I. Using RSA certificates to encrypt and decrypt sensitive dataThe certificate standard supports three kinds of asymmetric encryption algorithms: RSA, DSA, Diffie-hellman algorithms. The most common is the RSA algorithm. So this article is encrypted and decrypted using the generated Mytestcert certificate generated by the MakeCert tool in the previous section, which has a 1024-bit key pair for the RSA algor

elements, static text, and sub-forms. The child form is also a CForm object, except that it exists in the cform::elements of another form. A child form can have its own data model, Cform::buttons, and cform::elements collections. When a user submits a form, the data that is filled in the entire form structure is submitted, including the data that is filled in the subform. CForm provides a convenient way to automatically assign input data to the corresponding data attributes and perform data val

232. Implement Queue using StacksImplement the following operations of a queue using stacks. Push (x)--push element x to the back of the queue. Pop ()--Removes the element from in front of the queue. Peek ()--Get the front element. Empty ()--Return whether the queue is empty. Notes: You must use only standard operations of a stack--which means only push to top , peek/pop
