How do I verify that a private key matches a certificate? | |
To verify that a private key matches its certificate you need to compare the modulus of the certificate against the modulus of the private key. | |
Please follow the below command to view the modulus of the certificate. | |
# openssl x509 -noout -modulus -in server.crt | openssl md5 | |
Now you will receive the modulus something like a77c7953ea5283056a0c9ad75b274b96 | |
Please follow the below command to view the modulus of the private key. | |
# openssl rsa -noout -modulus -in myserver.key | openssl md5 | |
Now you should get the modulus as same as certificate modulus above. i.e a77c7953ea5283056a0c9ad75b274b96 | |
If the modulus of the certificate and the modulus of the private key do not match, then you’re not using the right private key. You can either create a brand new key and CSR and send contact support or do a search for all private keys on the system and compare their modulus. | |
Please follow the below command to search for all private keys on your server . | |
# find / -name *.key | |
openssl verify -verbose -CAfile file-ca.cer file-cert.cer | |
