Base 2 2 the 6

We are given this string:

Q1RGbGVhcm57RmxhZ2d5V2FnZ3lSYWdneX0K

Since it has numbers, lowercase letters and uppercase letters, it seems to be encoded in Base64.

Actually, the name of the challenge is “2 2 the 6” (“2 to the 6”), so $2^6 = 64$.

We can decode it using a shell:

$ echo Q1RGbGVhcm57RmxhZ2d5V2FnZ3lSYWdneX0K | base64 -d
