生成OpenSSL私钥和公钥

Question

I have a task: generate private/public key pairs for banks.

User data like State, City, Company, Name, Email, and some other data should be included. How I can generate those keys with PHP or Shell?

UPDATE 1

I need a private key and cert for a Bank.

Answer 1

PHP offers interface to OpenSSL functions. You need to generate a certificate (the keypair can't include user data), and this is a bit more complicated than generating a keypair. You can generate self-signed certificates (in such certificates Issuer and Subject fields are identical), which is probably what you need.

If you need a CA-signed certificate, than you need to generate a certificate signing request (CSR) and a private key, then send a CSR to the certificate authority that will sign it and send you back the certificate (remember that private key remains on your side, so you need to save it).

Also, google search revealed a good tutorial for you.
