Usage: crt [options...] 

NOTE:

  → Options must come before Input (Unless using -i)

  → Each connection is opened only for 5 Mins, with 3 Retries

  → NRD Indicator needs at least 3 Results to be Accurate

  → To pipe to other Tools, use -q 2>/dev/null | ${TOOL}

  → For Bulk mode, Always use -o to prevent Data Loss

Options:

  -e        Exclude Expired Certificates [Default: False]

  -s        Enumerate Subdomains [Default: False]

  -c   Number of concurrent lookups for Bulk Mode [Default: 5]

  -d   Delay between requests in milliseconds [Default: 500]

  -i  Input file containing domain names (one per line) for bulk lookup

  -l   Limit the number of results (more results take more time) [Default: 10]

  -o  Output file path [Default: STDOUT]

  -r   Number of retries for failed requests [Default: 3]

  -csv      Turn results to CSV

  -json     Turn results to JSON

  -jsonl    Turn results to JSONL (JSON Lines)

  -q        Quiet mode (Hide progress messages, only show results) [Bulk Mode Only]

Examples:

  crt "example.com"

  crt -s -e "example.com"

  crt -json -o logs.json "example.com"

  crt -l 15 -csv -o logs.csv "example.com"

  crt -jsonl -q -s "example.com" 2>/dev/null | jq -r ".subdomain"
