Someone can gimme an hand decoding a base64 binary blob?

Hello :) I just used cybetchef to extract a .bin archive file. And i got about 1000 .zip files as output (extracted_at_0x0.zip, extracted_at_0x281.zip, ext.... ). They are all of different total size, so I assume those are different archive versions/backups. When I try to unzip the first .zip file (extracted_at_0x0.zip), I get 1000 files with .dat extention (0.dat, 1.dat,...999.dat), but some of the number file names are not int and have special char in them like $. Not sure that is some sort of currpotion?. So Opening the first file 0.dat gives me an error of "unexpected end". And trying to open any of the other ones yields an error "cannot open file as archive". So, the 1st zip contain 1000 of .dat files, and there are 1000 .zip each with 1000 .dat files in them. is there a way to combine/extract those together to form the original file, so it can be unzipped and files accesses ? thanks!!

HI
I am facing issue in arabic AES conversion
can anyone help?

@burhanuddin353 If I had to make a guess the AES Encrypt/Decrypt functions are handling the input output wrong. My guess is it should be treating raw as UTF8 but as raw is not an option type for the Utils.convertToByteString function it handles it the same as latin1 so it doesn't get the utf8.encode. Until it gets fixed you could work around it by only doing latin1 characters via encoding and decoding to a latin1 format like base64 or hex. Looks like there are more issues around the aes encoding too but haven't fleshed it out completely.

I don't know if this tool is still being updated but can protos be added? ProtoLite/2/3 would be an awesome addition to this tool

This thing is amazing
nice job people, I'm just playing with it now but I think it will become another tool of mine
btw I noted the Analize Hash can't detect bycript I wonder why

Is it possible to produce a steganography result in cyberchef as in OutGuess ?

I have to decrypt a database and have this class file which should give me the "recipe". But I have no clue
can anyone help me
Whizzer87
@Whizzer87
It should be From Base64, To Base64, XOR, From Base64 To Base64 but can't get it to work

What is the default character set for android?

Looks like it should be utf8 which wouldn’t explain it

But when you choose Base64 there's a dropdown menu with options. Have no clue which one I need

@Whizzer87 to decode you should use from base64 with default settings and xor with the key copy and pasted and change hex to utf8
To encode xor the base64 with same settings

how can i add value From_Base64('A-Za-z0-9+/=',true)
mike197312
@mike197312
it let me allow just From_Base64 A-Za-z0-9+/=

I am new to AES GCM, please help how to resolve "AES Decrypt - Authentication tag does not match tag length." this issue.

I am new to AES GCM, please help how to resolve "AES Decrypt - Authentication tag does not match tag length." this issue.

Hi @SapanJain321, The AES-GCM cipher with a key, a given IV and the ciphertext to be encrypted, returns as result the ciphertext and a tag value (AES_GCM is an AEAD cipher). This tag value must be entered - in the "GCM tag" field - when decrypting the ciphertext using the same key and IV. Try it and let us know your experience.

Was just toying around and wondered if there was a super simple "swap- like" operation. E.g., swap "A" with "K", "B" with "Z", etc., and vice versa everywhere. I know Substitute can be used but that involves more typing. In addition, it would be nice for swaps to have the option of being case insensitive, e.g., swapping "A" for "K" would also swap "k" for "a".

@n1474335
Substitute is probably your best bet. Another option would be Find/Replace.

@n1474335 OK, thanks.

I am wondering how I can run my prod version of CyberChef after I build with "grunt prod". There is a build/prod directory created with files inside, but how do I deploy this say on a Windows machine?

Hi All I am very green to cyber Chef but I have an assigment to try and unscramble a text file. I have read and watched a few vidoes here but I am still lost of on what I am doing ? Is there an easy way to unscramble a file ?
I am after some steps so I can understand it
Aaron
@737simpilot
What you would need to do is learn about entropy and look under Other and flow control for recipes to help. The biggest would be Magic under Flow control

Greetings - does CyberChef do Joaat hashing? I'm struggling to find that algorithm in the application, unless it is named something different.
n1474335
@n1474335
@AndromedusMr_twitter No, it doesn't currently support Joaat hashing, but if you'd like to write it yourself and submit a PR we would look at including it

Hey there. Where do I see what is the correct input format for an operation? Protobuf deode fails with "Error: Unknown type 0x4" if I put "to hex" before it and "Error: Unknown type 0x3" is I use the base64-decoded values directly.
