* ISDCltDynCode: client side dynamic code component. ISDCltDynCode provides

* dynamic encrypt and decrypt methods.
|
||
*
|
||
* Usage:
|
||
* 1. Create ISDCltDynCode component, call SDCreateCltDynCode
|
||
* 2. Call ISDCltDynCode.SetDynCode to when getting dynamic code from server
|
||
* 3. To encrypt: call ISDCltDynCode::Encode
|
||
* 4. To decrypt: call ISDCltDynCode::Decode
|
||
* 5. when finish, call ISDCltDynCode::Release to release the component
