How to verify the Armory binary on Linux (in this case, Ubuntu):

(1) Do 'cd' to the directory where the deb file was downloaded.

(2) Do:

Code:

$ sha256sum armory_0.93.2_ubuntu-64bit.deb

(substituting the name of the particular deb file which you downloaded).

This should produce something like the following output:

Code:

677b484cbafcaff8a520cd4526beff985ca73eed54b437fa5cfdc123bd2c517a armory_0.93.2_ubuntu-64bit.deb

(3) Look in the file:

Code:

armory_0.93.2_sha256sum.txt.asc

and make sure that the hash shown in the above file for the file being checked (in this case, armory_0.93.2_ubuntu-64bit.deb) matches the hash produced in the output for step (2).

(4) Also verify the signature of the file:

Code:

armory_0.93.2_sha256sum.txt.asc

by doing:

Code:

$ gpg --verify armory_0.93.2_sha256sum.txt.asc

This should produce the following output:

Code:
