PHP encryption function-md5 () function encryption what is MD5 () function? MD5 () function is the MD5 hash value of the calculator string, using MD5 algorithm, the full name of MD5 is Message-DigestAlgorithm5, it is used to calculate data
Use the MD5 conversion algorithm to prevent brute force cracking. MD5 is the most common cryptographic algorithm in Web applications. Because MD5 is irreversible, the ciphertext obtained after MD5 calculation cannot be obtained through reverse
MD5 is the most common cryptographic algorithm in Web applications. Because MD5 is irreversible, the ciphertext obtained after MD5 calculation cannot be obtained through reverse algorithms.
Looking back at the original intention of using MD5 to
Conversion | algorithm
MD5 is the most commonly used cryptographic encryption algorithm in Web applications. Since the MD5 is irreversible, the ciphertext after MD5 calculation can not get the original text through the reverse algorithm.

Md5 combined with cryp = invincible password, read md5 combined with cryp = invincible password, because I like SQL injection, and I have detected many websites before and after. ASPPHPJSP found that the MD5 encryption algorithm is basically used.
This article describes how to obtain the MD5 value of a file in PHP and determine whether the file has been modified. MessageDigestAlgorithmMD5 (the fifth version of the message digest algorithm in Chinese) it is a hash function widely used in the
We are in the development of PHP Web site using encryption technology is MD5, then the use of MD5 encryption algorithm can be cracked or MD5 encryption reversible ? Let's take a look at two commonly used PHP data encryption techniques.PHP Data
Because I like SQL injection, and I have detected many websites before and after. ASPPHPJSP found that the MD5 encryption algorithm is basically used. it is said that MD5 cannot be undone, but MD5 cannot be reversed, but it can be cracked by brute
