Reality - TLS - Scanner

Building

Requirement: Go 1.21+

go build

Usage

It is recommended to run this tool locally, as running the scanner in the cloud may cause the VPS to be flagged.

# Show help
./RealiTLScanner

# Scan a specific IP, IP CIDR or domain:
./RealiTLScanner -addr 1.2.3.4

# Scan a list of targets from a file (targets should be divided by line break):
./RealiTLScanner -in in.txt

# Specify a port to scan, default: 443
./RealiTLScanner -addr 1.1.1.1 -port 443

# Show verbose output, including failed scans and infeasible targets:
./RealiTLScanner -addr 1.2.3.0/24 -v

# Save results to a file, default: out.csv
./RealiTLScanner -addr www.microsoft.com -out file.csv

# Set a thread count, default: 1
./RealiTLScanner -addr wiki.ubuntu.com -thread 10

# Set a timeout for each scan, default: 10 (seconds)
./RealiTLScanner -addr 107.172.1.1/16 -timeout 5
