Verify cert and private key of pair created using EC algorithm

 

Retrieve the public key from cert and do a md5

openssl x509 -in server.crt -pubkey -noout | openssl md5

 

Retrieve the public key from private key and do a md5

openssl pkey -pubout -in server.key | openssl md5

If the outputs from two commands match, then the certificate must be created from the private key.
