trezor-agent VS sops

It doesn't support signing and authentication subkeys (But maybe it will soon!).

GPG "master keys" are on the Trezor, which has no mass storage. You can read more how to use if for GPG in here: https://github.com/romanz/trezor-agent/blob/master/doc/README-GPG.md. Trezor needs a PIN + passphrase typed on the device to be secure from physical attacks (Google: trezor hacked).

I use romanz/trezor-agent and it is recommended on the official trezor wiki.

it looks like someone on the github for the Trezor GPG has worked on it but I have no clue how to run this script. Here's the first link I found under the issues tab.

I'd been working with the trezor-gpg and trezor-ssh features recently, but found them difficult to configure in Windows. When I saw the WSL-2 article on usbipd, found everything worked great.

Ledger/Trezor have solved this since ~2016. I have a Ledger that has a private key inside and using a small open source tool (https://github.com/romanz/trezor-agent) I can SSH into machines, sign random data and Github commits and FIDO authenticate into several websites. All of that and knowing that these devices offer some of the best security out there.

SSH/PGP agent is a proxy application intended to work with https://github.com/romanz/trezor-agent

My script just sets up default .sops.yaml for https://github.com/getsops/sops

You can further edit .sops.yaml(eg have multiple of them) and decide how you split secrets in your directory tree to further customize who can decrypt the secrets.

It works pretty well for prod/dev splits, etc

Mozilla SOPS (Secrets OPerationS) is an open-source command-line tool for managing and storing secrets. It uses secure encryption methods to encrypt secrets at rest and decrypt them at runtime. SOPS supports a variety of key management systems, including AWS KMS, GCP KMS, Azure Key Vault, and PGP. It's particularly useful in a DevOps context where sensitive data like API keys, passwords, or certificates need to be securely managed and seamlessly integrated into application workflows.

Encrypted secrets thanks to SOPS and Age

We do the exact same thing to keep track of some credentials we use sops[1] and AWS KMS to separate credentials by sensitivity, then use the git differ to view the diffs between the encrypted secrets

Definitely not best practice security-wise, but it works well

For anyone new to SOPS like I was - https://github.com/getsops/sops

I've found this is largely solved by strictly separating plain config and secrets, and then having secrets pull from GCP secret manager / vault / whatever.

You can then commit all the config (including the secret identifiers) and it all just works so long as you're authenticated with your secret storage system.

We do this for the live configuration as well in line with Gitops and find it to work well.

If you don't want to use a cloud secret manager you can also use something like https://github.com/getsops/sops to commit the encrypted secrets safely

Basically, the simpler the better --just encrypt your secrets and check them in to version control.

We use SOPS[0] for this, and have found it to be pretty nice.

The answer is that secrets shouldn't be stored in the git repo at all, but somewhere safe like a password manager or Mozilla's SOPS which people seem to love.

Unfortunately, the SOPS project is in some sort of a limbo state and there has been quite a long period with limited maintenance and unclear position from Mozilla. Despite the project being accepted into the CNCF, it's still unclear what will happen with it going forward.
