Verify the authenticity of a downloaded asset

Detailed procedure to verify an asset

• Step 1: Identify the downloaded asset on your computer YOUR_ASSET_FILE
• Step 2: Download the signed checksum file from this link CHECKSUM.asc and save it in the same folder as the asset
• Step 3: In your terminal, go to the asset folder by running:

cd ***YOUR_ASSET_FOLDER***

• Step 4: Then verify the checksum of the asset by running:

sha256sum -c ./CHECKSUM.asc 2>/dev/null | grep ***YOUR_ASSET_FILE***

You must see:

./***YOUR_ASSET_FILE***: OK

• Step 5: Download the public key file from this link public-key.gpg and save it in the same folder as the asset
• Step 6: Then import the GPG public key:

gpg --import ./public-key.gpg

You must see something like:

gpg: key : public key "Input Output / Mithril <[email protected]>" imported
gpg: Total number processed: 1
gpg:               imported: 1

• Step 7: Then verify the GPG signature of the checksum file:

gpg --verify ./public-key.gpg ./CHECKSUM.asc

You must see something like:

gpg: Signature made Mon 05 Dec 2022 04:53:54 PM CET
gpg:                using RSA key 35EDE9D47BBA62A2F388E655899ACD26B8BCA0D2
gpg: Good signature from "Input Output / Mithril <[email protected]>" [unknown]
gpg: WARNING: This key is not certified with a trusted signature!
gpg:          There is no indication that the signature belongs to the owner.
Primary key fingerprint: 35ED E9D4 7BBA 62A2 F388  E655 899A CD26 B8BC A0D2

The signature is valid if and only if:

• there is a line with gpg: Good signature from "Input Output / Mithril <[email protected]>"
• there is a line with Primary key fingerprint: 2AC0 7B11 8B23 1443 F544 2D0C 6E2C 1160 3E79 0021

• Step 8:
  If you successfully validated all the steps of this process, then you have successfully verified the authenticity of the asset ✔️
