Anaconda Content Trust: conda package signature verification#

The conda signature verification feature requires conda version 4.10.1 (or later). Using it allows you to detect tampering with packages and package metadata between our secure build process and the end user’s install process. Based on The Update Framework (TUF), it provides defense against a wide variety of attacks.

Caution

Conda signature verification must be turned on, as it is currently off by default.

Setup#

Install the necessary packages:

conda install "conda>=4.10.1" "conda-token>=0.3.0" conda-content-trust

Use conda-token to configure access, turn on signature verification, and empty the index cache:
```
conda token set --enable-signature-verification <YOUR_PRODUCT_TOKEN>
```

Result#

Conda signature verification should now be functional. When you ask conda to install packages from the professional repository, conda will inform you about the signature status of the packages it proposes installing. For example, in this case we’ve run conda install django:

## Package Plan ##

    environment location: /home/s/miniconda3-av2

    added / updated specs:
        - django


The following packages will be downloaded:

Trusted packages are marked with (INFO: package metadata is signed by Anaconda and trusted).

If no signatures are currently provided for a package–for example, if you are installing from third-party channels–that message will not be provided.

Further, if the trusted signatures do not match the data, tampering may have occurred, and you will receive a warning instead: (WARNING: metadata signature verification failed).

To turn the feature off, you can adjust your conda configuration:

conda config --set extra_safety_checks false
