Authentication System
Sending Authentication Credentials
We only require authentication on the domain registration and modification systems, since the whois and search systems are already freely available elsewhere. You will need to provide to CGI parameters, user and password.
The user parameter is the handle username you would normally use on the Registrar Console, for example H12345. This is normally created for you when you become a registrar but you can change it using the Registrar Console.
The password field contains your password encrypted using the one-way crypt() function. You should use the MD5 algorithm for this encryption.
The best way to force the use of MD5 is to supply an MD5 hex string as the salt to the crypt function. An MD5 salt consists of the string $1$, an alphanumeric string no longer than 8 characters, followed by another $. For example:
is a good MD5 salt.
