using md5

As per the documentation on MySQL I moved the storage of passwords from using password () to using MD5 (). I read a number of places that stated that this was a method that couldn't be reversed and it was far more secure than the previous method. I

The code for generating MD5 with c # is as follows: {code ...} the MD5 generated by the above code is f5da53705563c657581a6d0853286fdc. The problem is that the MD5 generated by c # is inconsistent with the MD5 generated by PHP. due to service

First, let's introduce the concept of MD5 and SHA1.MD5The full name of MD5 is message-digest algorithm 5 (Information-Digest algorithm). 128-bit length. At present, MD5 is an irreversible algorithm.It has high security. It corresponds to any string
