Hi Chinedu.Onwurah,
Once you have the junos loaded on the device you can run the below command;
> file checksum md5 <pathname> filename
You will get a md5 value as the output. <output 1>
After that go to the software download page and select the product and the version.
You will get something like below;
Install Package |
Checksum |
Release |

File Date |
SRX5000 Series |
MD5 SHA1 |
15.1X49-D20 |
tgz |
549,863,886 |

Now click on the MD5 SHA1 link you will get the value of MD5 , it will be <output 2> . Now you can compare the two values and confirm if they are same the file is valid and not tampered with.
