以下の文字列が与えられた。
This string was given:
一見Base64のように見えるが、通常は最後にしか来ないはずの = が途中に入っている。
g{ を含む結果が得られず、違うようだった。
This looks like Base64 at first glance, but a character =, which normally should appear only at the end, is in the middle.
I thought that the order of characters may be shuffled, and analyzed using this program.
As a result, no combination of 4 characters yielded g{ and I found this hypothesis should be wrong.
試行錯誤の結果、
After some trial-and-error, I obtained the flag by decoding using "From Base64" on
