When you download a file on this forum and when a MD5 checksum is available, please check it before flashing your device.

What is MD5 checksum?
MD5 checksum (MD5 hash) is a type of digests of files. It will become totally different if any modification has been made to the file, even a byte.

Why should I use Md5Checker?
  1. To verify the integrity of downloaded files: With Md5Checker, user can calculate MD5 checksum of downloaded files and compare them with provided when downloading via HTTP, FTP, P2P, etc.
  2. To detect unknown viruses: Only-for-existing-viruses DB based anti-virus programs can rarely detect all emerged new (i.e. not in the DB) viruses in time. As a supplement, Md5Checker checks whether files are original. By that user can detect any change of file including virus infection.
  3. To make sure that the installation files are secure: System will be re-infected by viruses time and again while reinstalling software if the installation file had been infected. To avoid this, Md5Checker user can calculate and save the MD5 checksum right after downloaded/copied installation files, i.e. make sure these files are original (This step can be skipped if there are MD5 checksum downloaded/copied along with these files), and verify these files again upon using them.
  4. To make sure that files in a removable storage device are secure: In order to avoid bringing in viruses from using the removable storage device, Md5Checker user can calculate, save MD5 checksum in advance and verify files afterwards in the device. It is also a good idea to copy Md5Checker into the device to be able to check files anywhere and anytime. Note: Don’t forget to check the copied Md5Checker.
  5. To check out the security status of the system: It will indicate that the system was infected if the MD5 checksum of one executable file was changed without any action.
  6. To find out the virus source: It will indicate that one executable file is the virus source if the MD5 checksum of other several executable files have changed unexpectedly after executed this file.
  7. To calculate MD5 checksum for publishing: File distributors and software authors can use Md5Checker to calculate MD5 checksum of their files and publish them on the website.

Hi Guys
I am just starting with the Minix 7 android version and my question is "Is there an MD5 checker available for Linux operating system (Ubuntu) and if so where would I go to down load it?"
Thanks in advance for your help.
