Algorithm
It is often asked why the MD5 algorithm has some program fragments that return full numeric results and some return a mixed string of numbers and letters.
In fact, two return results just because of the different display of encryption
Basic principle
In C # Implementation in this process, we need to do the following steps:
Gets the local host file corresponding to the current process;
Open this file stream;
The hash algorithm is determined to compute the hash of the file
This afternoon the FlyMe OS brand new firmware for MX/MX2 is updated, where 2.5.3 is oriented to MX, while 3.5.6 faces MX2. The former fully optimizes the music playback and joins the Dirac HD sound function, the latter ushered in the nine Sudoku
Principle: Use the different MD5 value to carry on the contrast of the file.
Operation background:
XP installation CD-ROM;
Virus samples;
U
Ubuntu 7.10 LiveCD
Several programs needed to compare MD5 and convert binary file formats

Mcrypt_get_block_size: Gets the chunk size of the encoding.
Mcrypt_get_cipher_name: Gets the name of the encoding.
Mcrypt_get_key_size: Gets the size of the coded key.
MCRYPT_OFB: Use OFB to

In fact, in asp.net programming, you don't have to call md5.asp to encrypt your data. Classes in dotnet: System.Web.Security.HashPasswordForStoringInConfigFile ()

Type casts in PHP are very similar to those in C: precede the variables to be converted with the target type enclosed in parentheses.
The allowed casts are:
(int), (integer)-Convert to integral type
(bool), (Boolean)-Convert to Boolean
