@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

@mike197312
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

@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.

Anyone have any problems with Cyberchef not decoding multiple lines?
I am trying to decode multiple lines of RC4 and it seems to only be decoding one line at a time. Any ideas?
bwhitn
@bwhitn
Got an example?
Sh311c0d324
@Sh311c0d324
I do, give me a second.
That's the issue I opened and it has some examples.
bwhitn
@bwhitn
@Sh311c0d324 Not 100% sure but you may want to try the fork function at the beginning of the recipe.
Sh311c0d324
@Sh311c0d324
Fork function?
I'll take a look, thanks!
The fork function worked! Thanks so much for your help @bwhitn

Hello :) I have more of a general question (I hope it's OK to ask this here) it's a simple one. I am learning about cryptography and I am just looking to perform a really basic encryption/decryption with cyberchef using DES3. I want to take a string "The elephant was pink" and encrypt it. Then share that encyption with some friends and challenge them to decrypt it :) I am getting "invalid key length" errors.

(Or if anyone could recommend a good resource to learn more about this, I am really grateful!)

Is there a way to "add" text to the input?
I mean "concat" or this kind of things

Not so much of a bug but the DNS over HTTPS recipe only accepts 1 host input - would be superhandy if it could accept a list instead?
Matthew
@yaekmj_twitter
ahh, just scrolled up and found mention of the fork recipe - that before DNS over HTTPS recipe = win ! Thanks for mentioning fork @bwhitn :)
