1. 得到了三百多张黑白颜色的图片，将白色图片转为数字0，黑色图片转为数字1，得到二进制字符串

011001100110110001100001011001110111101101100010011000010110000101100110001100000011000100110011011001000010110101100110001100110110011001100001001011010110001001100011011000100110010100101101001100000011000001100110011000100010110100110001011001010011000101100001001100110011010001100010011000100011001001100001011001100011000101111101

2.在网站上解码，二进制转字符串即可

第二题

1.在PDF上有base64，解码后得到一句话

The password is not just about decoding, but also hacking the ZIP!

2.在pdf中可以分离出zip，为真加密，将1.中解码得到的字符串存为txt，与zip明文爆破

3.打开后得到一张png，根据提示（png名字）用Stegsolve，过滤0通道，得到flag
