sql md5 function

MD5 is a secure hashing algorithm, input two different plaintext will not get the same output value, according to the output value, can not get the original plaintext, that is, its process is irreversible; So to decrypt MD5 there is no ready-made

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. The

MD5, all known as Message Digest algorithm 5 (the fifth edition of the Messaging Digest algorithm). For more information, please refer to Wikipedia: MD5 MD5 is encrypted with a byte array, but we typically take its hexadecimal string notation, and

From: http://blog.csdn.net/lele5000/article/details/6704247 Preface: The implementation of MD5 and base64 functions is not the focus of this article. The focus is on the trouble of Character Set conversion during implementation.   Recently, due to

Sometimes, in the development process, if you accidentally change the password of the project administrator account and forget, the existence of the password in the database is MD5 encrypted, what happens at this time? The most rookie of me, just

Sometimes, in the development process, if accidentally changed the project Administrator account password and forgot, there is the password in the database is MD5 encryption, this time how to do? The most rookie of me, just at the beginning is also
