Exclusive or operation for encryption and decryption
In an exclusive or operation, if a character (or value) x and a value m perform an exclusive or operation to obtain y, then use y and m to perform an exclusive or operation to restore x,
Conversion from: c |, |, &, &, Or ,~ ,! Operation
Bitwise operation
The bitwise operation component can only be integer or numeric type data. bitwise operations regard the operation object as Bit String information consisting of binary digits to
In this article, we will use the C language to implement the function of exchanging two variables of any type. It is difficult to use C for any type. If it is C ++, we can easily use the template function:
template inline void swap(T& t1, T& t2)
The ^ operator in the PHP language is often used for encryption operations, and the decryption can also be done directly using ^, but when communicating with other languages, other languages such as objective-c may not be able to parse PHP's ^,
1. bitwise and operation bitwise AND operator "&" are binary operators. Its function is the binary phase corresponding to the two numbers involved in the operation. The result bit is 1 only when the two binary numbers are 1. Otherwise, the result

For example, I want to make a connection to a database in the bat file or to import or export data in a database (mysqldump) This will use the database password.If the password in this database is also a special escape to run the bat file, otherwise
The problem of exclusive or operation on bytes after phpmd5 is encrypted $ string = "! & 22E2 &! '& 5aSJ ^ # $ & 6 $ Md5 = md5 ("0e2c83d839c026a5e05303167feb90". md5 ($ string, true), true );
Performs an exclusive or operation on the 16-bit binary
The symbol of XOR is ^. Bitwise XOR, the equivalent long Binary mode performs a bitwise XOR OR operation on each bit of a bitwise or binary number. The result of the operation is that if a bit is different then the bit is 1, otherwise the bit is the

When writing a program, we often encounter various settings, for example, set the dock status of the four sides of the window (for example,
Today, we are looking at how OpenGL loads TGA images as textures.CodeWhen I saw a line of code about RGB (a) sequence conversion, I was confused at first. Later I thought about how to implement the switching operation.
