Error: "SSL Library Error: 185073780 error:0B080074:x509 certificate routines:X509_check_private_key:key values mismatch" may occur in the process of installing an SSL certificate on an Apache server.

In general, the above error occurs when using an incorrect key with the SSL certificate received from the issuing authority.

To check if the SSL certificate matches the RSA key run the following commands:

openssl x509 -in /cale/catre/certificate.crt -noout -modulus | openssl sha1
openssl rsa -in /cale/catre/private.key -noout -modulus | openssl sha1

Make sure the two results match.
