Identify encoding type

Question

I'm in the process of analysing some web log files. There are parameters passed for some requests which are encoded. I tried this to decode it, but it cannot identify the encoding schema. Do you have any idea on what this encoding type is?

Answer 1

That looks like a urlencoded base64 string.

The data seems to be something unreadable so I dumped it in HEX:

67AB2915D96A0DA5CC8DDA034E232F3D2FF783C2009A65BF1AA4C70B

Some more hints that % sign is followed by two hexadecimal letters e.g. %2F is / that output ends with == with is very typically for base 64
