Create self-signed root certificate
The string of data you wish to sign signature. If the call was successful the signature is returned in signature. Resource - a key, returned by opensslgetprivatekey. String - a PEM formatted key. Generate an OpenSSL Certificate Request with SHA256 Signature Google have recently announced that they are going to start reporting that SSL certificates that are signed with a SHA-1 Hash will be treated as having a lower security than those signed with newer, higher strength hashes such as SHA-256 or SHA. O1t2KBkaSoR+JyOPOZakq5BLv8lgD3vefhF2z3Okx8lrfaYMDrCZbacpSGBu -END RSA PRIVATE KEY-. Both are PEM format, but the second is a RSA private key. With the second, PHP can login. So I need a key that starts with RSA PRIVATE KEY, not just PRIVATE KEY.
Set up directory structure for CA and configure
openssl.cnf
.Set
OPENSSL_CONF
environment variable - alternative to specifying -config
argument each time.Create SSL certificate
Common Name is the domain.
Sign the request by CA.
Install to Apache
Since the CA certificate is self-signed, Apache needs to serve the CA certificate in addition to the site certificate.
