Verifying Solaris CD Downloads with md5 Checksum on Ubuntu

I didn't know weather to post this in the Solaris or Linux forum so move it if necessary.

In the Solaris 10 CD Download Instructions, it says:

Quote:

Once you have downloaded a file, you should check that it has not been corrupted during the download before burning it to a CD.
For that, you need to do an "md5 checksum", which compares your downloaded file against the file you would find on the server.

I open up a Terminal (I'm running Ubuntu Linux) and do a man on md5. It gives me this syntax:

Code:

SYNOPSIS
       openssl dgst [-md5|-md4|-md2|-sha1|-sha|-mdc2|-ripemd160|-dss1] [-c]
       [-d] [-hex] [-binary] [-out filename] [-sign filename] [-passin arg]
       [-verify filename] [-prverify filename] [-signature filename] [file...]

So I run it on all the zip files I downloaded and the iso files I extracted from them:

Code:

brad@rockstar:~/Solaris 10 5-09$ openssl dgst -md5 sol-10-u7-ga-x86-v1.iso sol-10-u7-ga-x86-v1-iso.zip sol-10-u7-ga-x86-v2.iso sol-10-u7-ga-x86-v2-iso.zip sol-10-u7-ga-x86-v3.iso sol-10-u7-ga-x86-v3-iso.zip 
sol-10-u7-ga-x86-v4.iso sol-10-u7-ga-x86-v4-iso.zip sol-10-u7-ga-x86-v5.iso sol-10-u7-ga-x86-v5-iso.zip
MD5(sol-10-u7-ga-x86-v1.iso)= 936ae7424f9e4e502b0c5afb31c76fab
MD5(sol-10-u7-ga-x86-v1-iso.zip)= e9b7a2ddc2534ca34afae192f3257e25
MD5(sol-10-u7-ga-x86-v2.iso)= 23732a79c43531b9b983a806bca8c37c
MD5(sol-10-u7-ga-x86-v2-iso.zip)= 7aa8e8db4821d227a926ba95dd4ef223
MD5(sol-10-u7-ga-x86-v3.iso)= 512ac1b5a226f505782401e98a1a371e
MD5(sol-10-u7-ga-x86-v3-iso.zip)= 3a9897d23a9c3b3b4144010ca17625a8
MD5(sol-10-u7-ga-x86-v4.iso)= f99e845473c85eadff9c6fbba47ccd32
MD5(sol-10-u7-ga-x86-v4-iso.zip)= 539efa6291722c0ad2699a4ba10b146a
MD5(sol-10-u7-ga-x86-v5.iso)= 1bc93383264179ef43a0df17cb130259
MD5(sol-10-u7-ga-x86-v5-iso.zip)= 738aa51a976de67c8721d21f5f4ec7d6

All the strings that are outputted match the strings in the file I also downloaded from the same place as the zip files containing the Solaris iso images. Does this mean that it verified the files and I'm good to install?
