Secretive

Secretive is an app for protecting and managing SSH keys with the Secure Enclave.

Why?

Safer Storage

The most common setup for SSH keys is just keeping them on disk, guarded by proper permissions. This is fine in most cases, but it's not super hard for malicious users or malware to copy your private key. If you protect your keys with the Secure Enclave, it's impossible to export them, by design.

Access Control

If your Mac has a Secure Enclave, it also has support for strong access controls like Touch ID, or authentication with Apple Watch. You can configure your keys so that they require Touch ID (or Watch) authentication before they're accessed.

Notifications

Secretive also notifies you whenever your keys are accessed, so you're never caught off guard.

Support for Smart Cards Too!

For Macs without Secure Enclaves, you can configure a Smart Card (such as a YubiKey) and use it for signing as well.

FAQ

There's a FAQ here.

Auditable Build Process

Builds are produced by GitHub Actions with an auditable build and release generation process. Starting with Secretive 3.0, builds are attested using GitHub Artifact Attestation. Attestations are viewable in the build log for a build, and also on the main attestation page.

A Note Around Code Signing and Keychains

While Secretive uses the Secure Enclave to protect keys, it still relies on Keychain APIs to store and access them. Keychain restricts reads of keys to the app (and specifically, the bundle ID) that created them. If you build Secretive from source, make sure you are consistent in which bundle ID you use so that the Keychain is able to locate your keys.

Backups and Transfers to New Machines

Because secrets in the Secure Enclave are not exportable, they are not able to be backed up, and you will not be able to transfer them to a new machine. If you get a new Mac, just create a new set of secrets specific to that Mac.

Security

Secretive's security policy is detailed in SECURITY.md. To report security issues, please use GitHub's private reporting feature.
