MD5-checksum for OSX 10.7 Lion (version released via Mac Appstore)

I wonder about checksum too.

Today I tried to use function of "Internet recovery" (command+R during startup) in order to get InstallESD.dmg file locally (for using it times after as ORIGINAL backup dvd, because I dont even want to hear anything about MacOSX distribution files on different torrent resources, etc.). I succseeded in saving dmg file, but I was quite confused when I get sha1 checksum that any internet search engine that I've tried to use don't even know it. I saw log file that says that failed to download correctly chunks were re-downloaded, etc., but as a some sort of tech specialist I know that there is possibility for chunk files in some cases not being merged correctly. While trying to mount dmg file it tries to check it's integrity, but we all know that it's not a kind of panacea procedure.

So sha1 (for a good sake) checksum is the only way to be happy of knowing that in your Mac everything IS the way it MUST be.

So there are several questions I might mention about that:

1. What are correct checksums for MacOSX 10.7.5 (11g63) release?

2. Is there an option to get PRODUCT's direct download link for users, who have devices with same PRODUCT preinstalled on it (for examle in "Manage your AppleID" section)?

Well, I knew that my questions would not be answered, so I performed attempt to find answer for my first question by myself.

Here are results (brief mode):

InstallESD_1: unpacked dmg (downloaded from WWW)

InstallESD_2: unpacked dmg (saved during "Internet recovery")

user@dd:~/Downloads$ diff -qr InstallESD_1/ InstallESD_2/

So sha1 for MacOSX 10.7.5 (11g63): a044fc01fa75b1f255dbdd6ea4fefa30cef147b0

is good.

For those who are interested in question/
