C # MD5 encryption,First, let's briefly introduce MD5.
The full name of MD5 is message-digest algorithm 5 (Information-digest algorithm, which was developed by mit laboratory for computer science and rsa data security inc ronald l in early 1990s. developed by rivest and developed by md2, md3, and md4.

Today, I was asked to write a calculator on the iPhone. After all, I was not very familiar with it. I spent an hour writing a calculator in Java. It was very easy to go through the next process. The Code is as follows:

What is MD5 ??. Question: What is MD5 ?? Solution MD5 is the abbreviation of message-digestalgorithm5 (information-Digest Algorithm), which is widely used in encryption and decryption technology.
What is MD5 ??
Solution
MD5 is the abbreviation of message-digest algorithm 5 (
Use the MD5 conversion algorithm to prevent brute-force password 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 algorithms.Looking back at the original intention of using
MD5, the English meaning is the message Digest, namely the Information Digest, is the commonly used information digest algorithm.It is an irreversible algorithm, that is, if a message MD5 digest into a string of code, you will not be able to restore the original information through this string of code.For this feature, MD5 is often used to verify that the passwor
The Code originates from http://blog.andrewpaulsimmons.com/2008/07/md5-hash-on-iphone.html.I have copied it here for processing ing purposes. Please express your appreciations to Andrew for his efforts.

MD5 algorithm, has been known, as a senior or entry-level developers, are called "MD5 ah, know know." A few days ago the program slightly small problem, because some places are encrypted, and some places are not encrypted. A colleague is proud to say that MD5 is a hash algorithm, it is easy to decrypt. I was speechless at the time. Because I remember
A typical application of MD5 is to generate an informational digest (message-digest) of a piece of information (message) to prevent tampering. For example, there are a lot of software under Unix that have a file name with the same filename and file extension. MD5 in this file, usually with a single line of text, roughly structured like this:MD5 (tanajiya.tar.gz) = 37ea8e2c445af24a82caeaea6ced2c5bThis is the

I dreamed of a method to enhance MD5 verification. Woke up and tested it.
Everyone on Earth knows that MD5 has been broken by Wang Xiaoyun !!! Broken !!! Broken !!! Broken !!! Break ~~ (Shut up)
Instead of breaking down, we can use their algorithms to find the MD5 collision within several hours. You use an IBM p
C # often involves encrypting the user's password to decrypt the algorithm, where using MD5 encryption is the most common way to implement it. This paper summarizes the general algorithms and combines their own little experience to share to everyone.I.

Many applications hash and save the user password using the MD5 algorithm, instead of saving the plaintext of the password. MD5 is unidirectional and there is no reverse algori
