🦑🔐 How to check the expiration date of a TLS / SSL certificate from the command line :

To check the expiration date of the SSL certificate, we are going to use the OpenSSL command line client.

The OpenSSL client provides a wealth of data including expiration dates, expiration dates, who issued the TLS / SSL certificate, and more.

Check the expiration date of the SSL or TLS certificate
Open the Terminal app and then run the following command:

$ openssl s_client -servername {SERVER_NAME} -connect {SERVER_NAME}:{PORT} | openssl x509 -noout -dates
$ echo | openssl s_client -servername {SERVER_NAME} -connect {SERVER_NAME}:{PORT} | openssl x509 -noout -dates

Let's find out the expiration date for www.undercode.help - enter:
DOM = "www.undercode.help"
PORT = "443"
openssl s_client -servername $ DOM -connect $ DOM : $ PORT \
| openssl x509 -noout -dates
Examples of output with dates and other information:
depth = 2 O = Digital Signature Trust Co., CN = DST Root CA X3
verify return: 1
depth = 1 C = US, O = Let's Encrypt, CN = Let's Encrypt Authority X3
verify return: 1
depth = 0 CN = www.undercode.help
verify return: 1
notBefore = Sep 29 23:10:07 2020 GMT
notAfter = Dec 28 23:10:07 2020 GMT
Add the echo command so you don't have to press CTRL + C.
For example:
DOM = "undercode.help"
PORT = "443"
## note echo added ##
echo | openssl s_client -servername $ DOM -connect $ DOM : $ PORT \
| openssl x509 -noout -dates
Understanding openssl command options
s_client: The s_client command implements a generic SSL / TLS client that connects to a remote host using SSL / TLS.
-servername $ DOM: Set the Server Name Indication (TLS SNI) extension in the ClientHello message to the specified value.
-connect $ DOM: $ PORT: specifies the host ($ DOM) and additional port ($ PORT) to connect.
x509: Runs the Certificate Display and Signature utility.
-noout: Prevents the output of the encoded version of the certificate.
-dates: Prints the start and expiration date of the TLS or SSL certificate.
Find the expiration date of an SSL certificate from a PEM encoded certificate file
The syntax is as follows: ask the certificate file when the TLS / SSL certificate expires.

$ openssl x509 -enddate -noout -in {/path/to/my/my.pem}
$ openssl x509 -enddate -noout -in /etc/nginx/ssl/undercode.help.fullchain.cer.ecc
$ openssl x509 -enddate -noout -in /etc/nginx/ssl/undercode.help.fullchain.cer
