Php custom encryption and decryption program instance
This article mainly introduces php user-defined encryption and decryption programs. The example analyzes User-Defined encryption and decryption files and their usage, which has some reference value. For more information, see
This example describes the php custom encryption and decryption program. Share it with you for your reference. The specific analysis is as follows:
PHP3 Cryption is a very easy-to-crack, insecure encryption function and
or decrypt a password. You can also decrypt or encrypt data multiple times through loops or other methods. The characters in the alphabet also change. All these things allow you to modify and consolidate encryption.
What is the best part? You can encrypt and decrypt a piece of paper and a pencil. This takes a long time, but you don't need a computer nearby to use it. if you have lost code, if you still remember that your technology can be decrypted.
Php custom encryption and decryption program
PHP3 Cryption is a very easy-to-crack, insecure encryption function, and should not be a very important thing to use. Although encryption is good, it will not impede the rigorous test of the sophisticated cracking program.
But try it... this is a great way to encrypt and decrypt strings. It is bidirectional with many hidden nest functions. You can encrypt or decrypt a password. You can also decrypt or encrypt data multiple times through loops or other

PHP3 Cryption is a very easy to crack, unsafe encryption function, should not be very important things to use, although encryption is good, it will not hinder the rigorous testing of cutting-edge cracking procedures.

Analysis:
Alpha is very powerful here, filtering numbers and special characters, and even spaces are filtered. Fortunately, I initialized with the addition of a parameter "", so that the space retained.
Why is it so magical?
This is the core code.

How to enter the English phonetic alphabet in word? Very simple and easy to use
Inputting English phonetic symbols on the keyboard in Word, Excel, and PowerPoint has always been a headache for many people. Word has not provided a solution. Many people think of inserting special characters, but it is difficult to find all 48 international phonetic symbols and it is very complicated to use. Some others choose to use Jinshan's image library for pasting,
actually returned, and only the returned value is true. Of course, the returned value is still of the previous type (for example, the list returned in the example is still list)
val nums = listof(1, 2, 4, 5)list.map{ it *it } //
The printed result is
[1, 4, 16, 25]
Prediction: all, any, count, and find
All returns true only when all conditions meet the specified conditions (predictions). If any, the system determines that at least one condition is met. find finds the first specified condition,
it in detail. it's easy to see what it is. The following is an example:
The code is as follows:
[{'alphabet': 'K'}, {'alphabet': 'A'}, {'alphabet': 'V'}, {'alphabet': 'L'}, {'alphabet': 'E'}, {'alphabet
Three basic factors for advanced programming languages:Syntax: A constituent rule that describes the composition of a language (including lexical rules and grammatical rules)Semantics: Describing the meaning of grammatical componentsPragmatics: A method for describing the use of grammatical componentsFormal language theory (formal language theory) is a mathematical approach to the generation, general nature and rules of natural languages (such as English) and artificial languages (such as progra
);But the string itself is an object constant. The string class does not provide any way to alter an existing object.
String S1 = + "grams to a kilogram."; Grams to a kilogram.String s2 = "Pi is less than" + 3.1416+ '. Pi is less than 3.1416.String S1 = ' a ' + 3.14 + "!\n"; 100.14!\n
String Word; Word. length ();
The Member method is the means by which the Java object implements the behavior, and the class method is the service provided by the class.
