Several common encryption functions in PHP and common encryption functions in PHP MD5 encryption: String md5 (string $ str [, bool $ raw_output = false]) 1. by default, md5 () returns a hash value in the hexadecimal format of 32 characters. It accepts two parameters: the first is the string to be encrypted, and the second is the Boolean value of raw_output, the d

Advanced Encryption Standard (English: Advanced encryption Standard, abbreviation: AES), also known as the Rijndael encryption method in cryptography, is a block encryption standard used by the U.S. federal government. This standard, which replaces the original DES, has been analyzed and widely used worldwide. After fi

With the popularity of mobile payment, mobile banking clients are more and more recognized by users, many people feel that since it is the client of the bank, it should be very safe. The report launches the most comprehensive security assessment for the Android mobile client of China's major banks, such as ICBC, CCB, CMB, Bank of Communications, Bank of China and ABC. Original title: Hacker aimed at mobile bankingWith the popularity of mobile payment, mobile banking clients are more and more re

Share it with you for your reference. The details are as foll

How to better encrypt a string? MD5, RSA, DES?Well, none of this is understood.Reference to the degree Niang, so the idea is:For encryption:· Remove a character from the string to be encrypted· The low-byte and Key1 of the characters are taken to make an XOR operation· Take the high byte of the character· Synthesize the data after the operation to a new characterFor decryption:· Remove a character from the string to decrypt· The low-byte and Key1 of t

Simple symmetric encryption algorithm implementation in php and php Encryption Algorithm Preface I found a good symmetric encryption algorithm for PHP on the Internet. In the PHP syntax environment, there are symmetric algorithms that come with urlencode and urldecode, base64_encode, and base64_decode, however, these built-in algorithms cannot be called
