keyringrs

A Python binding for keyring-rs.

While keyring is a great tool, it doesn't fully meet our general requirements due to the following reasons:

• Native Linux Keyutils Support: We need seamless integration with keyutils on Linux.
• Proper Memory Management on macOS: We perform numerous key queries, and keyring has known memory management issues on macOS (see issue jaraco/keyring #670).

The keyringrs is not plan as the alternative of keyring. For CLI tool and more generic use cases I recommend to go to keyring.

Aside from our specific requirements with macOS and Linux keyutils, this library can serve as a backup solution if there are unresolved issues. While it doesn't guarantee a fix for the problems encountered, it can be a helpful tool to distinguish whether the issue stems from the library itself or from system configuration.

This library aims to maintain API compatibility with keyring-rs as closely as possible. It therefore provide built-in support following platform-specific credential stores inherited from keyring-rs:

• Linux: The DBus-based Secret Service, the kernel keyutils, and a combo of the two (see below for example on how to control to use only keyutils).
• FreeBSD, OpenBSD: The DBus-based Secret Service.
• macOS, iOS: The local keychain.
• Windows: The Windows Credential Manager.

Installation

To install the package, simply run:

pip install keyringrs

Usage

Here's a quick example of how to use keyringrs:

from keyringrs import Entry

# Create an entry for the given service and username
entry = Entry("my-service", "my-name")

# Set a password
entry.set_password("0Xl$$K6o2bBwDe")

# Retrieve the password
password = entry.get_password()
print(f"My password is '{password}'")

# Delete the credential
entry.delete_credential()

In linux, by default it assume it used in a desktop distro with libdbus installed. For the fallback support to use only keyutils, the key stored will disappear after reboot.

from keyringrs import Entry, CredentialType

# Create an entry use only keyutils in linux
entry = Entry("my-service", "my-name", credential_type=CredentialType.KeyUtils)

This interface follows the same logic as keyring-rs to ensure consistency and ease of use.

Ack

There was an effort five years ago with pyrust-keyring. However, over the years, keyring-rs has gained more features, become more robust, and slightly diverged from the original keyring library. It would be beneficial to have a proper wrapper for it.

Additionally, pyo3 has significantly improved, making it much easier to create wrappers and distribute the library on PyPI.
