$ openssl x509 -noout -text -in server.crt
To view the Certificate and the key run the commands: To check that the public key in your cert matches the public portion of your private key, you need to view the cert and the key and compare the numbers. The "public key" bits are also embedded in your Certificate (we get them from your CSR).
Two of those numbers form the "public key", the others are part of your "private key".
Openssl verify certificate and key series#
The private key contains a series of numbers. (Shamelessly stolen from (and expanding upon) The Apache SSL FAQ) Be sure you understand what you are doing. Note: It should be noted that this is not a UW-Madison Help Desk or DoIT Middleware supported procedure, and, naturally, we can't take responsibility for any damage you do while following or attempting to follow these procedures.
