Key Property

The secret key for the symmetric algorithm.

Object Oriented Interface

public function getKey();
public function setKey($value);

Procedural Interface

ipworksencrypt_rc4_get($res, 5 );
ipworksencrypt_rc4_set($res, 5, $value );

Default Value

Remarks

This secret key is used both for encryption and decryption. The secret key should be known only to the sender and the receiver. The legal key size varies depending on the algorithm.

If this property is left empty and KeyPassword is specified, a Key value will be generated by the class as necessary.
