This is the ssl.key/ directory of Apache/mod_ssl where PEM-encoded RSA Private Keys for SSL are stored. Per default the following files are provided: o server.key: This is the server private key for Apache/mod_ssl, configured with the SSLCertificateKeyFile directive. Per default this is a dummy file, but may be overwritten by the `make certificate' target under built-time. o snakeoil.key: This is the private key of the _DEMONSTRATION ONLY_ `Snake Oil' Server. It corresponds to the dummy server certificate ../ssl.crt/snakeoil.crt. NEVER USE THIS PRIVATE KEY YOURSELF FOR REAL LIFE! INSTEAD USE A REAL SERVER KEY! o snakeoil-ca.key: This is the private key of the _DEMONSTRATION ONLY_ `Snake Oil' Certificate Authority. It is used to sign the ../ssl.crt/server.crt on `make certificate' because self-signed server certificates are not accepted by all browsers. NEVER USE THIS PRIVATE KEY YOURSELF FOR REAL LIFE! INSTEAD EITHER USE A PUBLICALLY KNOWN CA OR CREATE YOUR OWN CA! You can view the ingredients of a particular private key file in plain text by running the command (a pass phrase may be queried): $ openssl rsa -noout -text -in .key
