Hashicorp also provides digital signatures for Packer artifacts. If you want to check the integrity of your files you should verify they are properly signed like so, for example:

$ gpg --search-keys  security@hashicorp.com  
# Pick the correct one
$ wget https://releases.hashicorp.com/packer/1.2.4/packer_1.2.4_linux_amd64.zip
$ wget https://releases.hashicorp.com/packer/1.2.4/packer_1.2.4_SHA256SUMS.sig
$ wget https://releases.hashicorp.com/packer/1.2.4/packer_1.2.4_SHA256SUMS
$ gpg --verify packer_1.2.4_SHA256SUMS.sig packer_1.2.4_SHA256SUMS
# Should return 0 and indicate a `Good signature from "HashiCorp Security <security@hashicorp.com>"'
cat packer_1.2.4_SHA256SUMS | grep packer_1.2.4_linux_amd64.zip | sha256sum -c
# Should return 0 and `packer_1.2.4_linux_amd64.zip: OK`
