This repository contains the decred installers and the installer manifests.
For the binary archives, binary manifests and release notes please go to decred-binaries.
Each release contains a manifest file with sha256 hashes for the installers in that release. To verify these, you will need:
- SHA256 - Once you download your file(s), you need to check their SHA256 hashes, so you may need to download a tool to do this, depending on your OS.
- GnuPG or PGP - This is required to import public keys and verify signatures. Examples below use GnuPG.
The steps to verify the binaries are as follows:
Download the file manifest (manifest-dcrinstall-vX.X.X.txt), the signature for the file manifest (manifest-dcrinstall-vX.X.X.txt.asc), and the installer for your OS from here.
Obtain the SHA256 value for the installer for your OS and check that it matches the value in the file manifest, e.g. for 64-bit Linux
$ sha256sum dcrinstall-linux-amd64-v0.3.0 a53004599daeab51c0e86af026748b7aa55ff9e5d4844bef3b7d8ccf8a5d72a9 dcrinstall-linux-amd64-v0.3.0
Import the Decred Release Signing Key in GnuPG.
$ gpg --keyserver pgp.mit.edu --recv-keys 0x6D897EDF518A031D gpg: requesting key 518A031D from hkp server pgp.mit.edu gpg: /home/user/.gnupg/trustdb.gpg: trustdb created gpg: key 7608AF04: public key "Decred Release <firstname.lastname@example.org>" imported gpg: Total number processed: 1 gpg: imported: 1 (RSA: 1)
Verify the signature for the file manifest is valid and created by the Decred Release Signing Key.
$ gpg --verify manifest-dcrinstall-v0.3.0.txt.asc gpg: assuming signed data in `manifest-dcrinstall-v0.3.0.txt' gpg: Signature made Wed 27 Jan 2016 08:56:59 PM UTC using RSA key ID 518A031D gpg: Good signature from "Decred Release <email@example.com>" gpg: WARNING: This key is not certified with a trusted signature! gpg: There is no indication that the signature belongs to the owner.
