OpenSSL команды для проверки SSL сертификатов, ключей


Check a certificate

Check a certificate and return information about it(Signing authority, expiration date, etc.)
openssl x509 -in server.crt -text -noout

Check a key

Check the SSL key and verify the consistency
openssl rsa -in server.key -check

Check a CSR

Verify the CSR and print CSR data filled in when generating the CSR.
openssl req -text -noout -verify -in server.csr
 

Verify a certificate and key matches

The following two commands will print out md5 sums of the certificate and key. These sums can be compared to verify that the certificate and key match.

openssl x509 -noout -modulus -in server.crt| openssl md5
openssl rsa -noout -modulus -in server.key| openssl md5
