Verify Integrity of MongoDB Packages¶
On this page
概述¶
The MongoDB release team digitally signs all software packages to certify that a particular MongoDB package is a valid and unaltered MongoDB release. Before installing MongoDB, you should validate the package using either the provided PGP signature or SHA-256 checksum.
PGP signatures provide the strongest guarantees by checking both the authenticity and integrity of a file to prevent tampering.
Cryptographic checksums only validate file integrity to prevent network transmission errors.
Procedures¶
Use PGP/GPG¶
MongoDB signs each release branch with a different PGP key. The public key files for each release branch since MongoDB 2.2 are available for download from the key server in both textual .asc and binary .pub formats.
Download the MongoDB installation file.¶
Download the binaries from https://www.mongodb.org/downloads based on your environment.
For example, to download the 3.4.0 release for OS X through the shell, run this command:
curl -LO https://fastdl.mongodb.org/osx/mongodb-osx-x86_64-3.4.0.tgz
Download the public signature file.¶
curl -LO https://fastdl.mongodb.org/osx/mongodb-osx-x86_64-3.4.0.tgz.sig
Download then import the key file.¶
If you have not downloaded and imported the MongoDB 3.4 public key, run these commands:
curl -LO https://www.mongodb.org/static/pgp/server-3.4.asc
gpg --import server-3.4.asc
PGP should return this response:
gpg: key A15703C6: public key "MongoDB 3.4 Release Signing Key <packaging@mongodb.com>" imported
gpg: Total number processed: 1
gpg: imported: 1 (RSA: 1)
Verify the MongoDB installation file.¶
Run this command:
gpg --verify mongodb-osx-x86_64-3.4.0.tgz.sig mongodb-osx-x86_64-3.4.0.tgz
GPG should return this response:
gpg: Signature made Fri 12 Aug 2016 03:44:49 PM EDT using RSA key ID A15703C6
gpg: Good signature from "MongoDB 3.4 Release Signing Key <packaging@mongodb.com>"
If you receive a message this error message, confirm that you imported the correct public key:
gpg: Signature made Mon 27 Jul 2015 07:51:53 PM EDT using RSA key ID A15703C6
gpg: Can't check signature: public key not found
gpg will return the following message if the package is properly signed, but you do not currently trust the signing key in your local trustdb.
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: 0C49 F373 0359 A145 1858 5931 BC71 1F9B A157 03C6
Use SHA-256¶
Download the MongoDB installation file.¶
Download the binaries from https://www.mongodb.org/downloads based on your environment.
For example, to download the 3.0.5 release for OS X through the shell, type this command:
curl -LO https://fastdl.mongodb.org/osx/mongodb-osx-x86_64-3.0.5.tgz
Download the SHA256 file.¶
curl -LO https://fastdl.mongodb.org/osx/mongodb-osx-x86_64-3.0.5.tgz.sha256
Use the SHA-256 checksum to verify the MongoDB package file.¶
Compute the checksum of the package file:
shasum -c mongodb-osx-x86_64-3.0.5.tgz.sha256
which should return the following if the checksum matched the downloaded package:
mongodb-osx-x86_64-3.0.5.tgz: OK
