crypt hash

Data encryptionData encryption uses cryptography technology to encrypt information, realize the concealment of information, and thus play a role in protecting information security. It uses the encryption algorithm and the encryption key to process

Before introducing the encryption function, let's first introduce the principle of data encryption: it is to process the original plaintext file or data according to a certain algorithm to make it a piece of unreadable code, it is usually called

You should use the complete result obtained by crypt () as the salt value for password verification to avoid problems caused by different hash algorithms. (As described above, the password hash based on the standard DES algorithm uses a 2-character

Md5 combined with crypt = invincible password. I like SQL injection. I have checked many websites before and after. ASPPHPJSP found that the MD5 encryption algorithm is basically used. MD5 cannot be broken, but MD5 cannot be reversed. However, I
