Please use the offline bundles posted on the 0.92.3 tab, which is perfectly compatible when paired with an online computer using 0.93.1.Update: If you already have a verified copy of Armory version 0.91 or higher, you can use the new secure downloader feature to get upgrades and/or installers for other systems.See the next section for more info.If you don’t have a verified copy of Armory yet, you should follow these instructions to verify the first Armory installer you download via GPG.Armory is used by some of the most heavily-invested, and most paranoid Bitcoin enthusiasts and cloud miners for maximum privacy and security.If you are in this category, it is recommended you verify that your Armory installers have not been altered in any way.Armory Ubuntu/Debian packages (*.deb files) are signed directly using our Offline Signing Key (GPG) (0x98832223).And each release comes with a signed file containing the SHA256 hashes of each installer.Unfortunately, it is not easy to verify these signatures unless you have access to a Linux machine.

At the moment, the verification procedure on Windows is very difficult.To verify in Linux, “cd” to the directory containing the installer (usually Downloads), download and import the Armory signing key from the ubuntu key-server, install the signature verification program, and then use it verify the signatures on the *.deb files: $ cd Downloads # the directory containing the *.deb $ 98832223 $ sudo apt-get install dpkg-sig $ dpkg-sig --verify *.deb If everything goes smoothly, you will see the following output: `$ 98832223 gpg: key 98832223: public key “Alan C. Reiner (Offline Signing Key) ” $ dpkg-sig –verify *.deb Processing armory_0.85-beta_amd64.deb… GOODSIG _gpgbuilder 821F122936BDD565366AC36A4AB16AEA98832223 1353699840 ` Notice the 98832223 at the end of the “GOODSIG” line.That is the key fingerprint and if it does not match, do not use that installer!To be extra sure, you can check the last 16 characters, which should be 4AB16AEA98832223.

The last set of digits (1353699840) is simply a timestamp indicating when the signature was made.This will be different for every new and can safely be ignored.If you do not currently have any version of Armory installed or currently have a version older than 0.91, you should consider verifying the installers via GPG as described above.However, since version 0.91, we have integrated the “secure downloader” which retrieves download links and cryptographic signatures from our server, and verifies those cryptographic signatures for you.This can also be used to download installers for other systems.You can open the secure downloader via Help > Update Software from the main window.Make sure you select your operating system, OS version, and architecture (32 or 64-bit) before selecting your package.Furthermore, if you already have a copy of Armory 0.91+ on your offline computer, you can select the option “Save with offline-verifiable signature” before you click the “Download” button.
