astgenkey: generates keys for for Asterisk IAX2 RSA authentication
NAMEastgenkey -- generates keys for for Asterisk IAX2 RSA authentication
astgenkey [ -q ] [ -n ] [ keyname ]
DESCRIPTIONastgenkey This script generates an RSA private and public key pair in PEM format for use by Asterisk. The private key should be kept a secret, as it can be used to fake your system's identity. Thus by default (without the option -n ) the script will create a passphrase-encrypted copy of your secret key: without entering the passphrase you won't be able to use it.
However if you want to use such a key with Asterisk, you'll have to start it interactively, because the scripts that start asterisk can't use that encrypted key.
The key is identified by a name. If you don't write the name on the command-line you'll be prompted for one. The outputs of the script are:
- The public key: not secret. Send this to the other side.
- The private key: secret.
Those files should be copied to /usr/share/asterisk/keys
(The private key: on your system. The public key: on other systems)
To see the currently-installed keys from the asterisk CLI, use the command
- show keys
- Run quietly.
- Don't encrypt the private key.
SECURITYThe keys are created, using the umask of the user running the command. To create the keys in a secure manner, you should check to ensure that your umask is first set to disallow the private key from being world- readable, such as with the following commands:
And then make the key accessible to Asterisk (assuming you run it as user "asterisk").
