CaesarMirror was a combination of ROT13 (Caesar cipher) and reversing of strings. CyberChef made short work of it: Using ROT13 and Reverse to obtain the flag. The flag was:flag{julius_in_a_reflection} I Wont Let You Down was a rickroll. Jokes aside, visiting the provided website gave...
45对应ASCII“-”,42对应“*”,变成了-- *-- --* --* * *-* *--,恰好是Morse密码,解密得到mwggerw,Caesar解密一下得到isccans,即Flag。开始一直没想到Caesar,直到看到两个g连在一起,比赛的名字又有两个c,才联想到的。 Flag:isccans。
开始一直没想到Caesar,直到看到两个g连在一起,比赛的名字又有两个c,才联想到的。 Flag:isccans。 正则指令w{3}=www,目测是个网址,然后[xyz]表示一个xyz之一起始的域名,做这题的时候我恰好翻过墙,然后看到后面的watch和list想到了是youtube.com,翻墙进入页面:www.youtube.com/watch?v=5x1vNTjbwcs&list=PL...

Anyway, such simple coding is helpful for all sites that don’t allow dictionary attacks, such as those that lock out (temporary lock is best to avoid easy DoS) after a few missed attempts. But I prefer to use PasswordSafe on my desktop and laptop. Of course, this doesn’t help for ...
