Understanding OpenSSL Command Line Options

I am configuring OpenSSL. I can find endless resources to tell me what the commands are to do the basic tasks. I cannot seem to find anywhere that has information on what the commands and switches really mean. For example I look at this code:

Great I have a CSR. But I would like to know what -new. -newkey, -in, -out mean. I can figure out some but I can't find a resource that defines them. I have found openssl.org and modssl.org as inadequate as every source that quotes directly from them. I can find the syntax but no explanations. Anyone have any suggestions?
openssl genrsa -out server.key 1024
openssl req -new -key server.key -out server.csr
sign.sh server.csr

Open in new window

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

1. -out means "output to filename server.key which should be 1024 bits"
2. Create a Certificate Signing Request (CSR) with the server RSA private key and output the CSR key to server.csr
3. sight server.csr ( your certificate singning request ) using ca , thus creating a real ssl cert.
