__construct()
__toString(): string
string addFileFormat(string $fullname): boolean
The plugin needs to either already be loaded or be auto-loadable. Loading a plugin whose shortname overwrite an existing shortname will overwrite the old plugin.

createKey(\phpseclib3\Crypt\DH\Parameters $params,integer $length): \phpseclib3\Crypt\DH\PrivateKey
The rationale for the second parameter is described in http://tools.ietf.org/html/rfc4419#section-6.2 :
"To increase the speed of the key exchange, both client and server may reduce the size of their private exponents. It should be at least twice as long as the key material that is generated from the shared secret. For more details, see the paper by van Oorschot and Wiener [VAN-OORSCHOT]."
$length is in bits

This method is a bit polymorphic. It can take any of the following:
\phpseclib3\Crypt\DH\Parameters getComment(): null|string
Not all key formats support comments. If you want to set a comment use toString()
null|string getHash()
getLoadedFormat(): mixed
If the key that was loaded wasn't in a valid or if the key was auto-generated with RSA::createKey() then this will throw an exception.

mixed getParameters(): mixed
A public / private key is only returned if the currently loaded "key" contains an x or y value.
