# lectl Script to check issued certificates by Let's Encrypt on CTL (Certificate Transparency Log) using https://crt.sh Note: crt.sh is property of Sectigo Limited 2015-2020 **Usage** ``` lectl [-h|--help] [-v|--version] [-l|--extraline] [-s|--sans] [-e|--expired] [-u|--utc] [-m] [-p|--pre] [-f|--final] domain ``` **Options** ``` -h | --help [Default: false] shows the help file. -v | --version shows the script version. -l | --extraline [Default: false] adds extra line separator between found certificates (when there are several certs with several sans adding this extra line it's easier to read the output). -s | --sans [Default: false] shows all domains included in the certificate as SANs. If you don't use this option you will only see the Common Name. -e | --expired [Default: false] shows all certs issued for the specified domain, including the certs that are already expired. -u | --utc [Default: false] shows the dates in UTC (GMT) instead of your machine time zone. -m [Default: 100] searchs for more or less than 100 certificates per domain OR subdomain. It means that if for example you use option -m25 you could receive an output of max 50 certs (25 for the domain and 25 for *.domain). If this option is not used, lectl searchs only for last 100 certificates. If the option is used it searches by default for last 1000 certificates. If you want to search for more or less certificates, append the number after the option with no spaces (Ex: -m500). If you specify a number, then the option must be specified independently. Wrong: lectl -seulm500 domain.tld Good: lectl -seul -m500 domain.tld -p | --pre [Default: true] shows only logged pre certs. -f | --final [Default: true] shows only logged final certs. ``` **Examples** ``` lectl letsencryt.org lectl -s -e -u -l -p letsencryt.org lectl -seulmf letsencryt.org lectl -lumsep letsencryt.org lectl -su --extraline letsencryt.org lectl -u letsencryt.org -esm --final lectl -seulp -m500 letsencryt.org ...and so on ```
