打开 David's words.txt ,发现一串有规律的数字

txt

David, the father of King Solomon of Israel, played the harp well and was described as the most righteous of Kings.

King David was lost，and he loved the Weird Numbers.
Before he left, he said something odd and left the weird number: "Only A is 1. Who will save me?"
Cound you find him?

看完 hint 了吗？不妨停下来仔细思考！

......

根据“Only A is 1”，猜测将 A 替换为 1，同时观察发现数字串 2345678910 反复出现，整体替换为 0，得到二进制文本，转换成 ASCII 码：SGFwcHkgdG8gdGVsbCB5b3Uga2V5IGlzIEtleXtPTUdfWW91ZG9pdH0=

识别为 Base64 编码，解码得到信息：Happy to tell you key is Key{OMG_Youdoit}

K.jpg 实际上是个 zip 文件，改后缀名，利用刚才得到的密码解压，有两个文件 Ancient spells.txt 和 K.jpg

As long as you help me to fix, I'll give you what you want.

查看图片，根据提示和图片内容猜测图片高度被修改过，在 010 Editor 中修改高度得到完整图片；用 StegSolve 打开，多点几次 ">" 观察可得：flag{Poker_F@ce}
