cero's Issues

Crypto Go ：we are a research group to help developers build secure applications.

Hi, we are a research group to help developers build secure applications. We designed a cryptographic misuse detector (i.e., CryptoGo) on Go language. We found your great public repository from Github, and several security issues detected by CryptoGo are shown in the following.
Note that the cryptographic algorithms are categorized with two aspects: security strength and security vulnerability based on NIST Special Publication 800-57 and other public publications. Moreover, CryptoGo defined certain rules derived from the APIs of Go cryptographic library and other popular cryptographic misuse detectors. The specific security issues we found are as follows:
Location: cero.go:178;
Broken rule: SSL/TLS use insecure verification;
We wish the above security issues could truly help you to build a secure application. If you have any concern or suggestion, please feel free to contact us, we are looking forward to your reply. Thanks.

✨ Update to go 1.19

Options and targets are misplaced in docs

cero --help
usage: cero [options] [targets]

cero -v -d -t 5 192.168.0.2:3389
192.168.0.2:3389 -- []

cero 192.168.0.2:3389 -v -d -t 5
DESKTOP-120ABCD

How to save the output to maybe .txt file

How can I save the output after using eg cero -d 1.1.1.1/24

Feature Request: add -org flag to show organization.

so it will show:

subdomain.com [organization]

in the output.

Does not work

I clone cero but when i run the command cero it does not work.why?

Implement support for IPv6
