Hi. Fantastic program or App, what ever you would call it. I was wondering if you would add Crockford base32 encode and decode? I used the search and it didn't come up. Many thanks for this fantastic suite.

@mattnotmitt

@737simpilot Oh thanks for reminding me! I've been meaning to add that, I'll see when I can get around to it.

Aaron

@737simpilot

Thanks.

Hi @n1474335 sorry to bother you. Would you recommend some further improvements to #653 before it can be merged? I'm in the process of writing up my CV for summer internships and it would be really nice if I could add that in :P

@n1474335

@cbeuw Merged. Nice work :thumbsup:

Hi. Nice work with this. Can you add an option where i could refang the URLs I defanged? Or is there already such functionality? Many thanks.

Hey

For some reason I just am not able to get this to deploy online. I'm not sure what I'm doing wrong

Running this off of Ubuntu 16.040

Starting to feel paranoid of 'Cyberchef'. This deployment acts very weird

@n1474335

Could you give some details?

@ProtoBuffers_twitter

does cyber chef support the newest version of protobuffs?

trying to get a json or/and hex file to a protobuf file but it seems all i get is numbers

n1474335

@n1474335

Not sure. Could you create an issue including the data you're trying to decode and what you would expect out?

Arthur

@ProtoBuffers_twitter

Save0001.sav

this is the raw file that is in protobuffs

Save0000.sav

here is what i'm aiming to get

Arthur

@ProtoBuffers_twitter

Save0001.sav

this was the original file

@NivagSwerdna_gitlab

it is possible to use Register to get say the last 32 characters from input and then drop those? e.g. a tag added to end of input?

answer my own question... drop bytes can take a -ve; which is relative to file end, so drop -32, 32 kills last 32 bytes

and (.{32})$ for the register

thx; for such a great tool

n1474335

@n1474335

@NivagSwerdna_gitlab It would probably make sense for us to add an option to the Register operation where it drops the selected bytes from the data. But yes, you can use Drop Bytes or Find/Replace to get rid of them currently.

@ProtoBuffers_twitter Can you raise an issue with that information? https://github.com/gchq/CyberChef/issues/new/choose

Aaron

@737simpilot

Have you implemented Crockford base32 yet?

@s2224834

@737simpilot You can encode/decode by just specifying the alphabet manually like this: https://gchq.github.io/CyberChef/#recipe=To_Upper_case('All')From_Base32('0-9A-HJKMNP-TV-Z',true) I don't think there's a way of doing the optional check symbol at the moment, though.

Aaron

@737simpilot

Okay, thanks.

Aaron

@737simpilot

I can't for the life of me find the upper case option so I can do this myself. Under what list is it?

@737simpilot just type "upper" in the search box, but it's under "utils"

Aaron

@737simpilot

@aryasenna Currently we only support Node v10 as one of the dependencies causes issues in later versions

Do you think you guys could add a landing page to https://gchq.github.io that you could click through to different projects? I often find myself there when i let my omnibox in my browser autofill to cyberchef :laughing:

@n1474335

There has been a plan in the works for a while to do something like this. I'm not sure where it has got to as I'm not involved in it
