We were given a string which was base32 encoded. `GN2WUSTOLFYTCWKQLFLG65KBNVDEGMRUMMZTM4LVOFUG2R3LMNWTKTCMGVWVUR3WOM3HONDNMV3UOOKDM4ZWUTDIK5FGOY3EJV4VIMKFJUYVUWLQGJRUGYLCOQ3HG6LVHFXUC3TKJRSW6RDLNFFEWZ2TG4`

From the Challenge Description, it was clear that we had to decrypt the string using all the bases in increasing order.

The order was Base32 -> Base58 -> Base62 -> Base64 -> Base85.

The decoding was done using [Cyberchef](http://icyberchef.com/#recipe=From_Base32('A-Z2-7%3D',true)From_Base58('123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz',true)From_Base62('0-9A-Za-z')From_Base64('A-Za-z0-9%2B/%3D',true)From_Base85('!-u')&input=R04yV1VTVE9MRllUQ1dLUUxGTEc2NUtCTlZERUdNUlVNTVpUTTRMVk9GVUcyUjNMTU5XVEtUQ01HVldWVVIzV09NM0hPTkROTVYzVU9PS0RNNFpXVVRESUs1RkdPWTNFSlY0VklNS0ZKVVlWVVdMUUdKUlVHWUxDT1EzSEc2TFZIRlhVQzNUS0pSU1c2UkRMTkZGRVdaMlRHNA).
