Question

How is the blob of text encoded? Base64? Something else?

Answer 1

+7 A:

It may easily be anything, but since it contains mixed-case letters and numbers and few symbols, my guess is for base64.

Addendum

Yes, it is definitely base64; it seems some kind of HTTP request, but it contains some strange characters, I don't know if it's garbage or binary data with some meaning.

+1, looks very much like base64

@Saravanan I M: So what? Maybe it is binary data. One cannot tell if one does not know where it comes from. Btw. encoding != encryption.

Yep with some JavaScript in it

Answer 2

+4 A:

This is definitely base64, decoding the first line gives you meaningful data, the beginning of HTTP packet dump.

+6 A:

Base64

I've run a decoder on it (the whole lot) and this is the result:

This is part of a HTTP response, I'm guessing the gibrige is most likely due to a charset or you've pasted so much of it only. What you're getting is the result of decoding the first few lines only.

that's not garbage, that's IP and TCP headers

unbeli 2010-06-21 10:16:26

Please it is **not** *decryption*. It is *decoding*. This is a very important difference and can lead to misunderstandings.

Felix Kling 2010-06-21 10:20:52

@Felix Kling typo, fixed. Thanks for the heads up :)
