Hello gurus: In the book "Network Security with OpenSSL", it claims (at page 26) that "a public key can be derived from the private key". This is against what I learned that there is no way to retrieve one from the other in the key pair.
I am trying to understand what that means. I can use openssl to generate a private key, say by "openssl req -new -x509 -key private.pem ...". Then I can use "openssl -in private.pem -pubout -out public" to obtain the public key. So I am assuming that is what it is saying about "a public key can be derived from the private key". Am I right at this point? If I am right, I think there must be some extra information saved in the file private.pem other than the private key itself, so that together the public key can be obtained. Then, the content/format of the privatekey file should be defined in a standard way. What is it then? should it be protocol independent?
