What encoding is this?

[moishy]

Below is a short sample of a encoded message, does anybody recognize what encoding this is? It is not base64.

Looks like a bunch of jibberish to me. Where did you get it from?

[drhowarddrfine]

Then it could be Digest or MD5 but it could be anything.

[pbmods]

59 characters? It's not a standard md5 or sha1 hash. Probably proprietary.

[RedSon]

Can you give us the hex dump of it instead of the characters?

[moishy]

I just gave you a short sample, Below is the full version:

It comes from a YouTube internal error page and I'm eager to decode it!

Ah well then let us know how it goes.

[Motoma]

Below is a short sample of a encoded message, does anybody recognize what encoding this is? It is not base64.

What makes you think it is not Base64? The character set is identical, so I would assume that Base64 is at least the first step in the process of deciphering this string.

It is not Base64!
It contains invalid characters to be Base64

Decoding it using Base64 came out like this: (first three lines)

Oh?

Which ones?

Wikipedia's article on Base64 states:

...There are other variants that use '_-' or '._' when the Base64 variant string must be used within valid identifiers for programs....

so in this situation _ and - may very well be appropriate characters for the data. Judging by the character set, I am strongly leaning towards base 64 as the first stage of encoding.

[moishy]

What are you talking about?
See for yourself, the decoded string using Base64 doesn't come close to anywhere!

If your so sure it's Base64 then go ahead and decode it! There are many online decoders, but the decoded string looks worse than the original string!

Unless you take a second to consider that the result might very well be binary data, in which case is is perfectly reasonable to base-64 encode it to incorporate in an error message (for logging purposes, in a database perhaps).

Deep breaths, everyone. Deep breaths.

It's probably just a chunk out of the middle of a video stream or something.
