of the most secure hashing algorithms, and is widely used. The idea of the algorithm is to receive a clear passage, it is then converted into a paragraph (usually smaller) cipher in an irreversible manner, and can be simply understood to take a string of input codes (called Pre-maps or information) and convert them to a shorter, fixed number of output sequences that are hashed (also A process called an information digest or information authentication code. The hash function value can be said to
SHA1 Encryption Algorithm
SHA is a data encryption algorithm, which has been developed and improved by encryption experts for many years and has become one of the most secure hashing algorithms, and is widely used. The idea of the algorithm is to receive a clear text and then convert it into a paragraph (usually smaller) cipher in an irreversible way, or simply to take a string of input codes (called Pre-maps or information) and convert them to a shorter, The process of a fixed number of digits

Enabling SSH's powerful chroot capabilities
In previous versions of OpenSSH 4.8P1, to support Chroot, third-party modifications must be used. But since OpenSSH 4.8P1, the chroot functionality has been built-in, and can be set up directly on the server system (CentOS 5.5).

If you customize a datatype= "Zh2-4" that represents 2 to 4-bit Chinese characters, then datatype= "Zh2-6" represents 2 to 6-bit Chinese characters.After version 5.2, datatype supports rule accumulation or single selection. Use "," to separate the rule accumulation; A delimited representation rule is multiple, that is, as long as one of the rules can be verified, the binding rules will be validated in tu

webform--server controls are Webform with client controls, that is, BS, browser apps. With regard to servers and clients, in WebForm, the server is equivalent to the background (that is, where the C # code is edited) and the client is the foreground (that is, the HTML page). Usage: ① If you want to invoke the JS or jquery function of a client control in a server control, you must add the OnClientClick property to the server's control, Run the sequence, run JS or jquery first, and then run C # V

becomes a duplication, the code will have a lot of duplication. A little better. The check code will be sorted and encapsulated, and there will be more duplicate copies.
2. If I want to add an input validation, then directly modify the Submit function, the function will be significantly bloated, and is to destroy the "open and close" principle.
3. If you modify the Submit function, you must cover the test of the function design, because you do not know when the error will occur or unknown.

Validator: Range validation control.
Tests whether the value of an input is within a specified range. In addition to the same properties as the required Field validator, there are:
Maximum Value Range Maximum
Minimum Value Range Minimum
Tyep the data type of the input value.
3.Compare Validator: Compare validation controls.
Used to compare a user's input to the value or constant of another control on a Web form.
Basic properties:

Form validation server Control
Authentication Introduction
The network formation framework includes an easy-to-use and powerful server control for validation that checks for errors in the input form and displays the prompts to the user when necessary. Add validation controls to the design trap table just as you would add other server controls. Validation controls have different validation types, such as range checking or pattern matching, and adding a RequiredFieldValidator control ensures that
