Check Sum | Table O Contents

Affirming a download via Check Sum is a smart move …

Hash v Hash

Hint. Watch for the long “hash” number at the end of the check sum.

Just match it up against the published “hash” number for that particular software download, and if the “hash” match, you should be good to go!

Check the Sum

You can always check the sum of the downloaded program from the Terminal of your Apple development machine, as follows:

From the Terminal prompt of your downloads folder, type the following md5 command to check the sum of the MIST browser installer program, for example, as follows:

md5 Mist-macosx-0-9-0.dmg


MD5 (Mist-macosx-0-9-0.dmg) = 417eb91b23dbb23d208709adeae8f15b

The Published Hash

Check against the published hash …


Versus the hash from the download.

Looks like they are both sympatico!

Example Two

The published MD5 “hash” for the Ethereum wallet installer (.dmg) is = f19165e94dc1facba3289f43abcda58b

The name of the Ethereum wallet installer is Ethereum-Wallet-macosx-0-9-0.dmg

Put ‘em both together at the Terminal window of your downloads folder to see if the two “hash” match up.

Type the following md5 command at the Terminal prompt, as follows:

Note. Make sure you are in the same folder at the Terminal prompt where your (.dmg) file resides

md5 Ethereum-Wallet-macosx-0-9-0.dmg

Returns …

MD5 (Ethereum-Wallet-macosx-0-9-0.dmg) = f19165e94dc1facba3289f43abcda58b

Line ‘em Up

To check the two “hash”, just line ‘em up on a blank (.txt) document, as follows:

Published Hash …


Hash from the download …

Looks like they are both sympatico!

You should be good to go.

Alternative Route

Alternatively, you can also just download the Ethereum “soft” wallet from the main Ethereum website at Ethereum [2].

No Hack In Transit

The installer program ( .dmg ) will check the sum of the program downloaded to make sure it has not been hacked in transit in the open.
