cipux_mkcertkey - simple script to generate certificate for stunnel
In order to add security to your XML-RPC server you should generate a
certificate. This script shows a simple method to do that. You have to take
the responsibility by yourself to make sure you understand what you do.
Generates a certificate and a key in /etc/cipux/stunnel.
Each SSL enabled XML-RPC server needs to present a valid X.509 certificate to
the peer and it also needs a private key to decrypt the incoming data. The
easiest way to obtain a certificate and a key is to generate them with the
free openssl package. You can find more information on certificates generation
below. The certificates must be in PEM format and must be sorted starting with
the certificate to the highest level (root CA)
Two things are important when generating the certificate-key pairs.
(1) Because the server has no way to obtain the password from the user, the
private key cannot be encrypted. To create an unencrypted key add the
"-nodes" option when running the req command from the openssl kit.
(2) The order of contents of the .pem file is also important. It should contain
the unencrypted private key first, then a signed certificate (not certificate
request). There should be also empty lines after certificate and private key.
Plaintext certificate information appended on the top of generated certificate
should be discarded. So the file should look like this:
-----BEGIN RSA PRIVATE KEY-----
-----END RSA PRIVATE KEY-----
This can be stored in one file or in two files. This script stores the in to
files to have the flexibility to use the certificate in other location. This
to files will be created:
TODO: write explanations to the messages.
- "Cannot find certificate configuration: %s"
- "Cannot find openssl executable: %s"
- "Directory to store certs do not exist: %s"
- "Directory to store certs is not save!..."
Directory to store certs is not save!
Should be for example:
drwx------ 2 root root 4096 2008-04-17 21:15 /etc/cipux/stunnel
- "Cannot execute %s"
- "Can not close %s"
- "Can not print to STDOUT!"
- "%s not known to the system!"
