Verifying the PGP signature of AWS OpsHub (optional) - AWS Snowcone User Guide

Verifying the PGP signature of AWS OpsHub (optional)

The AWS OpsHub application installer package for the Linux operating system are cryptographically signed. You can use a public key to verify that the installer package is original and unmodified. If the files are damaged or altered, the verification fails. You can verify the signature of the installer package using GNU Privacy Guard (GPG). This verification is optional. If you choose to verify the signature of the application, you can do it at any time.

You can download the SIGNATURE file for the Linux operating system installer from AWS Snowcone Resources or Snowball Edge Resources.

To verify the AWS OpsHub install package on for the Linux operating system

  1. Copy the following public key, save it to a file, and name the file. For example, opshub-public-key.pgp.

-----END PGP PUBLIC KEY BLOCK-----

  2. Import the public key into your keyring, and note the returned key value.

    GPG
    gpg --import opshub-public-key.pgp

    Example output

    gpg: key 1655BBDE2B770256: public key "AWS OpsHub for Snow Family <aws-opshub-signer@amazon.com>" imported
gpg: Total number processed: 1
gpg:               imported: 1

  3. Verify the fingerprint. Be sure to replace key-value with the value from the preceding step. We recommend that you use GPG to verify the fingerprint. 

    gpg --fingerprint key-value

    This command returns output similar to the following.

    pub   rsa4096 2020-12-21 [SC]
      372F A5E9 4869 8F77 D1B3  AFAA 2181 CF5A 74F3 45F1
uid           [ unknown] AWS OpsHub for Snow Family <aws-opshub-signer@amazon.com>
sub   rsa4096 2020-12-21 [E]

    The fingerprint should match the following:

    372F A5E9 4869 8F77 D1B3 AFAA 2181 CF5A 74F3 45F1

    If the fingerprint doesn't match, don't install the AWS OpsHub application. Contact AWS Support.

  4. Verify the installer package, and download the SIGNATURE file according to your instance's architecture and operating system if you haven't already done so.

  5. Verify the installer package signature. Be sure to replace signature-filename and OpsHub-download-filename with the values that you specified when downloading the SIGNATURE file and AWS OpsHub application.

    GPG
    gpg --verify signature-filename OpsHub-download-filename

    This command returns output similar to the following.

    GPG
    gpg: Signature made Mon Dec 21 13:44:47 2020 PST
gpg:                using RSA key 1655BBDE2B770256
gpg: Good signature from "AWS OpsHub for Snow Family <aws-opshub-signer@amazon.com>" [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: 9C93 4C3B 61F8 C434 9F94  5CA0 1655 BBDE 2B77 0256

    When using GPG, if the output includes the phrase BAD signature, check whether you performed the procedure correctly. If you continue to get this response, contact AWS Support and don't install the agent. The warning message about the trust doesn't mean that the signature is not valid, only that you have not verified the public key. A key is trusted only if you or someone who you trust has signed it.
