1 = 5×7= 7×9-9= ln(e) + 2 = (6×6)-1= 4×10 + cos(0) = 26×2 = ln(e) × 10 +3 =
写出答案：

对应着元音表，就得到flag
