MD5 ()MD5 () returns the hash value by default as a 32-character hexadecimal number, which accepts two parameters, the first is the string to encrypt, the second is a Boolean value of Raw_output, the default is False, and if set to TRUE,MD5 ()

The following articles mainly introduce how to use MySQL encryption functions to protect sensitive data on websites. If you are using a MySQL Web application, it can store passwords or other sensitive information in applications. Protecting this

The crypt () function can complete one-way encryption functions. String crypt (String str [, string salt]); STR: is a string that needs to be encrypted; salt: The interference string used for encryption. If the salt is omitted, a disturbance

In the development process of the website, we often need to encrypt some data (such as user password), this article mainly introduces several common cryptographic functions of PHP. MD5 Encryption: String MD5 (string $str [, bool $raw _output =

There are many encryption functions in php functions, one of which can implement data encryption functions is called the crypt () function. The crypt () function uses a one-way algorithm without corresponding decryption functions. It returns a

Using MySQL encryption functions to protect sensitive data on Web sites if you are running a Web application that uses MySQL, it is a great opportunity to store passwords or other sensitive information in the application. Protecting this data from

CommentsSummary: cryptography is a technical science that studies the compilation of passwords (encryption: encode) and deciphering passwords (decryption: decode. The objective law of password change is studied. It is used to compile passwords to
