error - gzip: invalid header

Hi, I downloaded the tool, and when I try to insert an API it gives me an error every time:

gzip: invalid header

Hello @israel9905,

Can you post the exact commands you were using? Providing more details to replicate the problem would be very helpful for us.

Thanks!

Regards, Marta

In Linux: When I enter an ip address, and an API it gives the error

in Windows: when I use the vt init command, it asks for the API, and after I put it in, it gives this error

Hello @israel9905,

vt-cli uses vt-go under the hood, which communicates with our API by setting a Accept-Encoding: gzip header and golang's gzip library to decompress the response.

Are you able to gzip decompress files using go? You can try this snippet to check it out: https://pkg.go.dev/compress/gzip#example-package-WriterReader

I did not understand, I would love for a more detailed explanation, thanks

Hello @israel9905,

The command client you're using does requests to VirusTotal and expects the response in gzip format. I asked you to test golang's gzip example to check if there's a problem in your go install: https://pkg.go.dev/compress/gzip#example-package-WriterReader

Regards, Marta

Okay, how do I check the command? Am I copying what is in the link to the terminal?

Hello @israel9905,

Let's change the direction of the troubleshooting. Execute the following commands on your kali:

Enter your API key: sdshdsdjkdhjkasasd
Wrong API key: sdshdsdjkdhjkasasd

You need to install the Go compiler (instructions here: https://go.dev/doc/install).

Thanks!

Hello @israel9905,

I followed the exact same steps on this docker image: https://hub.docker.com/r/kalilinux/kali-rolling

I needed the following additional steps to install dependencies:

Can you do the same steps on the docker image? I feel there's something wrong on your environment and the docker image is the best way to test a 100% clean environment from scratch.
